Usage
Information
Queriers normally send some queries when a leave message is received prior to
deleting a group from the membership database. There may be situations when
you require a fast deletion of a group. When you enable IGMP fast leave
processing, the switch removes an interface from the multicast group as soon as it
detects an IGMP version 2 leave message on the interface.
