Does anyone know wether BR100 or BR200 support IGMP snooping as the switches do? Couldn't yet find any docs about that.

sbx,
No, I don't believe so. It doesn't really make a lot of sense for routers.

Remember, routers are boundaries for IGMP anyway, they are not supposed to forward multicasts onto subnets where there are no listeners for that group.

A switch, on the other hand, without any other controls, will blindly copy received multicasts out all other ports multiplying the consumed bandwidth. Having the ability to glean group membership from the join requests and then restricting where the forwarding occurs to only segments where there are listeners can substantially reduce that multiplication of consumed bandwidth.
