IGMP Snooping
Internet Group Management Protocol (IGMP) is used by IP hosts to register their
dynamic multicast group membership. IGMP has 3 versions, IGMP v1, v2 and v3.
Please refer to RFC 1112, 2236 and 3376. IGMP Snooping improves the
performance of networks that carry multicast traffic. It provides the ability to
prune multicast traffic so that it travels only to those end destinations that require
that traffic and reduces the amount of traffic on the Ethernet LAN.
