Abstract:
1. A method for processing multicast traffic in a given multicast domain, the method comprising: aggregating 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; receiving at the aggregation interface one or more multicast domain group membership messages from one or more of the other multicast domains; forwarding multicast traffic for a particular multicast group from the given multicast domain towards one or more of the other multicast domains via the inbound interface; determining whether one or more of the other multicast domains is interested in the particular multicast group; and for each other multicast domain determined to be interested in the particular multicast group, establishing the domain interface as an outbound interface for the forwarded multicast traffic.
