A system constructs an OSPF-compatible virtual model of a multi-hop, multi-access packet radio network that includes a plurality of routers (120) and which includes its own private, internal routing system (150), in order to facilitate the incorporation of that packet radio network into an overall OSPF routing environment. The system determines a network graph identifying actual connectivity among the plurality of routers (120). The system constructs a virtual model (300) of the, wherein connectivity of the virtual model may be different than the actual connectivity of the network graph. The system represents the multi-hop, multi-access radio network in the virtual model as a set of multi-access links (305, 310), point-to-point links, AS-external routes, and area summary routes. The system employs the virtual model for routing purposes and advertises the virtual model to other OSPF routers for the same purpose.

In one embodiment, a method includes receiving authenticated site data that includes site ID data and address data. The site ID data indicates a unique site ID for each site among multiple sites for a first network that uses an internal routing protocol. Multiple edge sites of those sites are separate from each other and connected to a second network that is under separate administrative control of at least one different party. The address data indicates network addresses associated with each site of the plurality of sites. An external routing protocol message is discounted based on the authenticated site data.

The invention discloses a multi-publish-source external routing slave next-hop selection method and equipment. The method comprises the following steps that: after receiving the same external route published by different autonomous system boundary routers (ASBRs), a router calculates master next-hop from the router to the external router and determines a candidate slave next-hop set from the router to the external router, wherein the candidate slave next-hop set consists of the master next-hop and the slave next-hop from the router to the ASBRs which publish the external router or/and the master next-hop and the slave next-hop from the router to a forwarding address (FA) carried in the external route; and the router selects the slave next-hop for the master next-hop from the router to the external router from the candidate slave next-hop set. By adopting the method, aiming at the external route published by multiple sources, the resource expense for calculating the slave next-hop is reduced, and the route constriction speed is increased.

This invention discloses a method for realizing outer route computation of a router which declares an array in the router and sets array items of forwarding-address storing the fifth or the seventh LSA, next hop and route distance route information. If the router needs to compute outer route according to a certain LSA, it looks for the related array items in the array according to the forwarding-address in the said LSA and to get related information from said array directly and compute said outer route if so, otherwise it looks for the related next hop and the route distance information set in the array item and to compute the outer route. It can get the related information only by looking for array with little information to increase efficiency of computing outer routes.
