The MLD Snooping Querier is an extension of the MLD snooping feature.
MLD Snooping Querier allows the switch to simulate an MLD router in a
Layer 2-only network, thus removing the need to have an MLD router to
collect the multicast group membership information. The querier function
simulates a small subset of the MLD router functionality.
In a network with IP multicast routing, the IP multicast router acts as the
MLD querier. However, if it is required that the IP-multicast traffic in a
VLAN be switched, the switch can be configured as an MLD querier. When
MLD Snooping Querier is enabled, the querier sends out periodic MLD
general queries that trigger the multicast listeners/member to send their joins
so as to receive the multicast data traffic. MLD snooping listens to these
reports to establish the appropriate forwarding table entries.
