your frame switching is kind of confusing..your using the same dlci number for
two routers...I suppose it may work, but I used
different dlci's for my routers in the frame switch...
do a 'sh frame-relay map' and see what is mapped to the dlci's..

Subject: Frame-relay / IP assistance
I am having a problem with my Frame-relay set up and I think Ibm just
missing some little thing that I continually overlook, hope you guys can
help me. I have a lab set up with a frame-relay switch going to 4
routers, I will only deal with 2 to keep this as short as possible. I
can not ping any interfaces in this lab, but I can show cdp neighbors
and see all the neighbors, show cdp neighbors detail and see their IP
addresses and my show frame-relay pvc looks good toob&here is the output
of R1bs show frame-relay PVC:

Here is the show cdp neighbors detail command on that same
router for the R3 router:
