•IGMP Snooping: IGMP Snooping: Internet Group Management Protocol (IGMP) snooping is a method by which Layer 2 devices can “listen in” on IGMP conversations between hosts and routers. When a switch hears a group join message from a host, it notes which switch interface it heard the message on, and adds that interface to the group. Similarly, when a Layer 2 switch hears a group leave message or a response timer expires, the switch will remove that host’s switch interface from the group.
•IGMP Querier: IGMP Querier: if the IGMP Querier is enabled, then the router will periodically query all multicast group members on the specified VLAN.
