IGMP and IGMP Snooping
IP multicast is the transmission of data packets to multiple hosts through a common IP address. Networks use Internet Group Management Protocol (IGMP) to control the flow of layer 3 multicast traffic. Hosts request and maintain multicast group membership through IGMP messages. IGMP snooping is a layer 2 optimization for the layer 3 IGMP protocol that extracts lists of hosts receiving multicast group traffic by monitoring IGMP network packets.
