[c-nsp] multicast on layer 2

[Andrew K Ho]

Howevever, sources do send membership reports.  I'm thrown off by the fact 
that the multicast session never goes past the first hop router, hence, 
there should be no need for the router to participate in the multicast 
session.

Sources do not register - they just send packets.  Routers attached
to the source register at the PIM RP, but this is independent of 
directly attached receivers.
