IGMP Snooping
IGMP Snooping is defined as the process of listening to Internet Group Management Protocol
(IGMP) network traffic. IGMP Snooping allows a network switch to listen in on the IGMP con-
versation between hosts and routers and maintain a map of which links need which IP multi-
cast streams. Multicasts can be filtered from the links which do not need them in turn
controlling which ports receive specific multicast traffic.
