EIGRP Routing

EIGRP (Enhanced Interface Gateway Routing Protocol)

1.   It is Dynamic Routing Protocol

      2.   It is also known as hybrid Protocol combine and Border Gateway Protocol

      3.   EIGRP is classless Routing protocol and support CIDR network

      4.   EIGRP use Autonomous no. system (as) range 1 to 65535

     5.   Autonomous no. must same between two router

           EIGRP support 255 networks 

Now Configure EIGRP Dynamic Routing

       Basic Configuration And Clock Rate

First router(2621-XM) and add port(WIC-2T) and Follow this Diagram

Go to first router in cli mode and type

          No

          Router>en

          Router#conf t

          Router(config)#int s0/0

          Router(config-if)#ip address 192.168.30.1 255.255.255.0

          Router(config-if)#no shut

          Router(config-if)#clock rate 64000

          Router(config-if)#exit

          Router(config)#int f0/0
   Router(config-if)#ip address 192.168.10.1 255.255.255.0
   Router(config-if)#no shut

          Router(config-if)#exit

Go to second router in cli mode

          No

          Router>en

          Router#conf t

          Router(config)#int s0/0

          Router(config-if)#ip address 192.168.30.2 255.255.255.0

          Router(config-if)#no shut

          Router(config-if)#exit

          Router(config)#int s0/1

          Router(config-if)#ip address 192.168.40.1 255.255.255.0

          Router(config-if)#no shut

          Router(config-if)#clock rate 64000

          Router(config-if)#exit

          Router(config)#int f0/0

          Router(config-if)#ip address 192.168.20.1 255.255.255.0

          Router(config-if)#no shut

          Router(config-if)#exit

Go to Third router in cli mode

          No

    Router>en

          Router#conf t

    Router(config)#int s0/0

          Router(config-if)#ip address 192.168.40.2 255.255.255.0

          Router(config-if)#no shut

          Router(config-if)#exit

          Router(config)#int f0/0

          Router(config-if)#ip address 192.168.50.1 255.255.255.0

          Router(config-if)#no shut

          Router(config-if)#exit

Step 2 Routing  

In First Router

First check network in (Router# Show ip route)

Then type

Router#conf t

Router(config)#router eigrp 10

Router(config-router)#network 192.168.10.0

Router(config-router)#network 192.168.30.0

In Second router

Router# Show ip route

Router#conf t

Router(config)#router eigrp 10

Router(config-router)#network 192.168.20.0

Router(config-router)#network 192.168.30.0

Router(config-router)#network 192.168.40.0

In Third router

Router# Show ip route

Router#conf t

Router(config)#router eigrp 10

Router(config-router)#network 192.168.40.0

Router(config-router)#network 192.168.50.0

To check Send Packet's Between Networks or ping from fist router to all ip's as shown in picture
