multicast group exists but does not contains the port received the report message,
the switch adds the port into the multicast group and starts the port aging timer.
And then the switch checks if the corresponding IP multicast group exists. If it does
not exist, the switch creates a new IP multicast group and adds the port received
the report message to it. If it exists, the switch adds the port to it. If the MAC
multicast group corresponding to the message exists and contains the port
received the message, the switch will only reset the aging timer of the port.
IGMP leave message: Transmitted from the multicast group member to the
multicast router to notify that a router host left the multicast group. When received
a leave message of an IP multicast group, the Ethernet switch transmits the
specific query message concerning that group to the port received the mess
in order to check if the host still has some other member of this group and
meanwhile starts a maximum response timer. If the switch has not receive any
report message from the multicast group, the port will be removed from the
corresponding MAC multicast group. If the MAC multicast group does not have
any member, the switch will notify the multicast router to remove it from the
multicast tree.
