Abstract
A method of transferring foreign protocol information across a hierarchical backbone network is disclosed. The hierarchical backbone network operates according to a first protocol and includes multiple areas, some of which have a destination that operates according to a second protocol. Additionally, each area has at least one router located therein. The locations of the destinations in each area are identified to the router in that area. Information that identifies the locations of the destinations in each area is transferred to a router in each of the other areas regardless of whether the destinations are located in the same area as the router. Finally, information formatted according to the second protocol is transferred among any of the destinations.
