ipv6 mld snooping vlan immediate-leave
This command enables or disables MLD Snooping immediate-leave mode on
a selected VLAN. Enabling immediate-leave allows the switch to immediately
remove the layer 2 LAN interface from its forwarding table entry upon
receiving an MLD done message for that multicast group without first
sending out MAC-based general queries to the interface.
