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.
