I am trying to test a multicast config as shown below
R1 ser 0/0
/ \
/ \
R2 ser 0/0.1 R3 ser 0/0.1
I am running IP PIM sparse-dense mode and I have R1 as the mapping
agent and R2 and R3 as the RP for different multicast ranges. To test
this configuration I am trying to have R3 join a multicast group that
it is the RP for. The problem is that R1 and R2 are not getting an
mroute for it. It looks like the mapping agent R1 is mapping the
multicast group to R2 and R3 properly but the mroute is not getting
installed in the table. can someone please point me in the right
direction ?
Thanks,
Mike F.
