Configuring MLD Snooping Querier
Use the following commands to configure MLD snooping querier settings on
the switch and on VLANs.

id last-listener-query-
interval seconds
Specify the leave time-out value for the VLAN. If an MLD
report for a multicast group is not received within the
number of seconds configured with this command after
an MLD leave was received from a specific interface, the
current port is deleted from the VLAN member list of that
multicast group.
ipv6 mld snooping vlan

specified VLAN. Enabling immediate-leave allows the
switch to immediately remove the Layer-2 LAN interface

leave message for that multicast group without first
sending out MAC-based general queries to the interface.
