Abstract
An Internet Group Multicast Protocol (IGMP) proxy provides network redundancy to prevent a severed or damaged line, or a malfunctioning router interface from denying services to the IGMP proxy by outputting the multicast group addresses that are received by the IGMP proxy to a first multicast interface that is electrically connected to a first router interface of a router, and to a second multicast interface that is electrically connected to a second router interface of the router.
