Abstract

The invention discloses an IBGP transmission route updating method based on an OSPF protocol. The method comprises the steps of establishing the IBGP peer connection in an autonomous system; enablingeach IBGP router to obtain the Router IDs of all the IBGP routers in the autonomous system; when a route of an IBGP speaker is updated, based on the OSPF link state database of the router, calculatinga minimum spanning tree topological structure of the router; calculating a ring-free topological structure from the router as a root to other IBGP nodes; and connecting the TCP connection for the router and the other IBGP nodes, sending a special Update message, and enabling the other IBGP nodes to receive the message and update the routing information, thereby updating the transmission route ofthe IBGP router. According to the invention, the problem of IBGP transmission route updating full connection is solved, and the problems of complex network planning and router configuration and largenetwork resource consumption in the prior art, are solved.

Description

technical field [0001] The invention relates to the technical field of computer network routing, in particular to an OSPF protocol-based IBGP routing update method. Background technique [0002] The BGP protocol is the most commonly used inter-domain routing protocol. In order to prevent loops, BGP speakers are prohibited from publishing routing information obtained from IBGP to their IBGP peers. In order to transmit routing update information, IBGP within the same autonomous system A full connection relationship should be established between peers. When the number of IBGP peers is large, this method will have a great impact on network resource consumption and router performance. [0003] To solve the IBGP full-mesh problem, there are two existing solutions: BGP route reflection and BGP confederation. [0004] BGP route reflection sets up a route reflection group (Cluster) in the autonomous system, and configures a route reflector in the group. The IBGP peers of the route r...
