Hi Aamir,
If your outgoing interface list is null, then I would first ask whether the
group is being destributed in Dense Mode or in Sparse Mode. You can easily
tell by looking for the D or S flag on the the of the first line of the (*,G)
entry.
If you are doing Dense Mode and the OILIST is null, then that means you have
no PIM neighbors and you have no connected clients. Check your configuration:
for example, show ip pim neighbors.
If you are doing Sparse Mode and your OILIST is null, then it means you have
not recieved an IGMP or PIM join on any interface. Check that downstream
routers have clients and know how to reach the RP.
HTH,
