fast-leave (IGMP view)
Syntax
fast-leave [ group-policy acl-number ]
undo fast-leave
View
Public network IGMP view, VPN instance IGMP view
Default level
2: System level
Parameters
acl-number: Basic ACL number, in the range of 2000 to 2999. If you do not include this option in your
command, this command takes effect for all multicast groups.
Description
Use fast-leave to enable fast-leave processing globally.
Use undo fast-leave to disable fast-leave processing globally.
By default, fast-leave processing is disabled, and 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.
When executed in IGMP view, this command takes effect only on Layer 3 interfaces except VLAN
interfaces.
Related commands: igmp fast-leave and last-member-query-interval.
