Re: about MULTICAST TUNNELS

Rameez,

Who performs the RPF check? Sender or Receiver?

If RB is receiving the traffic across the tunnel, RB needs the mroute (it is
performing the RPF check). If the routers have a PIM adjacency over the
tunnel, RB sends PIM joins through the tunnel causing RA to populate the
outgoing interface list with the tunnel interface. RB receives traffic
encapsulated in the tunnel and therefore needs the mroute. Do a quick lab
:-)
