COMMAND USAGE
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.
EXAMPLE
The following shows how to enable MLD immediate leave.
