Prerequisites: CCNP level skills.

Task1
R5 joined the RIP domain but is running RIPv1. It advertises 192.168.5.0 network. Configure routers so R5 receives all the prefixes from the other routers. All other routers should receive 192.168.5.0.

R5 Current Configuration:
!
router rip
 network 10.0.0.0
 network 192.168.5.0
!

Pic. 2 - R5's RIP Details.
Notice!
R5 is running RIPv1 and can receive updates from both RIPv1 and RIPv2 (any version). That's why it installs all the routes sent by R3 (below).

Pic. 3 - R5's Routing Table.
R3 Rejects advertisement from R3 (192.168.5.0) since it is not RIPv2 update.

Pic. 4 - Debug on R3.

Lab Solution

Task1
R5 joined the RIP domain but is running RIPv1. It advertises 192.168.5.0 network. Configure routers so R5 receives all the prefixes from the other routers. All other routers should receive 192.168.5.0.

R3 Configuration:
!
interface FastEthernet1/0
 ip address 10.1.35.3 255.255.255.0
 ip rip receive version 1
!


Notice!
RIPv2 can send or receive RIPv1 updates using the interface commands:
(config-if)#ip rip send version 1
(config-if)#ip rip receive version 1

Verification:
