You can use a tunnel for this. Basically the multicast packet will not be
sent out the same interface as received on. Use a tunnel from R1 to R5 or R3
and this changes the logical interface that the packet is received or sent
on.

Subject: Multicast NBMA question
Hi All,
I faced a problem on the multicast NBMA. The R1 is the Hub , R5, R6 are the
spoke.
R1 S0/0 --- R2 and others
|
| |
| NMBA |
s0/0 S0/0
Ether - R5 ( RP) R6--- Ether (225.1.1.1)
If one Spoke ( R5 in this case) is RP and the group member is in another
spoke( R6, e.g) , the RP can't receive the join message. I notice from the
R6 that the PIMv2 join message was sent to the S0/0 ip addresss of R5, but
R5 never get it. The PIM NBMA mode can't help. I guess R1 doesn't forword
the PIMv2 packet to R5 correctly. Anyone have the idea?
Thanks,
Taylor
