Abstract:
1. A method for distributing routing information between nodes in networks, said method comprising the steps of: a) receiving a routing data packet from a subgroup of nodes in said network, said routing data packet being received at a first router directly connected to said subgroup; b) assigning, by the first router, a routing parameter to said routing data packet, said routing parameter being dependent on said subgroup; c) propagating said routing data packet with said routing parameter to a second router in accordance with a first routing protocol; d) receiving said routing data packet at said second router; e) translating said routing parameter for use in a second routing protocol; and f) propagating said routing data packet, including said translated routing parameter, externally to said network in accordance with said second routing protocol; wherein said routing parameter identifies said subnet to which said first router is directly connected; wherein said first router is directly connected to a plurality of subnets, and wherein said routing parameter identifies a specific one of said subnets but not others of said subnets.
