Abstract

The present invention provides a BGP routing autonomous domain path AS-PATH configuration method and device, wherein the method includes: obtaining one or more AS numbers included in the AS-PATH corresponding to the BGP route; wherein one or more AS ID corresponds to one or more BGP autonomous systems that the BGP route passes through; use one or more specified AS numbers to replace the one or more AS numbers, and change the priority of the BGP route corresponding to AS‑PATH. The invention solves the problem in the related art that the route selection can only be realized by changing the route priority by increasing the length of the AS number, and further realizes the purpose of changing the route priority in various ways to select the route.

Description

technical field [0001] The present invention relates to the communication field, in particular to a BGP routing autonomous domain path AS-PATH configuration method and device. Background technique [0002] Border Gateway Protocol (BGP) routing autonomous domain path (Autonomous System Path, referred to as AS-PATH) is a recognized mandatory attribute of BGP, this attribute records the order of BGP autonomous systems path. When a BGP speaker initiates a route, it will add its own AS number to AS_PATH, that is, every time this route passes through an autonomous system, it will add its own AS number to AS_PATH. AS_PATH can describe all passing autonomous systems. The more AS numbers superimposed, the more passing autonomous systems, and the fewer AS numbers, indicating fewer passing autonomous systems. [0003] AS-PATH can effectively prevent BGP loops. If the AS-PATH of a route received by a BGP speaker from other external peers includes its own AS number, the router conside...
