multicast fast-leave-v2
Fast leave for IGMP V2 is not configured.
VLAN configuration mode
The
no form of this command restores the default; fast leave for IGMP V2 is not configured.
When a device receives an IGMP V2 leave message, it sends out multiple group-specific
queries. If no other client replies within the waiting period, the device stops forwarding
traffic. When the
multicast fast-leave-v2 command is configured, and when the device receives a leave message, it immediately
stops forwarding to that port. The device does not send group specific-queries. When
the
multicast fast-leave-v2 command is configured on a VLAN, you must not have multiple clients on any port that
is part of the VLAN.
In a scenario where two devices connect, the querier device should not be configured for fast-leave-v2 because the port might have multiple clients through the non-querier.
You can configure the
ip multicast leave-wait-time command to set the number of queries and the waiting period.
