ipv6 mld snooping immediate-leave
The ipv6 mld snooping immediate-leave command enables or disables MLD Snooping
snooping immediate-leave admin mode on a selected interface or VLAN. Enabling fast-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. You should enable fast-leave admin mode only on
VLANs where only one host is connected to each layer 2 LAN port. This prevents the
inadvertent dropping of the other hosts that were connected to the same layer 2 LAN port but
were still interested in receiving multicast traffic directed to that group. Also, fast-leave
processing is supported only with MLD version 1 hosts.
