Displaying And Maintaining Igmp; Igmp Configuration Examples; Network Requirements - HP 6125XLG Ip Multicast Configuration Manual

With this feature enabled, after receiving an IGMP leave message, the IGMP querier does not send
IGMP group specific queries or IGMP group and source specific queries. Instead, it directly sends a leave
notification to the upstream. This reduces leave latency and preserves the network bandwidth.
The IGMP fast-leave processing configuration is effective only if the device is running IGMPv2 or
IGMPv3.
To enable IGMP fast-leave processing:
Step
1. Enter system view.
2. Enter interface view.
3. Enable IGMP fast-leave
processing.
