Ben,
The neighbor is directly connected neighbor. I am able to ping neighbor
address and loopback address of RP.
Regards,
Milind

This problem manifests when the AutoRP discovery messages do not arrive
on the RPF interface, probably due to a divergence in the muticast path
from the unicast path.
Solution: ip mroute command
Alternative: Tune your IGP for change the routers next hop to the
Mapping Agent, and multicast source.
