Hi,
OK. Thanks. In my first post above, it’s a querier. But there are still switches between this and the client. Of course I don’t want to send the multicast traffic to every client port there. i.e. on the bridges of the switches IGMP-Snooping=yes and multicast-flood=no. Does this bridge on the switches between clients and router (querier) have to have an IP, or does IGMP snooping work completely without an extra IP on the bridge on the switches?
