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?

Hello, Ben.
Please write a diagram will all the addresses assigned per interface.
I guess you will find the first issue.
Second one is that RIP is not enabled on all the interfaces ( CORE:s0/1/0, CORE s0/3/1).
If you are just learning RIP, then use command network 0.0.0.0
03-03-2014 02:48 PM
I issued the network 0.0.0.0 command and rip routes are still not being advertised. And how exactly do you enable rip on specific interfaces?

Does the core device have reachablilty to both Richmond and Eire over its physical interfaces?
Also disable Automatic network summarization.

Ben,
For starts, I would suggest doing 'no auto' under the RIP routing process at the hub.
Erie
-----
!
interface Serial0/3/0
ip address 199.122.20.10 255.255.255.248
encapsulation ppp
!
I see that interface, as the only interface configured, with an IP address on that router, yet under RIP I see the following.
!
router rip
version 2
network 189.12.0.0
network 195.131.50.0
network 199.122.20.0
network 203.167.10.0
network 212.2.40.0
no auto-summary

I don't think the networks advertisd in bold really need to be advertised...
Richmond

Same thing as Erie, I see the following interface, as the only interface configured with an IP address.
!
interface Serial0/3/0
ip address 195.131.50.10 255.255.255.248
encapsulation ppp
But under RIP you are advertising all the networks.

First off...Thank You guys.
I made the changes both of you explained but i still cannot get these router to see one another.
PDriver - yes the core router can see both the erie and richmond routers.

Assuming the core router can ping each of the other routers can you post -
1) "sh ip route" from all routers
2) RIP config from each router (not the whole config just the router bit if you can)

and just so you guys know...there are other routers on this network and rip is not working for any of them. I just figured to use 3 instead of all of them to make it easier to troubleshoot. once I find the fix I will apply to the remaining routers
03-03-2014 04:25 PM

Okay, sorry but can you actually post the "sh run" for all three devices and attach them as you did in your original post.
Can you ping from the core router to each of the other routers ?
Jon

Sorry Jon. The configs are below. Also yes I can ping all routers from the Core router.

On the core router you need to add network statements under your RIP config for the networks used to connect to the other two routers.
Jon
03-03-2014 04:53 PM
Jon,
I agree.
Ben if you look at the below config, you have network statements setup previously for your RIP networks on your CORE router.
!
router rip
version 2
network 189.12.0.0
network 195.131.20.0
network 199.122.20.0
network 203.167.10.0
network 212.2.40.0
!
For the two spokes to come up Erie and Richmond, you need to add the following.
network 199.122.20.0
network 195.131.50.0
The others you don't technically have to add, if the're are no routers running RIP connected to them, but if you want reachability for those networks within RIP, you will need to add those network commands as well.
*I was just joking with you pdriver. I was thinking when I was typing all that above, I bet someone is doing the same thing as me haha*
