Brian,

I have found some respite.It did not work with the ip route-cache
command on the interfaces in the path. I tried to change the source ip
( while pinging)  to the loopback interface of R5 and i was able to
get replies from R3 and R2 without any problems. Now will have to
troubleshoot the cause of this.

regards
shamin

	Issue the "no ip route-cache" on all interfaces in the transit
path and then look at the output from "debug ip packet" and "debug ip
routing" when you send traffic. Trace the problem on a hop by hop basis
and see what your results are.
