mld fast-leave
Use mld fast-leave to enable MLD fast-leave processing on an interface.
Use undo mld fast-leave to disable MLD fast-leave processing on an interface.
Syntax
mld fast-leave [ group-policy acl6-number ]
undo mld fast-leave
Default
MLD fast-leave processing is disabled. The MLD querier sends multicast-address-specific queries or
multicast-address-and-source-specific queries after receiving an MLD done message from a host, instead
of sending a leave notification directly to the upstream.

Parameters
acl6-number: Specifies an IPv6 basic ACL by its number in the range of 2000 to 2999. The fast-leave
processing function takes effect on only the IPv6 multicast groups that the ACL permits. If no ACL is
specified, the command takes effect on all IPv6 multicast groups.
Examples
# Enable MLD fast-leave processing on GigabitEthernet 2/1/1.

[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] mld fast-leave

multicast groups that the hosts on the interface can join.
Use undo mld group-policy to remove the configured IPv6 multicast group filter.
Syntax
mld group-policy acl6-number [ version-number ]
undo mld group-policy
Default
No IPv6 multicast group filter is configured on an interface, and a host can join any IPv6 multicast group.
