Configuring IGMP
Internet Group Management Protocol (IGMP) is a communication protocol used by
hosts and adjacent routers on IP networks to establish multicast group
memberships. IGMP can be used for online streaming video and gaming, and can
allow more efficient use of resources when supporting these types of
applications.
IGMP Proxy enables hosts that are not directly connected to a downstream router
to join a multicast group sourced from an upstream network. IGMP Snooping
constrains IPv4 multicast traffic at Layer 2 by configuring Layer 2 LAN ports
dynamically to forward IPv4 multicast traffic only to those ports that want to
receive it.
