based on these symptoms, i'd say you probably need ip pim nbma-mode on R2 so
that it can communicate with the RP before coming back to itself...weird how
that whole process works. once you apply it, if you haven't already, it may
take a minute before pings will go through.
also verify that a routing
protocol is running on your devices so that they'll know how to get to your
hub's loopback address as i mentioned earlier.

Subject: Multicast over FR
I am having a issue with
Multicast. There is a frame-realy could between R1 R2
and R3. R3 is hub here.
configured the spare-mode on all the three router
including the ethernet
port. R3 loopback is configured as RP and R3 is also
mapping agent. Question
has asked to configure the join group 224.1.1.1 on
ethernet port of R2 router.
I am using the nbma mode on R3. I can ping 224.1.1.1 from R1 and R3 but not
able to ping from R2 itself. on R2 RP maping show correctly. What could be the
issue here.
Thanks
