I am trying to simulate a Frame Relay topology on a NBMA network.
I am posting the details of sh Running config, sh Frame-relay Map, sh ip int brief, show ip route and ping result of all three routers. Could any one please give me any idea, why East router cant ping west router. Show ip route is showing all the routes properly.

Hi,
You have a Hub and spoke topology so you also need to put a frame-relay map statement for the other spoke on each spoke:
on EAST: frame-relay map ip 172.16.124.3 201 broadcast
on WEST: frame-relay map ip 172.16.124.2 301 broadcast
with these 2 your pings will work.
Regards.
Alain.
