Configuring Mld Fast-Leave Processing - HP A8800 Configuration Manual

Step
7. Configure the maximum
response delay for MLD
general query messages.
8. Configure the MLD last
listener query interval.
9. Configure the MLD other
querier present interval.

Configuring MLD fast-leave processing

In some applications, such as ADSL dial-up networking, only one multicast receiver host is attached to a
port of the MLD querier. To allow fast response to the MLD done messages of the host when it switches
frequently from one IPv6 multicast group to another, you can enable MLD fast-leave processing on the
MLD querier.
With fast-leave processing enabled, after receiving an MLD done message from a host, the MLD querier
sends a
multicast-address-specific queries. In this way, the leave latency is reduced and the network bandwidth
is saved.

By default, the other querier
present interval is determined by
the formula "Other querier present
interval (in seconds) = [ MLD query
interval ] × [ MLD querier's
robustness variable ] + [ maximum
response delay for MLD general
query ] /2."
