1.1.2 IGMP Snooping Fundamentals
I. IGMP Snooping terminologies
Before going on, we first describe the following terms involved in IGMP Snooping:
z Router port: the switch port directly connected to the multicast router.
z Multicast member port: a switch port connected to a multicast group member (a
host in a multicast group).
z MAC multicast group: a multicast group identified by a MAC multicast address and
maintained by the switch.
The following three timers are closely associated with IGMP snooping.
