Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need which IP multicast transmission.

To return whether it is the spanning-tree root or not. Step 2: Enable IGMP Snooping in “Multicast-IGMP Snooping-Snooping Config” IGMP snooping is designed to prevent hosts on a local network from receiving traffic for a multicast group they have not explicitly joined. VLAN ID range is 1 to 1001 and 1006 to 4094. If the Snoopers do not require any configuration because snooping is enabled by default on Allied Telesis routers and managed layer 3 switches.
