I have a need to run Source Specific Multicast (PIM-SSM) over a network

I understand it's only required that the "last hop router" actually be SSM
aware. What's unclear to me however is what the last hop router means.
The one speaking IGMP to receivers.
Does this mean, given the diagram below only the router closest to the
receiver<Router 1> would need to understand a (S,G) join directly from the
host and everyone in the middle wouldn't care -
Correct. The (s,g) joins are identical to ordinary PIM (s,g) joins, and
are processed normally.
Having said that, I've never tested this ;o)
