David,
If a neighbor router does not want to receive your multicasts, you prune
that interface. This could be a problem if you are a hub router with a
multipoint interface and more than one listener on that interface. One
neighbor sends you a Leave message and you stop delivering multicasts out
that interface; other listeners would be disrupted.
Solution: add "ip pim nbma-mode" on your multipoint interface so you
recognize each listener by ip address and treat them as if they were on
point-to-point circuits. You won't prune the interface as long as there is
one interested listener.
HTH, Kym
