IGMP settings
The Internet Group Management Protocol (IGMP) is a communications protocol used by hosts
and adjacent routers on IP networks to establish multicast group memberships. IGMP can be
used for one-to-many networking applications, such as online streaming video and gaming,
and allows more efficient use of resources when supporting these types of applications.
This page includes the following settings:
Enable IGMP Proxy
IGMP proxy actively filters IGMP packets in order to reduce the load on the multicast router.
Join and leave messages heading upstream to the router are filtered so that only the minimal
quantity of information is sent.
Enable IGMP Snooping
IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP)
network traffic. The feature allows a network switch to monitor the IGMP conversation between
hosts and routers. By monitoring these conversations, the switch maintains a map of which links
need which IP multicast streams. Multicast traffic can be filtered from the links that do not need
them, and thus control the ports that receive specific multicast traffic.
