RIP - Basic

Topology

Ip Address :
R1 :
    Serial0/0             : 12.12.12.1/24
    FastEthernet0/0  : 13.13.13.1/24
    Loopback0         : 11.11.11.11/32


R2 :
    Serial0/0             : 12.12.12.2/24
    Serial0/1             : 23.23.23.2/24
    Loopback0         : 22.22.22.22/32


R3 :
    Serial0/1             : 23.23.23.3/24
    FastEthernet0/0  : 13.13.13.3/24
    Loopback0         : 33.33.33.33/32


Task :
Configure RIP routing on each router and advertise all interfaces.

Solution :

R1 :

router rip
network 11.0.0.0
network 12.0.0.0
network 13.0.0.0

 R2 :

router rip
network 12.0.0.0
network 22.0.0.0

R3 :

router rip
network 13.0.0.0
network 23.0.0.0
network 33.0.0.0

Verification :
Check the neighbor's route information in all router with command "show ip route rip" and "show ip rip database".
