Hi,
My 3500XL access switchs dont see the multicast router. CGMP is enable on my distribution 6500. I've got a aggregation layer of stacked 3750G-12S between the distribution and the access layer. Could the 3750 be dropping the 0100.0cdd.dddd (CGMP join) packet ?

Looks like the 3750 is dropping the packets
When I issue
sh platform forward g1/0/2 00d0.03ff.2000 0100.0cdd.dddd
There is no output interface for my packet. G1/0/2 is the router...
