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.
