One more method to solve it is to build the tunnel between R5 and R6.

%D&.: Re: Multicast NBMA question
Taylor,
I also faced exactly same problem. I don't know a way to resolve it.
(tried "static rp address to spoke & auto-rp address to spoke...with
& without pim NBMA mode...with sparse mode )
Problem only clears only if i move RP to Hub. Lets see if anyone can
help us to figure this problem.

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?
