Enabling fast-leave processing

This feature enables an MLD querier to send leave notifications to the upstream without sending
multicast-address-specific or multicast-address-and-source-specific queries after receiving a done
message. Use this feature to reduce leave latency and to preserve the network bandwidth.
To enable fast-leave processing:

Remarks
By default, the maximum
response time for MLD general
queries is 10 seconds.
By default, the MLD other querier
present timer is calculated by
using the following formula:
[ MLD general query interval ] ×
[ MLD robustness variable ] +
[ maximum response time for MLD
general queries ] / 2.
Remarks
N/A
N/A
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 calculated by
using the following formula:
[ MLD general query interval ] ×
[ MLD robustness variable ] +
[ maximum response time for MLD
general queries ] / 2.
