Enabling Fast-Leave Processing - HP FlexNetwork 7500 Series Configuration Manual

The version of MLD running on the simulated member host is the same as the version of MLD
snooping running on the port. The port ages out in the same way as a dynamic member port.
Configuration procedure
To configure a port as a simulated member host:
Step
Enter system view.
1.
Enter Layer 2 Ethernet
2.
interface view or Layer 2
aggregate interface view.
Configure the port as a
3.
simulated member host.

Enabling fast-leave processing

This feature enables the switch to immediately remove a port from the forwarding entry for an IPv6
multicast group when the port receives a done message.
Configuration restrictions and guidelines
When you enable fast-leaving processing, follow these restrictions and guidelines:
•
Do not enable fast-leave processing on a port that have multiple receiver hosts attached in a
VLAN. If fast-leave processing is enabled, after a receiver host leaves an IPv6 multicast group,
the other receivers cannot receive IPv6 multicast data for the group.
•
You can enable fast-leave processing globally for all ports in MLD-snooping view or for a port in
interface view. For a port, the port-specific configuration takes priority over the global
configuration.
