Querier Config
In an IP multicast network that runs IGMP, a Layer 3 multicast device works as an IGMP querier
to send IGMP queries and manage the multicast table. But IGMP is not supported by the
devices in Layer 2 network. IGMP Snooping Querier can act as an IGMP Router in Layer 2
network. It can help to create and maintain multicast forwarding table on the switch with the
Query messages it generates.
