Unexpected Frame-Relay results

Hello all,

I have a simple home lab with a simple WAN connection going through a 2522 acting as a Frame Relay switch. I have managed in the past to get full connectivity but am unable to recreate it now. Please can you show me where I might be going wrong.

Unexpected Frame-Relay results

Mark,

It looks like s0/0 is shut on R2...

HTH,

I believe that John has correctly identified the most serious problem as being that R2 has shutdown on the interface. I also notice that R1 the interface shows as line is down and line protocol is down. Usually that indicates a basic lack of connectivity on the interface and would reflect the connection from R1 to the frame relay switch. I am not sure that it would be caused by the problem on R2. After you fix the problem with shutdown on R2 I suggest that you check the interface on R1 again and if it is still down/down then you have additional troubleshooting to do.
