Abstract
Systems and methods are provided for routing packets on a network based on interface information of a routing gateway or a neighboring gateway. One embodiment includes updating a routing table using interface information shared by a neighboring router. Another embodiment includes making routing decisions based on interface information from a neighboring router. A further embodiment includes making routing decisions based on priorities determined from interface information. Another embodiment includes the steps of updating a routing table on a first gateway, which includes the steps of receiving data disclosing interface information on a neighboring second gateway, and updating a routing table based on the interface information. The interface information for the neighboring second gateway includes identification of communication interfaces on the second gateway, an interface type for each of the interfaces, and a physical type interface on which each virtual type interface is overlaid.
