User Guidelines
When an MLD Leave Group message is received from a host, the system removes
the host port from the table entry. After it relays the MLD queries from the
Multicast router, it deletes entries periodically if it does not receive any MLD
membership reports from the Multicast clients.
MLD snooping Immediate-Leave processing allows the switch to remove an
interface that sends a leave message from the forwarding table without first
sending out MAC-based general queries to the interface.
You can execute the command before the VLAN is created.
Example
switchxxxxxx(config)# ipv6 mld snooping vlan 1 immediate-leave
