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.
