Abstract
A method of merging networks across a common backbone network in which destinations are grouped into domains based on needs of network users to communicate with one another. Domain information is added to the level one routing control packets transmitted by the grouped destinations to identify the logical address (destination number coupled with domain number) of a specific destination. Additionally, routers in the network are configured with mapping information that relates the destination number of each associated destination with its logical address. Filtering information may be included in the configuration of the level one and level two routers. Filtering information identifies domains that associated destinations may transmit information to or receive information from. With filtering information, system routers can be configured to announce the reachability of specific destinations in selected domains based on overall system considerations.
