fast-leave (MLD-snooping view)
Use fast-leave to enable fast-leave processing globally. With this function enabled, when the device
receives an MLD done message on a port, it directly removes that port from the forwarding table entry for
the specific IPv6 multicast group.
Use undo fast-leave to disable fast-leave processing globally.
Syntax
fast-leave [ vlan vlan-list ]
undo fast-leave [ vlan vlan-list ]
Default
Fast-leave processing is disabled.

Parameters
vlan vlan-list: Specifies one or multiple VLANs. You can provide up to 10 VLAN lists. For each list, you
can specify an individual VLAN in the form of vlan-id, or a VLAN range in the form of start-vlan-id to
end-vlan-id, where the end VLAN ID must be greater than the start VLAN ID. The value range of a VLAN
ID is 1 to 4094. If you do not specify any VLAN, the command applies to all VLANs. If you specify one
or multiple VLANs, the command applies to only the specified VLANs.
