This line should let R2 ping R2......

Do you have a frame relay map statement with the correct IP address for R3 configured on R2?

kryolla

I can give you the answer but try debug frame packet and it will show you the issue

Lookie here:

R2

interface Serial0/0
ip address 172.12.123.2 255.255.255.0
encapsulation frame-relay
frame-relay map ip 172.12.123.1 221 broadcast
frame-relay map ip 172.12.123.[b]2[/b] 221 broadcast

Typo?
