Step in configuring router A
Router>enable
Router#configure terminal
Router(config)#hostname RA
RouterA(config)#interface fa0/0
RouterA(config-if)#ip address 192.168.1.1 255.255.255.192
RouterA(config-if)#no shut
RouterA(config)#interface s0/0
RouterA(config-if)#ip address 192.168.1.97 255.255.255.252
RouterA(config-if)#no shut
RouterA(config-if)#clockrate 64000
RouterA(config-if)#exit
RouterA(config)#router rip
RouterA(config-router)#version 2
RouterA(config-router)#network 192.168.1.0
RouterA(config-router)#network 192.168.1.96
Step in configuring router B
Router>enable
Router#configure terminal
Router(config)#hostname RB
RouterB(config)#interface fa0/0
RouterB(config-if)#ip address 192.168.1.65 255.255.255.224

RouterB(config-if)#ip address 192.168.1.98 255.255.255.252
RouterB(config-if)#no shut
RouterB(config-if)#exit
RouterB(config)#router rip
RouterB(config-router)#version 2
RouterB(config-router)#network 192.168.1.64
RouterB(config-router)#network 192.168.1.96
