Michael,
CGMP does not have a concept of the multicast source (unlike the
multicast routing protocol) and therefore the fact that the source is on
the same link as the router should not change standard CGMP operation --
associating the CAM table with the various multicast groups.

No offence, but that answer doesn't remove the quandary
the router regarding which ports should receive the
multicast flow. Hopefully someone can confirm that.

Of course this would depend on if the multicast server and the

Nigel, Thanks, Yes the switch and users are all on the same VLAN. PIM and
IGMP
are working fine across the router and into other CGMP enable switches.
The thing I was not sure of, was: if I have a server multicasting

Of course this would depend on if the multicast server and the

Routers by default will not forward multicast traffic. However, if you
