Host

router
and
multicast
switch
Notify the
multicast
router
and
multicast
switch
that the
host is
leaving
its
multicast
group.
Multicast router and multicast
switch send IGMP specific
group query packet(s) to the
multicast group whose
member host sends leave
packets to check if the
multicast group has any
members and enable the
corresponding query timer.
If no response is
received from
the multicast
group before the
timer times out,
notify the router
to remove this
multicast group
node from the
multicast tree
Caution:
An IGMP-Snooping-enabled S5600 series Ethernet switch judges whether the
multicast group exists when it receives an IGMP leave packet sent by a host in a
multicast group. If this multicast group does not exist, the switch will drop the IGMP
leave packet instead of forwarding it.
