CCNA4 case study

Hi guys,

I am working on the CCNA 4 WAN case study.
I almost have it all working after reading a post on this site about rip redistribution which helped alot.
The problem is that the cork router does not know how to get to the limerick router.
A route to the limerick router does not appear in the routing table for the cork router.
I can get to every other part of the network and the frame-relay connection between cork and Galway works fine. I added the correct network statement to the limerick router but cork doesn’t know where it is.
Other than that everything works fine.


Below are each router's config
I left out the frame-relay switch, as everything there seems fine.

Any help would be great


Here is a link i found to the case study

    I just checked and the cork router IOS is version 12.3 and all the others are version 12.0.
    Could this cause the problem.

    Nathan,
    Are the configs you posted complete? Where is the OSPF configuration for the Belfast router? Also, why is the default route on the Cork router pointing toward Galway rather than Belfast and the Internet?
