Basically, we were able to make it work, but that was a while ago.  Your

router needs to do CGMP, which means it must be a Cisco, at least I haven't

heard of any other routers that do CGMP.  If you have a mixture of switches,

some doing CGMP and others doing IGMP snooping, you have to be very

careful. Cisco has a white paper or config note on how to make that

situation work.

 

Personally, I liked the idea of CGMP, it had the router making Layer 3

decisions and telling the switchs which end stations wanted which groups. 

But, I really don't think Cisco has continued development of it, so I'm not

sure how well it will works with things like IGMPv3 and SSM.  And, while I

liked the design it still had some problems, which I can't completely

remember.
