Embodiment 1

[0035] The routing processing method applied to BGP in the first embodiment of this application can be executed by any routing and forwarding device (that is, a BGP speaker), and the routing and forwarding device can be a router, etc., which is not limited in this application.

[0036] It should be noted that the first routing and forwarding device in the following can be any routing and forwarding device running BGP, and does not specifically refer to a certain routing and forwarding device, and the second routing and forwarding device can be any of the first routing and forwarding devices. A BGP peer.

[0037] Such as figure 2 As shown, the routing processing method includes the following steps:

[0038] Step S201: The first routing and forwarding device receives configuration information for the routing-out policy, where the configuration information includes location setting rules for setting location information of the device in the routing;

[0039] Obviously, the configuration...

Embodiment 2

[0057] On the basis of the method in the first embodiment, it is also possible to add a location matching rule for filtering routes carrying location information in the route in policy. Upon receiving the BGP peer: the third route forwarding device sent After routing information, the third routing information can be processed according to the routing entry policy, specifically, the third routing information can be filtered according to the location matching rule. Therefore, it is possible to perform filtering processing on the received routes carrying location information.

[0058] In this way, the routing processing method in the second embodiment of the present application further includes the following steps:

[0059] Step S301: The first routing and forwarding device receives configuration information for the route in policy, where the configuration information includes a location matching rule for filtering routes carrying location information, and the location matching rule i...

Embodiment 3

[0077] Below Figure 5 The shown network is taken as an example to illustrate the routing processing of the embodiment of the present application in detail. in Figure 5 In, router A is the router of operator A Beijing, the location information is Provider A Beijing (operator A Beijing); router B is the router of operator B Hangzhou, and the location information is Provider B Hangzhou; router C It is the router of operator C Nanjing. The location information is Provider C Nanjing (operator Nanjing). BGP runs between router A and router B, and between router A and router C. Take router A as the first routing and forwarding device in the first and second embodiments, and router B and router C as the second routing and forwarding devices. In the third embodiment, the specific process for router A to process routing information includes the following steps:

[0078] Step S401: Router A enables location information carrying capability;

[0079] Step S402: Router A and BGP peers: Rou...

Abstract

The invention discloses a routing processing method and routing forward equipment, which are applied to a BGP (border gateway protocol). The method comprises the following steps that the first routing forward equipment receives configuration information aiming at routing-out strategies, wherein the configuration information comprises position settling rules used for position information of equipment in routing; when the routing information is issued, the first routing forward equipment processes the first routing information to be issued according to the routing-out strategies, and the second routing information is obtained, wherein the position information of the first routing forward equipment is carried in each routing in the second routing information; and the first routing forward equipment issues the second routing information to the second routing forward equipment, wherein the second routing forward equipment is a BGP peer body of the first routing forward equipment. The position information is carried in the BGP routing, so the BGP routing source can be conveniently and distinctly obtained.

Description

Technical field [0001] This application relates to the field of IP (Internet Protocol, Internet Protocol) routing technology, in particular to a routing processing method and routing and forwarding equipment. Background technique [0002] BGP (Border Gateway Protocol) is a dynamic routing protocol that can be used between different ASs (Autonomous Systems) and within the same AS. When BGP runs within the same AS, it is called IBGP (Internal BGP); when BGP runs between different ASs, it is called EBGP (External BGP). Among them, AS is a group of routers that have the same routing strategy and belong to the same technical management department. [0003] In the BGP protocol, the router running the BGP protocol is called the BGP Speaker. BGP speakers receive or generate routing information, and advertise the routing information to other BGP speakers. There is a TCP (Transmission Control Protocol, Transmission Control Protocol) connection between each other and the BGP speakers that ...
