Embodiment Construction

[0023] The route publishing method provided by this application is not limited to publishing BGP routes with exactly the same routing attributes in the same UPDATE message, but can also publish BGP routes with little difference in attributes in the same UPDATE message , which can reduce the number of UPDATE packets sent, advertise a large number of BGP routes faster, improve the efficiency of BGP route advertisement, and improve the convergence performance of BGP.

[0024] In order to make the purpose, technical solutions and advantages of the present application clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0025] see figure 1 , figure 1 The flow chart of the route publishing method provided by this application. This method is applied to network devices running BGP.

[0026] Such as figure 1 As shown, the process may include the following steps:

[0027] Step 101, when publishing...

Abstract

The application provides a routing publishing method and device. In the application, not only BGP (Border Gateway Protocol) routes with identical routing attributes can be carried in the same UPDATE message to be published, but also BGP routes with similar attributes can be carried in the same UPDATE message to be published. Thus, the number of UPDATE packets can be reduced; a large number of BGProutes can be published faster; the BGP routing publishing efficiency is increased; and the BGP convergence performance is improved.

Description

technical field [0001] The present application relates to network communication technology, and in particular to a method and device for publishing routes. Background technique [0002] When the network device monitors that the BGP (Border Gateway Protocol, Border Gateway Protocol) neighbor between the device and the peer device is successfully established, it publishes the local optimal BGP route through the BGP neighbor, and then only publishes the optimal BGP route whose routing attributes have changed. routing. [0003] Among them, when the network device publishes the BGP route, it will carry the BGP route with the same routing attribute in the same UPDATE (update) message and publish it, which can reduce the number of UPDATE message packets and send a large number of BGP routes faster. Out, improve the convergence performance of BGP. [0004] The routing attributes of BGP routing are suitable for routing control and propagation, including but not limited to the follo...
