Lets check the routing table of R1 for RIP version 2 routes:

R1#show ip route rip

R    192.168.24.0/24 [120/1] via 192.168.12.2, 00:00:14, FastEthernet0/0

R    192.168.34.0/24 [120/1] via 192.168.13.3, 00:00:03, FastEthernet0/1

     192.168.0.0/32 is subnetted, 4 subnets

R       192.168.0.2 [120/1] via 192.168.12.2, 00:00:14, FastEthernet0/0

R       192.168.0.3 [120/1] via 192.168.13.3, 00:00:03, FastEthernet0/1

R       192.168.0.4 [120/2] via 192.168.13.3, 00:00:03, FastEthernet0/1

                    [120/2] via 192.168.12.2, 00:00:14, FastEthernet0/0

Since we have configured basic RIP version 2 with no additional features, all timer, filters etc are stay as default:

R1#show ip protocols

Routing Protocol is "rip"

  Outgoing update filter list for all interfaces is not set

  Incoming update filter list for all interfaces is not set

  Sending updates every 30 seconds, next due in 27 seconds

  Invalid after 180 seconds, hold down 180, flushed after 240

  Redistributing: rip

  Default version control: send version 2, receive version 2

    Interface             Send  Recv  Triggered RIP  Key-chain

    FastEthernet0/0       2     2                                    

    FastEthernet0/1       2     2                                   

    Loopback0             2     2                                   

  Automatic network summarization is not in effect

  Maximum path: 4

  Routing for Networks:

    192.168.0.0

    192.168.12.0

    192.168.13.0

  Routing Information Sources:

    Gateway         Distance      Last Update

    192.168.13.3         120      00:00:14

    192.168.12.2         120      00:00:27

  Distance: (default is 120)

Lets debug the RIP version 2 packets:

R1#debug ip rip

RIP protocol debugging is on

Lets test the reachability:

R1#ping 192.168.0.4 source 192.168.0.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.0.4, timeout is 2 seconds:

Packet sent with a source address of 192.168.0.1

Success rate is 100 percent (5/5), round-trip min/avg/max = 60/72/92 ms
