RIP Routing not advertising

[benschultheis1]

I am trying to get RIP Routing to advertise between 3 routers. I think my configuration ois correct but I am not sure. I am a beginner to the network world and have been checking out other threads but nothing seems to be helping. I am attaching my configs along with outputs from some commands. Can someone please steer me in the right direction?

I orignially had that in there. OK so I added the network statements to  the core router. Now the Richmond router can see the Erie router but not  the other way around.

Ben,

SO the Richmond router can see the Erie router, but the Erire router cannot see the Richmond Router?

Can you post the 'router rip' commands for the Erie router?

It's all getting a bit confusing because you posted the config for Baltimore not Erie when you last posted the configs.

You need to recheck your network statements on each router. The network statement under RIP must match the network used on the interface to connect to the other router.

So John suggested using 199.122.20.0 as one entry but you have no interface on the core router with that subnet. You do have an interface using 199.122.10.0 network (or more specifically 199.122.10.8/29 but you can use the whole subnet - up to you).

But checking the Erie config from your original post it has an interface in the 199.122.20.0 network.

Assuming these are the interfaces connecting the core router to Erie they should be from the same network but they aren't.

Ben,

This config should do the trick, also on one of your spoke router, you do not have "version 2" under your RIP configuration.

Richmond
-------------
interface Serial0/3/0
ip address 195.131.50.10 255.255.255.248

router rip
version 2
network 195.131.50.0
no auto-summary

Baltimore
-------------
interface Serial0/3/0
ip address 212.4.40.10 255.255.255.248

router rip
version 2
network 212.2.40.0
no auto-summary

Core
-------
router rip
version 2
no auto
network 203.167.10.0
network 195.131.50.0
network 212.2.40.0
network 189.12.30.0
network 199.122.10.0

Yeah i screwed that one up. Baltimore is just another router on the network. And I did find the ip addressing error and corrected it. Bit it still isn't working.

Can you post the results of ' show IP route' and 'debug IP rip' on the spoke having issues
