The Internet Group Management Protocol (IGMP) (RFC 4604) implementation is used to learn and proxy the group membership information of the hosts connected to a router. Multicast routing protocols, like PIM, use this information to forward multicast packets that are received by the router. An IGMP proxy learns group membership and forwards multicast traffic based on this information. The proxy does not need to run any multicast routing protocols. IGMP proxy substitutes the information to upstream router interface, based on the requirements of IGMP hosts. This release of the firmware provides support for IGMP proxy.
