snooping
IGMP Snooping is a method that actually “snoops” or inspects
IGMP traffic on a switch. When enabled, the switch will watch for
IGMP messages passed between a host and a router, and will
add the necessary ports to its multicast table, ensuring that only
the ports that require a given multicast stream actually receive it.
