If MLD immediate-leave is not used, a multicast router (or querier) will
◆
send a group-specific query message when an MLD group leave
message is received. The router/querier stops forwarding traffic for that
group only if no host replies to the query within the specified timeout
period.
◆ If MLD immediate-leave is enabled, the switch assumes that only one
host is connected to the interface. Therefore, immediate leave should
only be enabled on an interface if it is connected to only one MLD-
enabled device, either a service host or a neighbor running MLD
snooping.

The following shows how to enable MLD immediate leave.
Console(config)#interface vlan 1
Console(config-if)#ipv6 mld snooping immediate-leave
Console(config-if)#
This command statically configures an IPv6 multicast router port. Use the
no form to remove the configuration.

Depending on your network connections, MLD snooping may not always be
able to locate the MLD querier. Therefore, if the MLD querier is a known
multicast router/switch connected over the network to an interface (port or
trunk) on the switch, you can manually configure that interface to join all
the current multicast groups.
