Syntax fast-leave [ group-policy acl-number ]
undo fast-leave
View Public instance IGMP view, VPN instance IGMP view
Parameter acl-number: Basic ACL number, in the range of 2000 to 2999.
Description Use the fast-leave command to enable the fast-leave function for multicast
group members globally.
Use the undo fast-leave command to disable the fast-leave function globally.
By default, the fast-leave function is disabled, namely, the IGMP querier sends an
IGMP group-specific query upon receiving an IGMP leave message from a host,
instead of sending a Leave notification directly to the upstream.
Related command: igmp fast-leave, last-member-query-interval.
nThis command takes effect on all Layer 3 interfaces when executed in IGMP view.
