[c-nsp] IGMP snooping ME6500

[Tim Stevenson]

Ok - if you have mrouter ports being learned, then the upstream 
router should be sending IGMP queries already & IGMP snooping querier 
is not required.

You may want to check the igmp snooping stats & see what type of 
joins etc are being seen on 1/26. Also what is the downstream switch 
doing from a snooping standpoint?

Probably you should just open a case w/TAC to get to the bottom of this one.
