All things related to multicast

[Marshall Eubanks <>]

Dear Greg;

   Precisely. I looked at the protocol in depth and concluded that if
you are running PIM-SM, plus MSDP or SSM, ALL interdomian traffic is (S,G) 
only.
This really simplyfies a PIM snooping switch.

   If I am wrong in this, I would like to hear about it.
