RE: sink RP...

I don't believe I've heard the term "sink RP". What are you trying to
accomplish?

Subject: sink RP...

Is it necessary to filter 224.0.1.39 and .40 when configuring a sink RP? I
came across this in a practice lab and didn't do this, but my RP mapping
(using auto-rp) still showed up okay:

R1#sh ip pim rp map
PIM Group-to-RP Mappings

Group(s) 225.0.144.1/32
  RP 2.2.2.2 (?), v2v1, bidir
