IPv6 MLD Snooping Commands

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.
