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 this application, route release is controlled to ensure that the route can be successfully delivered to the hardware before the release, avoiding the situation that the route has been released but not yet delivered to the hardware, and prevents traffic interruption.

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

[0025] see figure 2 , figure 2 Flow chart of the method provided for this application. This process is applied to a network device running BGP. In actual implementation, the network device may be a router, a switch, a virtual machine, a server, a mobile terminal, or other devices capable of running BGP.

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

[0027] Step 201, when a route is received, record the route in the route link list to be published, and check th...

Abstract

This application provides a method and device for publishing routes. In this application, the network device controls the release speed of the route, so that the route is successfully delivered to the hardware before the release, avoiding the situation that the route has been published but not yet delivered to the hardware, and traffic interruption is prevented.

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] For a network device running Border Gateway Protocol (BGP: Border Gateway Protocol) (BGP device for short), after learning the optimal route advertised by BGP neighbors, it sends the optimal route to the hardware to guide traffic forwarding. On the one hand, it advertises the optimal route 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 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 figu...
