Enabling fast-leave processing

This feature enables an MLD querier to send a leave notification directly to the upstream without
sending multicast-address-specific queries or multicast-address-and-source-specific queries after
receiving a done message. This reduces leave latency and preserves the network bandwidth.
To enable fast-leave processing:

Enabling MLD NSR
This feature enables the switch to back up information about MLD interfaces and MLD forwarding
entries to the standby process. After an active/standby switchover, the switch can recover the

By default, the MLD querier's
robustness variable is 2.
By default, the MLD startup query
interval equals one quarter of the
MLD general query interval.
By default, the MLD startup query
count equals the MLD querier's
robustness variable.
By default, the MLD general query
interval is 125 seconds.
By default, the MLD last listener
query interval is 1 second.
By default, the MLD last listener
query count equals the MLD
querier's robustness variable.
By default, the maximum
response time for MLD general
queries is 10 seconds.
By default, the MLD other querier
present timer is [ MLD general
query interval ] × [ MLD
robustness variable ] +
[ maximum response time for
MLD general queries ] / 2.
