Abstract
An apparatus and method for processing multicast traffic in a given multicast domain aggregates one or more multicast interfaces into an aggregation interface, each multicast interface linked to a multicast domain other than the given multicast domain via a domain interface, the aggregation interface linked to the given multicast domain via an inbound interface. The apparatus and method then receives at the aggregation interface one or more multicast domain group membership messages from one or more of the other multicast domains, forwards multicast traffic for a particular multicast group from the given multicast domain towards the one or more other multicast domains via the inbound interface, and determines whether one or more of the other multicast domains is interested in the particular multicast group. Last, the apparatus and method, for each other multicast domain determined to be interested in the particular multicast group, establishes the domain interface as the outbound interface for the forwarded multicast traffic.
