Thanks, Brian.
Now, just to be 100% sure, you're saying that on the spoke F/R routers,
nbma-mode isn't needed, but having it there doesn't do any harm. And, as
long as it's configured on the hub F/R router everything's OK. correct?
Also, if a F/R interface has p2m subinterfaces, does it matter whether the
multicast interface commands (ip pim sparse-dense-mode, ip pim nbma-mode)
are configured on the physcial interface or p2m sub-interfaces?
thanks again.
PS: How do manage to keep so much info in your head? It seems like you
never suffer from leaky bucket syndrone. How is that?
