Title: Method and system for exchanging routing information

Abstract: A host computer is operated as a gateway interfacing a plurality of network interfaces in a communication system including local area networks and wide area networks. A redistribution parameter is maintained in a configuration file for each of a plurality of network interfaces, with the redistribution parameter defaulted to *full for local area network interfaces and to *limited for wide area network interfaces. Responsive to receiving a routing update (a route) from a wide area network interface, the route is advertised to interfaces having a redistribution parameter of *full and not to those interfaces having a redistribution parameter of *limited.
