Enabling fast-leave processing
This feature enables the IGMP querier to send a leave notification directly to the upstream without sending IGMP group-specific queries or IGMP group-and-source-specific queries after receiving a leave message. This reduces leave latency and preserves the network bandwidth.
The fast-leave processing configuration is effective only when the device runs IGMPv2 or IGMPv3.
