Fast Leave
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 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.
