IPv6 MLD Snooping Querier
Commands
IGMP/MLD Snooping Querier is an extension of the IGMP/MLD Snooping
feature. IGMP/MLD Snooping Querier allows the switch to simulate an
IGMP/MLD router in a Layer 2-only network, thus removing the need to have
an IGMP/MLD Router to collect the multicast group membership
information. The querier function simulates a small subset of the
IGMP/MLD router functionality.
In a network with IP multicast routing, the IP multicast router acts as the
IGMP/MLD querier. However, if it is required that the IP-multicast traffic in
a VLAN be switched, the switch can be configured as an IGMP/MLD querier.
When IGMP/MLD Snooping Querier is enabled, the Querier sends out
periodic IGMP/MLD General Queries that trigger the Multicast
listeners/member to send their joins so as to receive the Multicast data traffic.
IGMP/MLD Snooping listens to these reports to establish the appropriate
forwarding table entries.
PowerConnect switches support IGMP V1 and 2 for snooping IGMP queries.
