Configuring IGMP Snooping
Internet Group Management Protocol (IGMP) is used by both IP hosts and multicast routers. IP hosts use
IGMP to report their multicast group memberships to any immediate-neighboring multicast router.
Routers use the query message on its interface to solicit multicast group membership information from
clients.
IGMP snooping is the process of listening to IGMP traffic. IGMP snooping allows the controller to listen
in on an IGMP conversation between hosts and routers by processing layer 3 packets IGMP packets sent
in a multicast network.
The goal of IGMP is to learn multicast router ports and snoop IGMP join requests/reports to build a
portal list to forward multicast packet to interested hosts only on that Portal, thus optimizing the
flooding of multicast packets.
