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 a multicast group when the port receives a leave massage. The Layer 2 device no longer sends or forwards IGMP group-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 in a VLAN. If you do so, the remaining receivers cannot receive multicast data for a group after a receiver leaves the group.
