actually earlier i mentioned using ip pim nbma-mode, but now that i re-read
your statement below, i think that since you did the igmp join on an ethernet
port (assuming the ethernet ports on R2 and R3 are linked) the serial
interface should never be used. if you do a show ip route x.x.x.x where
x..x.x.x is R3's loopback address you'll probably find that R2 is using your
ethernet port and not your serial one. i guess having re-thought things
through, have you verified that you have ip pim sparse-mode on both of your
ethernet ports and your loopback?
i've tried to lab this all sorts of ways and
always seem to be able to ping the group address from all 3 routers regardless
of how i seem to set it up. i guess i digress until i see either your
requirement statement or at least your configs.

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
