Problems solved by technology

However, in order to maintain high performance, the BGP device does not wait for the hardware to deliver routes successfully before advertising routes. The situation that has not been delivered to the hardware
[0004] by figure 1 The timing diagram of the network device processing routing shown in the example, as shown in figure 1 As shown, the network device has advertised the route 1_3 to the neighbors, but has not delivered it to the hardware. At this time, if the network device receives the traffic of the route 1_3, the traffic will be blocked because the route 1_3 has not been delivered to the hardware, and there will be a short-term traffic interruption

Embodiment Construction

[0023] In the present application, route publishing is controlled to ensure that the route can be successfully delivered to the hardware before it is advertised, so as to avoid the situation where the route has been advertised but not yet delivered to the hardware, and prevent traffic interruption.

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

[0025] see figure 2 , figure 2 The flow chart of the method provided in this application. This process is applied to a network device running BGP. When specifically implemented, the network device may be a device that can run BGP, such as a router, a switch, a virtual machine, a server, and a mobile terminal.

[0026] like figure 2 As shown, the process may include the following steps:

[0027] Step 201: When the route is received, the r...

Abstract

The invention provides a route publishing method and device. According to the method and the device, network equipment controls the publishing speed of a route, so that the route is successfully issued to hardware before being issued, the situation that the route is issued but not issued to the hardware is avoided, and the flow interruption is prevented.

Description

technical field [0001] The present application relates to network communication technologies, and in particular, to a method and apparatus for publishing routes. Background technique [0002] For a network device (BGP device for short) running the Border Gateway Protocol (BGP), after learning the optimal route advertised by BGP neighbors, on the one hand, it sends the optimal route to the hardware to guide traffic forwarding, and on the other hand On the one hand, the optimal route is advertised to BGP neighbors. [0003] Usually, the BGP device will deliver the route to the hardware first, and then advertise the route to the neighbors after the delivery is successful. However, in order to maintain high performance, the BGP device does not wait for the successful route delivery hardware before publishing the route. This will lead to some situations, such as a large amount of routes, that the route has been advertised to the neighbor, but It has not been distributed to the ...
