Abstract

The invention provides a border gateway protocol (BGP) route source processing method and device. The BGP route source processing method comprises the steps of acquiring a routing policy used when routing information of an interior gateway protocol (IGP) is injected into a BGP; acquiring preview information generated according to the routing policy; and injecting the routing information of the IGP into the BGP according to the routing policy under the condition that the generated preview information is consistent with predetermined preview information. The BGP route source processing method solves a problem that the IGP cannot be accurately injected into the BGP because of misapplication of the routing policy so as to result in routing oscillation and that IGP injection configuration or routing policy configuration information is required to be repeatedly deleted and reconfigured in related technologies, and solves a problem that routing table best choosing and whole routing table information cannot be previewed after the IGP routing is injected into the BGP, thereby realizing the technical effects of reducing routing flapping from the source, reducing the processing overhead of the a router and improving the network stability.

Description

technical field [0001] The invention relates to the communication field, in particular to a border gateway protocol BGP routing source processing method and device. Background technique [0002] Border Gateway Protocol (BGP for short) is often used to build a policy-based network architecture. BGP can set policies through the attributes provided by itself, and can also use public routing policies to filter and match routes, match and set route attributes. . When an Interior Gateway Protocol (Interior Gateway Protocol, IGP for short) route is injected into the BGP to generate a BGP route source, the BGP route is made to depend on the IGP route. To reduce the amount of information in the BGP routing table and reduce its dependence on IGP routes, routing policies can be used to control the number of injected routing entries and routing attributes. If routing policies are used when IGP routes are injected into BGP, route generation, advertisement, and route attributes may chan...
