All things related to multicast

[Peter John Hill <>]

Hello,

I believe that BSR with redundant RPs takes a bit of time (3 minutes) 
to converge if your RP fails. With the nature of Anycast, you can 
converge as fast as your IGP. I think that is the main difference. It 
won't kill flows that are already on the shortest path (unless the RP 
was on the shortest path), it just keeps new flows from being started 
and shared tree flows, which will still be going through the RP.

Please correct me if I am wrong.
