IGMP Snooping

IGMP snooping allows a Secure Router to read (snoop) IGMP packets transferred between IP
multicast routers and IP multicast hosts to learn the IP Multicast group membership. Without
IGMP Snooping, the Secure Router handles IP multicast traffic in the same manner as network
broadcast traffic and forward frames received on one interface to all other interfaces. This
creates excessive traffic on the network and affects network performance. IGMP Snooping
allows routers to monitor network traffic and determine hosts that want to receive multicast
traffic.
