Fast Leave
Enable or disable fast-leave processing on the port.
When a port that is enabled with the MLD snooping fast-leave processing feature receives
an MLD done message, the switch immediately deletes that port from the IPv6 forwarding
table entry for the IPv6 multicast group specified in the message. When the switch receives
MLD multicast-address-specific queries for that multicast group, it does not forward them to
that port.
On a port that has only one host attached, you can enable fast-leave processing to save
bandwidth and resources. However, on a port that has multiple hosts attached, do not
enable fast-leave processing if you have enabled dropping unknown IPv6 multicast data
for the VLAN to which the port or the switch belongs. Otherwise, if a host on the port
leaves an IPv6 multicast group, the other hosts attached to the port in the same IPv6
multicast group cannot receive the IPv6 multicast data for the group.
