Hi Brian,
That's fine, but one question arises what about the groups those are
actually forwarding multicast traffic for; we don't have RP for them and
IP pim auto RP listener command has not been entered there for learning
RP for those groups.
Like we have configured
Ip pim rp address 150.1.2.2 1
access-list 1 permit 224.0.1.39
access-list 1 permit 224.0.1.40
We have assigned RP for only these 2 groups on every Router but what
about group 224.1.1.1 that SW2 has joined; we don't have RP for this
group or how shall we learn the RP for this group without either
Sparse-dense mode or ip pim autorp listner.
May be I am missing something here, please clarify..
Thanks
Gops

You need to force the 224.0.1.39 and 224.0.1.40 groups to be sparse in
order to be forwarded via NBMA mode. To do this you need to define a
default RP that is used just for those two groups, i.e.:
ip pim rp-address 1.2.3.4 1
access-list 1 permit 224.0.1.39
access-list 1 permit 224.0.1.40
