IGMP Snooping
IGMP Snooping (Internet Group Management Protocol Snooping) is the multicast constraint
mechanism running on the device of layer 2, for managing and controlling the multicast. Through
analyzing the received IGMP packet, the device of layer 2, which runs IGMP Snooping, creates the
mapping between the port and the MAC multicast address, and forwards the multicast data
according to the mapping.
