Enabling fast-leave processing

This feature enables the device to immediately remove a port from the forwarding entry for a
multicast group when the port receives a leave massage.
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 in a VLAN. If
fast-leave processing is enabled, the remaining receivers cannot receive multicast data for a
group after a receiver leaves that group.
• You can enable fast-leave processing globally for all ports in IGMP-snooping view or for a port
in interface view. For a port, the port-specific configuration takes priority over the global
configuration.

Disabling a port from becoming a dynamic router port

A receiver host might send IGMP general queries or PIM hello messages for testing purposes. On
the Layer 2 device, the port that receives either of the messages becomes a dynamic router port.
