Manage Multicast Traffic With IGMP
Snooping
Internet Group Management Protocol (IGMP) snooping allows a switch to forward multicast
traffic intelligently on the switch. Multicast IP traffic is traffic that is destined to a host group.
Host groups are identified by Class D IP addresses, which range from 224.0.0.0 to
239.255.255.255. Based on the IGMP query and report messages, the switch forwards traffic
only to the ports that request the multicast traffic. This feature prevents the switch from
broadcasting the traffic to all ports and possibly affecting network performance.
The switch maintains a map that shows which links need which IP multicast streams. The
switch forwards multicast traf
fic only to the links that requested them and cuts multicast traffic
from links that do not contain a multicast listener. Essentially, IGMP snooping helps optimize
multicast performance at Layer 2 and is especially useful for bandwidth-intensive IP multicast
applications such as IPTV.
