Need help with RIP issue- spokes not talking

[Wabbit___]

Hello,

I have a hub and spoke router setup, and for some reason, the edge routers are not able to communicate with each other.

R1 (10.0.1.1) is the hub and connects by frame relay to the remote sites (10.0.1.x).

Each remote site has an ethernet interface to the network 192.168.x.1. The hub router also has an ethernet interface to the 192 network (192.168.1.1).

I kind of dropped into this spot to look at router configs that had been done by someone I never met, so I don't know what I might have goofed up. We added a non-Cisco router to the network, so I had to change the routing protocol from EIGRP to RIP v2.

For instance, I SSH into 10.0.1.8 and into 10.0.1.20. Neither can ping the other, though they can still ping the hub. The router shows the route for the devices, though.

Here is the routing table for R8:

Any help is greatly appreciated!

I have looked at the config that you posted. I do not see anything in it that would get around the issue of router to router ping without multiple Frame Relay map commands. I would assume that it has always not worked (and people just did not realize that it did not work). This would not impact the functionality of the network traffic going LAN to LAN but only impacts spoke router to spoke router traffic.

[edit] thank you for using the rating system to indicate that your issue was resolved (and thanks for the ratings). It makes the forum more useful when people can read about issues and can know that there were responses which did lead to a solution of the issue.

The forum is an excellent place to learn about Cisco networking. I encourage you to continue your participation in the forum.
