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
