Enabling fast-leave processing
About fast-leave processing
This feature enables the Layer 2 device to immediately remove a port from the forwarding entry for an IPv6 multicast group when the port receives a done message. The device no longer sends or forwards MLD multicast-address-specific queries for the group to the port.
Restrictions and guidelines
Do not enable fast-leave processing on a port that has multiple receiver hosts attached in a VLAN. If you do so, the remaining receivers cannot receive IPv6 multicast data for a group after a receiver leaves the group.
