How to perform configuration and convergence between RIP and IGRP protocols?

 

 

 

In this case, we will try to configure two different types of routing protocol (RIP and IGRP) and then perform the convergence between them.

Follow the network topology of three different class network in given figure:

First check the router A status before RIP configuration and convergence.

RouterA#show ip route

C         20.0.0.0/8 is directly connected, serial0/0

C         210.100.10.0/24 is directly connected, loopback0

 

Configure RIP on Router A

RouterA#configure terminal

RouterA#(config)#router rip

RouterA#(config-router)#network 20.0.0.0

RouterA#(config-router)#network 210.100.10.0

RouterA#(config-router)#redistribute igrp 1 metric 1

RouterA#(config-router)#exit 

First check the router B status before IGRP configuration and convergence.

RouterB#show ip route

C         20.0.0.0/8 is directly connected, serial0/0

C        30.0.0.0/8 is directly connected, serial0/1

C        210.100.20.0/24 is directly connected, loopback0

Configuration to Enable IGRP on Router B

In global configuration Mode:

RouterB (config) # router igrp 1 

(Enable IGRP protocol and 1 is Autonomous number)

RouterB (config-router) # network 20.0.0.0 

(Advertised router B Serial Network 20.0.0.0)

vB (config-router) # network 30.0.0.0 

(Advertised router B Serial Network 30.0.0.0)

RouterB (config-router) # network 210.100.20.0

(Advertised router B Ethernet Network 210.100.20.0)

RouterB (config-router) # redistribute rip metric 1 1 1 1 1

RouterB#(config-router)#exit

First check the router C status before RIP configuration.

RouterC#show ip route

C         30.0.0.0/8 is directly connected, serial0/1

C         210.100.30.0/24 is directly connected, loopback0

Configure RIP on Router C

RouterC#configure terminal

RouterC#(config)#router rip

RouterC#(config-router)#network 30.0.0.0

RouterC#(config-router)#network 210.100.30.0

RouterC#(config-router)#exit

Now verify the result on all routers after convergence.

First check on router A

RouterA#show ip route

C    20.0.0.0/8 is directly connected, Serial0

I     30.0.0.0/8 [100/10476] via 20.1.1.2, 00:01:03, Serial0

C    210.100.10.0/24 is directly connected, Ethernet0

I    210.100.20.0/24 [100/8576] via 20.1.1.2, 00:01:03, Serial0

I    210.100.30.0/24 [100/10002001] via 20.1.1.2, 00:01:03, Serial0

RouterB#show ip route

C    20.0.0.0/8 is directly connected, Serial0

C   30.0.0.0/8 is directly connected, Serial1

C    210.100.20.0/24 is directly connected, Ethernet0

I    210.100.10.0/24 [100/3100] via 20.1.1.1, 00:01:03, Serial0

R   210.100.30.0/24 [120/1] via 30.1.1.2, 00:01:03, Serial0

RouterC#show ip route 

R    20.0.0.0/8 [120/1] via 30.1.1.1, 00:00:08, Serial1

C    30.0.0.0/8 is directly connected, Serial1

R    210.100.10.0/24 [120/1] via 30.1.1.1, 00:00:08, Serial1

R    210.100.20.0/24 [120/1] via 30.1.1.1, 00:00:08, Serial1

C    210.100.30.0/24 is directly connected, Ethernet0
