Enabling Mld Fast-Leave Processing; Displaying And Maintaining Mld - HP 6125XLG Ip Multicast Configuration Manual

Enabling MLD fast-leave processing

In some applications, such as ADSL dial-up networking, only one multicast receiver host is attached to an
interface of the MLD querier. The receiver host might switch frequently from one IPv6 multicast group to
another. 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 fast-leave processing on the MLD querier.
With this feature enabled, the MLD querier sends a leave notification to the upstream immediately after
receiving an MLD done message from a host. It does not send MLD multicast address specific queries.
This reduces leave latency and preserves the network bandwidth.
To enable MLD fast-leave processing:
Step
1. Enter system view.
2. Enter interface view.
3. Enable MLD fast-leave
processing.

Displaying and maintaining MLD

CAUTION:
The reset mld group command might cause IPv6 multicast data transmission failures.
Execute display commands in any view and reset commands in user view.
Task

entries of the specified MLD group
or all MLD groups.
