Use igmp fast-leave to enable fast-leave processing on an interface.

Use undo igmp fast-leave to disable fast-leave processing on an interface.

Syntax

igmp fast-leave [ group-policy acl-number ]

undo igmp fast-leave

Default

Fast-leave processing is disabled. The IGMP querier sends IGMP group-specific queries or IGMP

group-and-source-specific queries after receiving an IGMP leave message from a host, instead of sending

a leave notification directly to the upstream.
