4.6 IGMP Snooping
IGMP Snooping is the process of listening to IGMP network traffic. IGMP Snooping, as implied by
the name, is a feature that allows a layer 2 switch to "listen in" on the IGMP conversation between
hosts and routers by processing the layer3 IGMP packets sent in a multicast network.
When IGMP Snooping is enabled in a switch it analyzes all IGMP packets between hosts connected
to the switch and multicast routers in the network. When a switch hears an IGMP report from a
host for a given multicast group, the switch adds the host's port number to the multicast list for
that group. And, when the switch hears an IGMP Leave, it removes the host's port from the table
entry.
Prevents flooding of IP multicast traffic, and limits bandwidth intensive video traffic to only the
subscribers.
