Processing Leaves
When host C1 decides to leave a multicast group it will issue a leave request to the switch. The
switch will poll the port to determine if C1 is the last member of the group on that port. If C1 is
the last (or only) member, the group will immediately be pruned from the port.
Should host C1 leave the multicast group without issuing a leave group message and then fail
to respond to a general membership query, the switch will stop forwarding traffic after two
queries.
When the last port in a multicast group leaves the group (or is aged-out) the switch will issue an
IGMP leave report to the router.
