Multicast snooping Fast Leave processing allows the switch to remove an interface from
the forwarding-table entry without first sending out group specific queries to the
interface. The VLAN (Virtual LAN) interface is pruned from the multicast tree
for the multicast group specified in the original leave message. Fast-leave processing
ensures optimal bandwidth management for all hosts on a switched network, even when multiple
multicast groups are in use simultaneously. This processing applies to IGMP (Internet Group Management Protocol) and MLD (Multicast Listener Discovery).
