Enabling Fast-Leave Processing - HPE FlexNetwork 5510 HI Series Configuration Manual

• It sends an unsolicited MLD report when you complete the configuration.
• It responds to MLD general queries with MLD reports.
• It sends an MLD done message when you remove the configuration.
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 ways as a dynamic member port.
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

simulated member host.

Enabling fast-leave processing

This feature enables the device 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-leave processing, follow these restrictions and guidelines:
• Do not enable fast-leave processing on a port that has multiple receiver hosts attached in a
VLAN. If fast-leave processing is enabled, the remaining receivers cannot receive IPv6
multicast data for a group after a receiver leaves that 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.
