Hi Cisco-addicted,
I am wondering why/how you have a clock rate set on R2?
Can you get the frame-relay map output from all the three switches? Before
doubting an IOS bug or FR switch, see if you can ping by eigrp multicast
address and see who actually replies. Else try out forming unicast
neighbours.
Regards,
Shine

Dears,
Thnaks for your help, I tried & worked on all the comments and notes you
provided but nothing happened.
Dear Jonathan,
I tried the troubleshooting chart and all the ping working fine with me
from everywhere to everywhere with different packet size.
Gangs, do you think it is related to IOS bug??? Or how to isolate any
failure in FR?? I am afraid that the FRSW is responsible for that.
Check the configuration in the R2 (the hub) and R1 & R2 the spokes and I am
waiting for your feedback.

Hi all,
I think maybe there two causes:
1. split-horizon
2. duplicate router-id at EIGRP process.
