Easy RIPv2 Question

card51short · ‎12-07-2017

Does anyone know why I can't get RouterA to broadcast 192.168.0.0 through RIP? I set it up on RouterB and RouterC and both those networks can ping each other but neither of them can ping RouterA's network. When I do show ip router on A, it doesn't show any of the routes I'm trying to broadcast. Why is this?

Attached is a Word file detailing the network diagram.
Here are my show IP routes from each router :

Router A

172.168.0.0/16 is variably subnetted, 2 subnets, 2 masks

C 172.168.0.0/16 is directly connected, Serial0/1/0

L 172.168.1.2/32 is directly connected, Serial0/1/0

R 172.169.0.0/16 [120/1] via 172.168.1.1, 00:00:00, Serial0/1/0

R 192.168.2.0/24 [120/1] via 172.168.1.1, 00:00:00, Serial0/1/0

R 192.168.3.0/24 [120/2] via 172.168.1.1, 00:00:00, Serial0/1/0

Router B

172.168.0.0/16 is variably subnetted, 2 subnets, 2 masks

C 172.168.0.0/16 is directly connected, Serial0/1/0

L 172.168.1.1/32 is directly connected, Serial0/1/0

172.169.0.0/16 is variably subnetted, 2 subnets, 2 masks

C 172.169.0.0/16 is directly connected, Serial0/1/1

L 172.169.1.2/32 is directly connected, Serial0/1/1

192.168.2.0/24 is variably subnetted, 2 subnets, 2 masks

C 192.168.2.0/24 is directly connected, GigabitEthernet0/0

L 192.168.2.1/32 is directly connected, GigabitEthernet0/0

R 192.168.3.0/24 [120/1] via 172.169.1.1, 00:00:10, Serial0/1/1

Router C

R 172.168.0.0/16 [120/1] via 172.169.1.2, 00:00:07, Serial0/1/0

172.169.0.0/16 is variably subnetted, 2 subnets, 2 masks

C 172.169.0.0/16 is directly connected, Serial0/1/0

L 172.169.1.1/32 is directly connected, Serial0/1/0

R 192.168.2.0/24 [120/1] via 172.169.1.2, 00:00:07, Serial0/1/0

192.168.3.0/24 is variably subnetted, 2 subnets, 2 masks

C 192.168.3.0/24 is directly connected, GigabitEthernet0/0

L 192.168.3.1/32 is directly connected, GigabitEthernet0/0

Hello

Make sure autos-summerisation is disabled on all rtrs, and they are running the same rip version also, once you've done that clear the route table a couple of time and check again.

router rip
ver 2
no auto-summary

clear ip route *

Lastly also post- sh ip protocols

Hello,

on your router A, the routing table does not show interface FastEthernet0 as connected. Make sure that interface is not in 'shutdown' state. If it is up and something is connected, the routing table should show an entry like below (in bold):

Router A

172.168.0.0/16 is variably subnetted, 2 subnets, 2 masks

C 192.168.1.0/24 is directly connected, FastEthernet0/0
L 192.168.1.1/32 is directly connected, FastEthernet0/0
C 172.168.0.0/16 is directly connected, Serial0/1/0
L 172.168.1.2/32 is directly connected, Serial0/1/0
R 172.169.0.0/16 [120/1] via 172.168.1.1, 00:00:00, Serial0/1/0
R 192.168.2.0/24 [120/1] via 172.168.1.1, 00:00:00, Serial0/1/0
R 192.168.3.0/24 [120/2] via 172.168.1.1, 00:00:00, Serial0/1/0

Also, in your drawing, the LAN interfaces are marked as FastEthernet, in your routing table output, they are listed as GigabitEthernet interfaces, make sure you configure the correct interfaces...

I got it guys - I had RouterA's interface plugged into Gig0/1 not Gig0/0.

Thanks!
