<b>Solution 1</b><br />
<b>Redundant site (ISP MTG, ISP True Tower)</b><br />
<ul style="text-align: left;">
<li>Customer has link connected to ISP at either MTG or TTW site.</li>
<li>International & Domestic Gatway is primary at MTG and backup is TTW.</li>
<li>International & Domestic Gatway at MTG consists of multiple providers</li>
<ul>
<li> International Link >> TIG, IIG, VSNL</li>
<li> Domestic Link >> CAT-NIX, TIG-NIX, TOT-NIX and TI</li>
</ul>
<li>Some of Internaltional & Domestic provider has backup root</li>
<ul>
<li>TIG >> Primary link/site is at MTG and backup is at TTW (both International and Domestic as well)</li>
</ul>
<li>Equipment which installed International & Domestic link is redundant Hardware for instance CPU, FAN Tray, Power Supply, Port/Interface etc. and maintenace contract also.</li>
<li>Incase of MTG, primary site is down then the backup site is automatically take over</li>
<li>UPS system & Generator backup for both site (MTG and True Tower)</li>
</ul>
<b>Solution 2</b><br />
<b>Redundant ISP(Primary) , TI (Backup)</b><br />
<ul style="text-align: left;">
<li>Customer’s traffic normally flow via ISP </li>
<li>In case of ISP’s Domestic is totally down then Customer’s Domestic traffic automatically flow via TI instead</li>
<li>In case of ISP’s International is totally down then Customer’s International traffic automatically flow via TI instead</li>
<li>In case of both ISP’s Domestic and International are totally down then Customer’s traffic automatically flow via TI instead as well </li>

<div>
<b>Service Level Agreement</b></div>
<div>
<div>
<br /></div>
<div>
<b>1. Guaranteed service level</b></div>
<div>
<br /></div>
<div>
<u>1.1 Availability</u></div>
<div>
The guaranteed availability of the services of the agreement is 99.7% in any calendar month, after which the service availability is classified as “reduced availability”. If the availability of the service falls below 99% in any calendar month then there is “excessive downtime” </div>
<div>
<br /></div>
<div>
<u>1.2 Network latency</u></div>
<div>
If the average network latency in any calendar month for domestic Internet traffic exceeds 50 ms. or for international traffic exceeds 350 ms. then this is a case of reduced availability. If the average network latency in any calendar month for domestic Internet traffic exceeds 80 ms. or for international traffic exceeds 500 ms. then there is excessive latency downtime.</div>
<div>
<br /></div>
<div>
<u>1.3 Packet loss</u></div>
<div>
If the average packet loss in any calendar month for domestic Internet traffic exceeds 1% or for international traffic exceeds 3% then this is a case of reduced availability. If average packet loss in any calendar month for domestic Internet traffic exceeds 2% or for international traffic exceeds 5% then there is excessive packet loss downtime.</div>
<div>
<br /></div>
<div>
<b>2. Service level credits</b></div>
<div>
<br /></div>
<div>
<u>2.1 Reduced availability</u></div>
<div>
In case of reduced availability, ISP will credit designated service fees components up to the equivalent of the service fees during the number of days in the calendar month that the provided service level did not meet the guaranteed service levels.</div>
<div>
<br /></div>
<div>
<u>2.2 Excessive downtime</u></div>
<div>
In case of excessive downtime, ISP will credit designated service fees components up to 10% for every day that the provided service level did not meet the guaranteed service levels, with a maximum of the total service charge for that month.</div>
<div>
<br /></div>
<div>
<u>2.3 Force mature</u></div>
<div>
ISP has committed, where possible, to redundant systems and/or providers of services that are delivers to its customers. In case of service interruptions that are outside the influence of ISP, ISP reserves the right to adjust the service level credits to the level of the service credits that it receives from its suppliers, whom ISP has no control over. ISP will go through reasonable endeavors to claim any damages of its clients at its providers.</div>
<div>
</div>
<div>
<b>3. Service delivery information</b></div>
<div>
<br /></div>
<div>
<u>3.1 Statistics</u></div>
<div>
On request and for certain connection types, ISP can activate bandwidth utilization statistics (MRTG) that can be made available to the customer through a web interface. These statistics can provide the customer with a global indication about his bandwidth utilization. The statistics cannot be used to determine the actual service level delivered by ISP since this depends on many factors one of which is the condition and throughput of the customer premises equipment, which is outside the area of control of ISP.</div>
<div>
<br /></div>
<div>
<u>3.2 SMS alert</u></div>
<div>
Instead of pager alert, ISP can alert the customer by SMS. Customer agrees in that case with the non-priority that SMS services have on the network of mobile providers and will not hold ISP liable for any delays in the notification.</div>
</div>

<b>Detail Description: </b>Before the Cutover:<br />
- Pre-configure the 4500 switch. Ports should be on vlan 15(116.40.193.0/24). Must follow NST guides.<br />
- Assign 116.40.193.5 as MNGT IP.<br />
- Test DHCP of PC when connected to the port<br />
- Burn in test.<br />
<br />
<b>Cutover:</b><br />
- Shutdown 5513.<br />
- Clear out un-necessary cables on the cabinet.<br />
- Mount the 4500<br />
- Check connectivity with the core switch.<br />
- Try getting IP address from DHCP server<br />
<br />
<b>Impact: </b>- No Network Connectivity to Floor 15. Users are asked to move to other floors during the activity.<br />

This article will show how to use Policy-Based Routing to different default routes are used based on the source of the ip address. Let me show you the diagram and the configuration step. The example below should cover basic route-map configuration.

<div style="text-align: center;">
The previous diagram illustrates the structure of Route Map and Policy-Based Routing
</div>
<strong>IP Address Assignment:</strong><br />
<ul style="text-align: left;">
<li><strong>VLAN 10</strong> Management Vlan IP address: 146.10.50.xx/24</li>
<li><strong>VLAN 20</strong> Server Vlan IP address: 146.20.50.xx/24</li>
<li><strong>VLAN 30</strong> Wireless Lan VIP IP address: 146.30.50.xx/24</li>
<li><strong>VLAN 31</strong> Wireless Lan Visitor IP address: 146.30.50.xx/24</li>
<li><strong>VLAN 40</strong> Workstation Vlan IP address: 146.40.50.xx/24</li>
</ul>
<strong>Step 1 - Defining an ACL</strong><br />
Create a simple ACL:<br />
SGHQSL1-4506(config)#ip access-list extended WVIP<br />
SGHQSL1-4506(config-ext-nacl)# permit ip host 146.30.50.31 any<br />
SGHQSL1-4506(config-ext-nacl)# permit ip host 146.30.50.32 any<br />
SGHQSL1-4506(config)#ip access-list extended WVISITOR<br />
SGHQSL1-4506(config-ext-nacl)# permit ip 146.31.50.65 any<br />
<br />
<strong>Step 2 - Creating a route-map</strong><br />
To create a route-map, go into route-map configuration mode, like this:<br />
SGHQSL1-4506(config)#route-map InternetWVISITOR permit 5<br />
SGHQSL1-4506(config-route-map) #match ip address WVISITOR<br />
SGHQSL1-4506(config-route-map) #set ip next-hop 146.10.50.15 <br />
SGHQSL1-4506(config)#route-map InternetWVIP permit 10<br />
SGHQSL1-4506(config-route-map) #match ip address WVIP<br />
SGHQSL1-4506(config-route-map) #set ip next-hop 146.10.50.12 <br />
In this example, this will match all the traffic permitted through access-list <span style="color: purple;">WVIP change the next-hop to 146.10.050.12</span> and all the traffice permitted through access-list <span style="color: purple;">WVISITOR change the next-hop to 146.10.50.15</span><br />
<br />
<strong>Step 3 - Applying the route-map to the interface</strong><br />
Next, you need to apply this policy/route-map to the interface where the traffic is coming in.<br />
SGHQSL1-4506(config)#interface Vlan30<br />
SGHQSL1-4506(config-if)#ip policy route-map InternetWVIP<br />
SGHQSL1-4506(config)#interface Vlan31<br />
SGHQSL1-4506(config-if)#ip policy route-map InternetWVISITOR<br />
<br />

<b>SNMP Concepts</b><br />
SNMP is a protocol that operates at the application layer; it uses the default <strong>UDP port 161 for general SNMP messages</strong> and <strong>UDP port 162</strong> <strong>for SNMP trap messages</strong> and it defines a method of communication between various networking devices and a central manager for use with the monitoring and management of these devices.<br />
<br />
<b>SNMP Versions</b><br />
There are three different versions of SNMP that can be configured:<br />
<br />
<ul style="text-align: left;">
<li><b>SNMPv1 - </b>This was the original version of SNMP; SNMPv1 utilizes a community based security mechanism.</li>
<li><b>SNMPv2c - </b>This was created to update a number of little things within SNMPv1; SNMPv2c utilizes a community based security mechanism.</li>
<li><b>SNMPv3 - </b>This was developed to provide a much higher level of security then was provided by either previous version. A couple different security features are implemented within the SNMPv3 standard; these include:<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>- Message integrity<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>- Authentication<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>- Encryption</li>
</ul>
Configuring <b>SNMPv3</b> is an improvement over v2c or v1 with added security features such priv (DES, 3DES, AES) and auth (md5 , sha).<br />
<div>
<br />
I created username nagios password stal1148 on the network device (130.30.230.1) for test SNMP V3 on the Nagios monitoring system.<br />

Guideline for request a new vendor or purchase/upgrade new hardware/software with a new vendor. I guide you through a highly effective, tried and tested method which simplifies the process and ultimately helps you make the right choice. There’re main reasons to show why you select some sources in order to support. The vendor status can be approved, unapproved, or inactive if you do not have sufficient reasons. I have presented 3 cases shared and typically help the customers as the following sample:<br />

<strong>Process Impacted</strong><br />
To upgrade lease line link for Site A – Site B connection from 2Mbps to 10Mbps with Verizon MPLS<br />
<strong>Nature and description of Exception</strong><br />
<ol style="text-align: left;">
<li>Thailand use Verizon MPLS @ 2Mbps for point-to-point between Site A and Site B. </li>
<li>Verizon MPLS is biggest Telecom service provider in Thailand (state enterprise company). </li>
<li>Verizon MPLS has provided the good service performance from the past experience. </li>
</ol>
<div>
<strong>Justification</strong></div>
<ol style="text-align: left;">
<li>We select to upgrade this link with Verizon (current vendor) since Verizon is only one Telecom service provider in Thailand and have their own infrastructure in Singapore for MPLS connection.</li>
<li>Upgrade MPLS with current vendor will not impact much in technical change and testing. Also expect for less operation problems for ongoing support.</li>
</ol>
<br />
<strong>Process Impacted</strong><br />
Provide the country wide WAN network service to 12 remote offices around Thailand<br />
<div>
</div>
<div>
<strong>Nature and description of Exception</strong> <strong></strong></div>
<ol style="text-align: left;">
<li>Thailand network infrastructure is provided by a few number of major telecommunication vendors and they own different license depend on technology type of service and coverage area, for example True(Telecom service provider) is expertise on land-line service in Bangkok and nearby cities, True(Telecom service provider) also expand to other major cites too.</li>
<li>Since Our company use the main links from True both HQ office and brach and our company strong require for the highest network availability and True(Telecom service provider) can establish with their partner in the area that True(Telecom service provider) has no service.</li>
<li>True(Telecom service provider) is selected for a single point of contact for our company Wan network service </li>
</ol>
<div>
<strong>Justification</strong></div>
<ol style="text-align: left;">
<li>True(Telecom service provider) is selected because True(Telecom service provider) is the strongest and critical service vendor in Bangkok and our company gateway is in Bangkok area</li>
<li>Even True(Telecom service provider) has no service in some cities but True(Telecom service provider) can make a good partner with other telecommunication vendors and there is no single vendor who can provide WAN service to all cities in Thailand</li>
<li>Thailand network is in the migration process, may be change to other technology and also change IT service group, changing to other vendor will create high impact to business unit operation level. </li>
</ol>
<br />
<strong>Process Impacted</strong><br />
Maintenance service contract to 40 CISCO network equipments and they are critical impact to our company (Thailand) business operation<br />
<div>
</div>
<div>
<strong>Nature and description of Exception</strong> </div>
<ol style="text-align: left;">
<li>Our company apply for a global contract with CISCO and only recommended CISCO device can be use in our company IT infrastructure, purchase price and conditions are agreed from the corporate level.</li>
<li>In Thailand, CISCO recommend for Datacraft (as CISCO’s gold partner distributor) and Datacraft is a big-regional firm in Asia-pacific. </li>
<li>Among of other CISCO’s partner & distributor, Datacraft is better in sale support relation and service performance from the past performance, and I see no critical point to select & compare for new vendor under same global price and service condition (cost is already fixed)</li>
</ol>
<div>
</div>
<div>
<strong>Justification</strong></div>
<ol style="text-align: left;">
<li>Since our company (Thailand) is applied for the regional price so only comparative point is vendor service performance and Datacraft did not show any critical poor service performance from the past</li>
</ol>

<strong>Trick and tip</strong> for network admin you should know when you work on enterprice switch. These commands will help you to work faster. If you know the IP address of the device then try to ping it from within the switch. If the device is pingable, then do a simple <strong>sh ip arp</strong> command. This command will show the <strong>MAC address</strong> of the device. <br />
<br />
TB-CS-4506#<br />
TB-CS-4506#<strong>ping 142.30.15.254 ## Step 1</strong><br />
Type escape sequence to abort.<br />
Sending 5, 100-byte ICMP Echos to 142.30.15.254, timeout is 2 seconds:<br />
!!!!!<br />
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/4/9 ms<br />
<br />
TB-CS-4506#<br />
TB-CS-4506#<strong>sh ip arp 142.30.15.254 ## Step 2</strong><br />
Protocol Address Age (min) Hardware Addr Type Interface<br />
Internet 142.30.15.254 140 <strong>18ef.63dc.aacd</strong> ARPA Vlan20<br />
<br />
Then, do the show mac-address command on the switch. This will show the interface (or IP) to which it is connected to a port or through which it is learned.<br />
<br />

This article will guide your through the steps to enable SNMP in Cisco Routers and Switches including how to apply security as the configuration of the underlying devices. This is to make the devices more secure same as international companies worldwide practice.<br /><br />

<strong>Here's an example:</strong><br />
<ol>
<li>Telnet to the switch/router<br />C:\Users\LAX>telnet THHQCE7-3845</li>
<li>Enter the Enable mode<br />THHQCE7-3845> enable<br />Password:<br />THHQCE7-3845#</li>
<li>Enter Config Mode<br />THHQCE7-3845# configure terminal</li>
<li>Use the command below to add a Read-Only an Read write community string<br />THHQCE7-3845(config)# snmp-server community 14all3$$ RO<br />THHQCE7-3845(config)# snmp-server community gds4chv1 RW</li>
</ol>
<strong>Configuration Examples for snmp-server setting:</strong><br />
snmp-server community 14all3$$ RO 30<br />
snmp-server community gds4chv1 RW 10<br />
snmp-server community mrtg RO 1300<br />

snmp-server host 172.20.71.201 config <br />
snmp-server host 172.20.9.201 config <br />
<br />
<strong>Next</strong>, I highly recommend to configure SNMP in order to make it secure. If you want to secure the communication between network monitoring tool (WhatsUp, Solarwinds, Nagios) and the switches/routers you'll have to use SNMPv3.<br />
<br />
<strong>ACL SNMP setting example;</strong><br />
!<----- ACL 10 for Read Write, ACL 30 for Read Only<br />
!<br />
! ACL 10 – SNMP READ WRITE<br />
!<br />
no access-list 10<br />
access-list 10 permit 172.27.124.18 log<br />
access-list 10 permit 136.171.124.18 log<br />
access-list 10 permit 172.20.71.200 log<br />
access-list 10 permit 172.20.9.200 log<br />
access-list 10 permit 172.20.50.21 log<br />
access-list 10 permit 172.20.46.70 log<br />
access-list 10 deny any log<br />
!<br />
!<br />
! ACL 30 – SNMP READ ONLY<br />
!<br />
no access-list 30<br />
access-list 30 permit 172.20.46.89 log<br />
access-list 30 permit 172.20.46.114 log<br />
access-list 30 permit 172.20.50.22 log<br />
access-list 30 permit 172.20.32.5 log<br />
access-list 30 permit 172.20.46.5 log<br />
access-list 30 permit 172.20.46.6 log<br />
access-list 30 permit 172.20.46.8 log<br />
access-list 30 deny any log<br />
!<br />
<br />
<br />
<strong>Testing:</strong><br />
To test the new configuration use snmpwalk on your linux server running your network monitoring tools<br />

Below is how to set up step by step on Cisco router or Cisco switch;<br />
<ul style="text-align: left;">
<li><strong>Enabling NetFlow</strong><br />Enter global configuration mode on Cisco router or Cisco switch, and issue the following commands for each interface on which you want to enable NetFlow:<br /> #interface {interface} {interface_number} <br /> #ip route-cache flow</li>
<li><strong>Enabling the exports of these flows</strong> <br />Enter global configuration mode on Cisco router or Cisco switch, and issue the following commands by use the IP address of your NetFlow Collector and configured listening port. UDP port 9995 is used for example.<br /> # ip flow-export version 5<br /> # ip flow-export destination <ip_address> 9995<br /> # ip flow-export source Loopback0</li>
<li><strong>Turning off NetFlow</strong><br />Issue the following commands in global configuration mode to stop exporting NetFlow data:<br /> #interface {interface} {interface_number}<br /> #no ip route-cache flow<br />This will disable NetFlow export on the specified interface. Repeat the commands for each interface on which you need to disable NetFlow.</li>
<li><strong>Diagnosis</strong><br />In enable mode you can see current NetFlow configuration and state by looking at the output from <br />
#<strong>sh ip flow export</strong> Shows the current NetFlow configuration<br /> #<strong>show ip cache flow</strong> and <strong>sh ip cache verbose flow</strong> These commands summarize the active flows and give an indication of how much NetFlow data the device is exporting<br /><br /><strong>Note:</strong> <em>When access lists are used, all cisco routers or cisco switch must log failed network access attempts.</em></li>
</ul>

Below configuration were created to provide you a basic understanding of<strong> AAA</strong>; that of which is commonly used in production networks for authentication, authorization and accounting.<br />
<br />
<strong>Step 1:</strong> Create a backup user account<br />
INHQRL2-3845(config)# dcth privilege 15 password datakrub!<br />
<br />
<strong>Step 2:</strong> Enabling AAA<br />
INHQRL2-3845(config)# aaa new-model<br />
<br />
<strong>Step 3:</strong> Configuring the TACACS+ servers<br />
INHQRL2-3845(config)# tacacs-server host 10.1.50.101 key cisco12345<br />
<br />
<strong>Step 4:</strong> Define the AAA method lists<br />
INHQRL2-3845(config)# aaa authentication login default group tacacs+ local<br />
INHQRL2-3845(config)# aaa authorization exec default group tacacs+ local<br />
<br />
<strong>Step 5:</strong> Enforcing AAA authentication on terminal lines<br />
INHQRL2-3845(config)# line console 0<br />
INHQRL2-3845(config-line)# login authentication default<br />
INHQRL2-3845(config)# line vty 0 15<br />
INHQRL2-3845(config-line)# login authentication default<br />

The "<strong>show interfaces link</strong>" command is supported in Catalyst 4500 Series only, this command displays how long a cable has been disconnected from an interface and you can add the modifier known like “include” with the keyword “weeks” #<strong>sh int link | inc week</strong>, you will have more ports released for future connection.. <br />
<br />
As we know this command is not supported in Catalyst 6500 series, 3750 series and 2960 series but you can use the "<strong>sh int | i ther|rial|link|Vlan|ast input</strong>" and "<strong>sh int gi 0/1 | inc ast input</strong>" command that will display the down time for each port instead.

Before being given the opportunity to logon to any Company Cisco network devices, users must be presented with a Login Banner that states whom should be using the system and that monitoring is possible.... it prompt when someone will login into the cisco devices by Telnet and Console that also could be a message for unauthorize accessing of your cisco router, switch and firewall as a notice. So I would like to share How to setup <strong>Login Banner</strong>, <strong>EXEC</strong> & <strong>MOTD Banner</strong>(s) on Cisco Devices(Router, Switch, ASA) including the example...<br />
<br />
<strong>Banner Typical Use</strong><br />
<ul>
<li><strong>Message of the Day (MOTD)</strong> Show before the login prompt. The MOTD banner is displayed on all terminals and is useful for sending messages that affect all users and for temporary messages that may change from time to time, such as “Router1 down for maintenance at midnight.”</li>
<li><strong>Login</strong> Show before the login prompt but after the MOTD banner. For permanent messages such as “Unauthorized Access Prohibited.”</li>
<li><strong>Exec</strong> Shown after the login prompt. Used to supply information that should be hidden from unauthorized users.</li>
</ul>
Let's see how to configure a login benner on Cisco Devices(Router, Switch, ASA)<br />
Switch(config)#banner login {char} {banner text} {char} <br />
For example <br />
Switch(config)#banner login #<br />
Enter TEXT message. End with the character '#'.<br />

This time, I will talk about a<strong> First Hop Redundancy Protocol (FHRP)</strong> that i have already made it as a short note. I could pass CISCO exam because of this so i just would like to share. You can then compare your solution with a suggested solution and apply with your business. Accordingly, you can take advantage of a first-hop redundancy protocol. ... <strong>HSRP, VRRP</strong> and <strong>GLBP</strong> are the main three first hop redundancy protocols. <br />

<tr>
<td bgcolor="#f9f9f9" valign="top" width="112"><strong>Advantages</strong></td>
<td bgcolor="#f9f9f9" valign="top" width="242">• Easy to configure, the protocol does not affect the routing tables or hosts configuration.<br />
<br />
• The traffic increase caused by HSRP is minimal.</td>
<td bgcolor="#f9f9f9" valign="top" width="223">• Simplified network management: Deploying VRRP on multicast and broadcast LANs such as Ethernet, you can ensure that the system can still provide highly reliable default links without changing configurations (such as dynamic routing protocols or route discovery protocols) when a device fails, and prevent network interruption due to a single link failure.<br />
<br />
• High adaptability: A VRRP packet is encapsulated in an IP packet, and supports different kinds of upper layer protocols.<br />
<br />
• Low network overhead: VRRP defines only one packet type, VRRP advertisement, and only the master in a VRRP group can send VRRP advertisements.</td>
<td bgcolor="#f9f9f9" valign="top" width="194">• Efficient use of network resources: multiple paths upstream from the gateways can be utilized simultaneously.<br />
<br />
• Higher availability: GLBP offers enhanced redundancy eliminating single point of failure of the first-hop gateway. An enhanced object-tracking feature can be used with GLBP to ensure the redundancy implementation mirrors network capabilities. This same feature is also available for HSRP and VRRP.<br />
<br />
• Automatic load balancing: Off-net traffic is shared among available gateways on a per-host basis, according to the defined load-balancing algorithm.<br />
<br />
• Lower administration costs: Since all hosts on a subnet can use a common default gateway while load balancing is still achieved, administration of multiple groups and gateways is unnecessary.<br />
<br />
• Simpler Access-layer design: More efficient use of resources is now possible without configuring additional VLANs and subnets.</td>
</tr>
<tr>
<td valign="top" width="112"><strong>Disadvantages</strong></td>
<td valign="top" width="242">• Three second recovery time is hardly acceptable for real time traffic, such as voice over IP traffic.<br />
• HSRP is a weak protocol from the security point of view (see Section 4.5.4).<br />
• HSRP is a Cisco proprietary protocol, while in a free patent protocol, further development is feasible.</td>
<td valign="top" width="223">No security is used, as the offered authentication method is weak.</td>
<td valign="top" width="194">• Cisco proprietary protocol.<br />
• Higher complexity on network management as a result of high number of configurable parameters to take into consideration</td>

- 100% loop-free classless routing</td>
<td valign="top" width="194"> - Minimizes the number of routing table entries<br />
- Contains LSA flooding to a reasonable area<br />
- Each routing device takes a copy of the LSA updates its LSDB and forward the LSA to all neighbor devices within area<br />

- Enforces the concept of a hierarchical network design</td>
<td valign="top" width="194"> - BGP provides the routing betw these autonomouse systems.<br />
- BGP uses the concept of autonomous systems (AS). An autonomous system is a group of networks under a common administration. The Internet Assigned Numbers Authority (IANA) assigns AS numbers: 1 to 64511 are public AS<br />
numbers and 64512 to 65535 are private AS numbers.<br />
- IGP: A routing protocol that exchanges routing infor within AS. RIP, IGRP, OSPF, IS-IS and EIGRP are examples of IFPs.<br />
- EGP: A routing protocol that exchanges routing infor betw different AS. BGP is an example of an EGP.<br />
- The administrative distance for EBGP routes is 20. The administrative distance for IBGP routes is 200.<br />
- BGP neighbors are called peers and must be statically configured.<br />
- BGP uses TCP port 179. BGP peers exchange incremental, triggered route updates and periodic keepalives.</td>

- BGP database, or RIB (Routing Information Base): A list of networks known by BGP, along with their<br />

- <strong>Hello</strong>: Identifies neighbors and serves as a keepalive mechanism sent multicast<br />
- <strong>Update</strong>: Reliably sends route information unicast to a specific router<br />
- <strong>Query</strong>: Reliably requests specific route information query packet multicast to its neighbors<br />
- <strong>Reply</strong>: Reliably responds to a query replies are unicast<br />
- <strong>ACK</strong>: Acknowledgment</td>
<td bgcolor="#F9F9F9" valign="top" width="194">The <strong>5</strong> OSPF packet types follow:<br />
- <strong>Hello</strong>: Identifies neighbors and serves as a keepalive.<br />
- <strong>Link State Request (LSR)</strong>: Request for a Link State Update (LSU). Contains the type of LSU requested and the<br />
ID of the router requesting it.<br />
- <strong>Database Description (DBD)</strong>: A summary of the LSDB, including the RID and sequence number of each LSA<br />
in the LSDB.<br />
- <strong>Link State Update (LSU)</strong>: Contains a full LSA entry. An LSA includes topology information; for example, the<br />
RID of this router and the RID and cost to each neighbor. One LSU can contain multiple LSAs.<br />
- <strong>Link State Acknowledgment (LSAck)</strong>: Acknowledges all other OSPF packets (except Hellos).</td>
<td bgcolor="#F9F9F9" valign="top" width="194">BGP has <strong>4</strong> types of messages:<br />
- <strong>Open</strong>: After a neighbor is configured, BGP sends an open message to try to establish peering with that neighbor.<br />
Includes information such as autonomous system number, router ID, and hold time.<br />
- <strong>Update</strong>: Message used to transfer routing information between peers. Includes new routes, withdrawn routes, and<br />
path attributes.<br />
- <strong>Keepalive</strong>: BGP peers exchange keepalive messages every 60 seconds by default. These keep the peering session<br />
active.<br />
- <strong>Notification</strong>: When a problem occurs that causes a router to end the BGP peering session, a notification message<br />
is sent to the BGP neighbor and the connection is closed.</td>

<td valign="top" width="194">Establishing Neighbors and Exchanging Routes<br />
<strong>Step 1. Down state</strong>: OSPF process not yet started, so no Hellos sent.<br />
<strong>Step 2. Init state</strong>: Router sends Hello packets out all OSPF interfaces.<br />
<strong>Step 3. Two-way state</strong>: Router receives a Hello from another router that contains its own router ID in the neighbor<br />
list. All other required elements match, so routers can become neighbors.<br />
<strong>Step 4. Exstart state</strong>: If routers become adjacent (exchange routes), they determine which one starts the<br />
exchange process.<br />
<strong>Step 5. Exchange state</strong>: Routers exchange DBDs listing the LSAs in their LSD by RID and sequence number.<br />
<strong>Step 6. Loading state</strong>: Each router compares the DBD received to the contents of its LS database. It then sends a<br />
LSR for missing or outdated LSAs. Each router responds to its neighbor’s LSR with a Link State Update.<br />
Each LSU is acknowledged.<br />
<strong>Step 7. Full state</strong>: The LSDB has been synchronized with the adjacent neighbor.</td>
<td valign="top" width="194">BGP Peering States<br />
The command show ip bgp neighbors shows a list of peers and the status of their peering session. This status can<br />
include the following states:<br />
- <strong>Idle</strong>: No peering; router is looking for neighbor. Idle (admin) means that the neighbor relationship has been<br />
administratively shut down.<br />
- <strong>Connect</strong>: TCP handshake completed.<br />
- <strong>OpenSent, or Active</strong>: An open message was sent to try to establish the peering.<br />
- <strong>OpenConfirm</strong>: Router has received a reply to the open message.<br />
- <strong>Established</strong>: Routers have a BGP peering session. This is the desired state.</td>

Benefit of Cisco IP Phone Extension Mobility that serve a user login service allows phone users to temporarily access a physical phone other than their own phone and utilize their personal settings, such as directory number, speed-dial lists, and services, as if the phone is their own desk phone. The phone user can make and receive calls on that phone using the same personal directory number as is on their own desk phone.<br />
<br />
<strong>How to Enable Extension Mobility by perform the following tasks to enable Extension Mobility in Cisco CME:</strong><br />
<em>Before beginning, please note that serious damage can be caused by entering inappropriate commands. Please be careful when altering the configuration of any router.*</em><br />
<em></em><br />
<strong>1. Set up and associate the physical phone.</strong><br />
The easiest way to avoid searching through lines of configuration or hunting an automatically registered phone is to set up the phone association before plugging it in to a switchport on the network. In other words, give the router a "heads up" that the phone is about to be initialized.<br />
THHQRV1-3845# configure terminal<br />
THHQRV1-3845(config)# ephone 1 <em>#Configuration mode for ephone</em> <br />
THHQRV1-3845(config-ephone)# mac-address 11aa.22bb.33cc <em>#The MAC address for the phone</em><br />
THHQRV1-3845(config-ephone)# button 1:5 <em>#Assign buttons to the phone by using the ephone-dn</em> <br />
THHQRV1-3845(config-ephone)# type 7962 <em>#Set the phone type</em><br />
THHQRV1-3845# show ephone ? <em>#Show a list of supported phone types.</em><br />
<br />
<strong>2. Create Voice user profile for Extension Mobility</strong> <br />
<strong>voice logout-profile</strong> To enter voice logout-profile configuration mode to create a logout profile and define the default appearance for a Cisco Unified IP phone enabled for Extension Mobility, use the voice logout-profile command in global configuration mode. To delete an logout profile, use the no form of this command:<br />
THHQRV1-3845# configure terminal<br />
THHQRV1-3845(config)# voice logout-profile 1 <em>#Create logout profile</em><br />
THHQRV1-3845(config-logout-profile)# pin 123456 <em> #Set a PIN to be used by a phone user</em><br />
THHQRV1-3845(config-logout-profile)# user logout password logout<br />
<br />
To configure a <strong>user profile</strong> for a phone user who logs into a Cisco IP phone that is enabled for Extension Mobility, perform the following steps:<br />
THHQRV1-3845# configure terminal<br />
THHQRV1-3845(config)# voice user-profile 1 <br />
THHQRV1-3845(config-user-profile)# user 7222 password 45678 <br />
THHQRV1-3845(config-user-profile)# number 7222 type normal<br />
THHQRV1-3845(config-user-profile)# speed-dial 1 90892046844 label "On Call" <br />
<br />
<strong>3. Creating Directory Numbers</strong><br />
Create an ephone-dn by using the following commands after logging into and enabling your router:<br />
THHQRV1-3845# configure terminal<br />
THHQRV1-3845(config)# ephone-dn 1 dual-line <br />
THHQRV1-3845(config-ephone-dn)# number 7222<br />
THHQRV1-3845(config-ephone-dn)# pickup-group 10 <br />
THHQRV1-3845(config-ephone-dn)# description Sumuscha T <br />
THHQRV1-3845(config-ephone-dn)# name Sumuscha Teesr <br />
THHQRV1-3845(config-ephone-dn)# call-forward busy 7111 <br />
THHQRV1-3845(config-ephone-dn)# call-forward noan 90811711942 timeout 18 <br />
<br />
<strong>4. Check your running configuration.</strong> <br />
You can check your running configuration (ephone-dn, ephone - and other things)<br />
THHQRV1-3845#show running-config<br />
THHQRV1-3845#show run | beg ephone<br /><br />

<strong>Below are some of the VoIP traffic scenario;</strong><br />
<strong>1. HQ Office -> any IP Telephony site:</strong> Since we are on VoIP, traffic will route to available link. In case there will be an outage on Verizon MPLS all traffic including voice will be routed to Brach Office VPN. This might impact a lot on the voice quality because <span style="color: #0c343d;">Internet Link will not guaranteed or priority on VPN.</span> <br />
<br />
<strong> 2. Branch Office -> HQ Office site VoIP call:</strong> In case of link outage between two offices. Voice traffic will reroute to VPN -> MPLS before it reaches the HQ Office PBX. Again <span style="color: #741b47;">no guarantee on voice quality</span> because of the path that it will take.<br />
<br />
<strong>3. Branch Office -> IP Telephony via HQ Office PBX routing:</strong> Outages on either E1 link between two office or Verizon MPLS will “Greatly” impact the quality of voice. Meaning if Branch Office call IP Telephony voice traffic will go to HQ Office, then HQ Office will route call to Branch Office again since MPLS is down, then route to VPN.<br />
<br />

Most of worldwide companies has begun using new telephone sets on a system based on <strong>VoIP</strong>, <strong>Internet Protocol Telephony</strong> (IPT), a method for sending voice over the data network instead of through a separate phone network. <br />
<br />
This new technology, already adopted by a majority of Fortune 500 companies, offers numerous benefits in terms of cost savings, productivity increases and accommodation of future business growth. In the giant companies especially global companies, <strong>VoIP [IP Telephony]</strong> is expected to provide a solution to many current telephony challenges including; capacity limitations, voicemail reliability issues, aging equipment and increasing scarcity of vendor expertise in earlier technologies like PBX.<br />
<br />
I would like to show you the <strong>VoIP</strong> system as a diagram that would be benefit for your business.<br />

I would like to share <strong>Standard Cisco Router Configuration</strong> in order to give readers understand best practices for Standard Cisco Router Configuration.<br />
<br />
I have seen the following issues resulting from a lack of configuration management:<br />
• Inability to determine user impact from network changes <br />
• Increased reactive support issues and lower availability <br />
• Increased time to resolve problems <br />
• Higher network costs due to unused network components<br />
<br />
<strong>Standard Cisco Router Configuration</strong> maintaining configuration management best-practices, you can expect several benefits such as improved network availability and lower costs. These include:<br />
• Lower support costs due to a decrease in reactive support issues. <br />
• Lower network costs due to device, circuit, and user tracking tools and processes that identify unused network components. <br />
• Improved network availability due to a decrease in reactive support costs and improved time to resolve problems. <br />
<br />
I recommend creating standard configurations for each device classification, such as router, LAN switch, WAN switch, Firewal or any other network devices. Global configuration commands apply to all like devices and include parameters such as service commands, IP commands, TACACS commands, vty configuration, banners, SNMP configuration, and Network Time Protocol (NTP) configuration.<br />
<br />
Keep in mind that the output you are about to see might not exactly match to the following. The output basically varies; it highly depends on your router models and features activated or used. However in general, it should look something like this.<br />

<b>Cisco Icons ~ Network Diagram Example.</b> Having been the network business a long time, I would like to pass on a few pointers that I have learned over the years. When drawing a network diagram, think about whether it makes sense to draw a logical or a physical diagram. I would say 90% of the time, a logical diagram is more useful than a physical diagram and I used these icons for drawing diagram network as standard practice. It looks PROFESSIONAL for any organization even it's SME or large size business.<br />
<br />
I have attached an example of a logical network drawing as I did for Giant company. <br />

<br />
<strong>Use Multiple Pages</strong><br />
The number one mistake in many network diagrams is an attempt to convey too much information on one page. Visio allows use of multiple pages just like an Excel workbook with many worksheets, so consider using multiple drawing sheets for different purposes.<br />
<br />
<strong>Make Use of Border Templates</strong><br />
A border template can make your life a little easier by providing a way to track changes to your diagrams. In your template include sections for author name, version number, date, page number, and any other fields that will be useful. Most of the fields can automatically update themselves - more information on that can be found on the <a href="http://office.microsoft.com/en-us/visio-help/creating-text-fields-to-display-information-in-visio-HA001182249.aspx" target="_blank">Microsoft website here</a>.<br /><br />For example, if you want a background page that displays your company logo, or a title block that contains fields such as the creation date of a drawing, subject, Author, Drawing name, Filename, Manager, create these items and assign them to the foreground page. Let us see the example of what are on the visio after creating the Network Diagram Templates:

Fortunately, WLAN technology contains robust security features with viable authentication and encryption mechanisms. A security solution can be designed in a variety of ways, however. This tip provides some best practices for designing effective security architectures.</span> </span><br />

</div><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> We will cover specific design aspects of the <strong>Cisco WLAN</strong> solution utilizing controller-based architectures. These design best practices have been developed over the course of multiple design initiatives with the Cisco solution and primarily from lessons learned from deploying the Cisco solution. Most of the information is related to the Cisco solution, but some of the lessons learned and best practices relate to the process behind deploying the designs. </span><br />
<br />
<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"><strong>User considerations</strong></span><br />
<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> In most organizations, the user community dictates the security architecture. It is not a one-size-fits-all approach. The recommended approach is to identify the user communities that will utilize the WLAN system and design the security accordingly. </span><br />
<br />
<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">As a foundation, the following user communities are a good place to start: </span><br />
<ul><li><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">Employees/visiting employees -- require access to corporate applications and need those applications to be secure </span></li>
<li><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">Contractors -- on site temporarily, but for an extended period of time; require access to some corporate applications (other than just Internet) </span></li>
<li style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">Guests -- need access to Internet only </span></li>

<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> </span><span style="color: #674ea7; font-family: "Trebuchet MS", sans-serif;">This article identifies Multi-Protocol Label Switching (MPLS) technology components, describes their functionality, and illustrates the value they provide in Service Provider environments.</span><br />
<br />
<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> MPLS was initially targeted for Service Provider customers; however, Enterprises have begun to show interest in deploying this technology. This document can apply to large Enterprise customer whose networks resemble Service Provider networks in the following areas:</span><br />
<ul>
<li><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">Size of the network</span></li>
<li><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">Offer "internal services" to different departments within the Enterprise</span></li>
</ul>
<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> MPLS compliments IP technology. It is designed to leverage the intelligence associated with IP Routing, and the Switching paradigm associated with Asynchronous Transfer Mode (ATM). MPLS consists of a Control Plane and a Forwarding Plane. The Control Plane builds what is called a "Forwarding Table," while the Forwarding Plane forwards packets to the appropriate interface (based on the Forwarding Table).</span><br />

</div>
<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> The efficient design of MPLS uses Labels to encapsulate IP packets. A Forwarding Table lists Label Values, which are each associated with determining the outgoing interface for every network prefix. Cisco IOS Software supports two signaling mechanisms to distribute labels: Label Distribution Protocol (LDP) and Resource Reservation Protocol/Traffic Engineering (RSVP / TE).</span><br />

<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">MPLS comprises the following major components:</span><br />
<ol>
<li><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> </span><span style="font-family: "Trebuchet MS", sans-serif;"><span style="color: #674ea7;">MPLS Virtual Private Networks (VPNs)</span></span><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">—provides MPLS-enabled IP networks for Layer 3 and Layer 2 connectivity. Includes two major components:</span><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> 1. Layer 3 VPNs—based on Border Gateway Patrol</span><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> 2. Layer 2 VPNs—Any Transport over MPLS (AToM)</span></li>
<li><span style="font-family: "Trebuchet MS", sans-serif;"><span style="color: #674ea7;">MPLS Traffic Engineering (TE)</span></span><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">— provides an increased utilization of network bandwidth inventory and for protection services</span></li>
<li><span style="font-family: "Trebuchet MS", sans-serif;"><span style="color: #674ea7;">MPLS Quality of Service (QoS)</span></span><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">— buildings upon existing IP QoS mechanisms, and provides preferential treatment to certain types of traffic, based on a QoS attribute (i.e., MPLS EXP).</span></li>
</ol>
<b style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">MPLS VPNs (Layer 3 VPNs)</b><br />
<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> Layer 3 VPNs or BGP VPNs have been the most widely deployed MPLS technology. They use Virtual Routing instances to create a separate routing table for each subscriber, and use BGP to establish peering relations and signal the VPN-associated labels with each of the corresponding Provider Edge (PE) routers. This results in a highly scalable implementation, because core (P) routers have no information about the VPNs.</span><br />
<br />
<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> BGP VPNs are useful when subscribers want Layer 3 connectivity, and would prefer to offload their routing overhead to a Service Provider. This ensures that a variety of Layer 2 interfaces can be used on either side of a VPN. For example, Site A can use an Ethernet interface, while Site B uses an ATM interface; however, Sites A and B are part of a single VPN.</span><br />
<br />

<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">It is relatively simple to implement multiple topologies with router filtering, including a Hub & Spoke or Full Mesh:</span><br />
<ul>
<li><span style="font-family: "Trebuchet MS", sans-serif;"><span style="color: #674ea7;">Hub and Spoke</span></span><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">—central site is configured to "learn" all the routes from the remote sites, while the remote sites are restricted to "learn" routes only from the central site.</span></li>
<li><span style="color: #674ea7; font-family: "Trebuchet MS", sans-serif;">Full Mesh topologies </span><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;">would result in all the sites having the ability to "learn" or import routes from every other site.</span></li>
</ul>
<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> </span><span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> Layer 3 VPNs have been deployed in networks that have as many as—seven hundred PE routers. Service Providers are currently providing up to five hundred VPNs, with each VPN containing as many as one thousand sites. A wide variety of routing protocols are available deploy on the subscriber access link (i.e. CE to PE link). These include Static Routes, BGP, RIP and Open Shortest Path First (OSPF). Most VPNs have been deployed with Static Routes, followed by BGP Routing.</span><br />
<br />
<span style="color: #20124d; font-family: "Trebuchet MS", sans-serif;"> Layer 3 VPNs offer advanced capabilities, including Inter-AS and Carrier Supporting Carrier (CSC). These provide hierarchical VPNs, allowing a Service Provider to provide connectivity across multiple administrative networks. Currently, initial deployments of such functionality are becoming more widespread.</span><br />
