Querier Config - TP-Link T1700X-16TS User Manual

8.1.5 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.
