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
