Communication method and device

Abstract

Disclosed is a communication method which comprises the following step that a first network device obtains a first route, a second route and a third route from a second network device, wherein the third route comprises a network segment route corresponding to a segment identifier SRv6SID of a sixth version segment route of an Internet protocol, the network segment corresponding to the third route is a sub-network segment of the network segment corresponding to the first route, the network segment corresponding to the third route is a sub-network segment of the network segment corresponding to the second route, the network segment corresponding to the first route is a sub-network segment of the network segment corresponding to the second route, and the first network device sets the output interface of the first route as a null0 output interface. Or, the first network device obtains a third route from the second network device, and the third route comprises a network segment route corresponding to the SRv6SID; when the first network equipment determines that the third route is unreachable, an output interface of the third route is set as a null0 output interface; the first network device deletes the third route after waiting for a preset time. By utilizing the method, the packet loss rate of message forwarding can be reduced.

Description

[0001] This application is required to be submitted to the China Patent Office on October 22, 2019, the application number is 201911008408.2, the name of the invention is "a method, device and system for generating routing information" and it was submitted to the China Patent Office on October 30, 2019, The priority of the Chinese patent application with the application number 201911046892.8 and the invention titled "A Communication Method and Device", the entire contents of which are incorporated in this application by reference. technical field [0002] The present application relates to the communication field, and in particular to a communication method and device. Background technique [0003] With the development of communication technology, the scale of the communication network becomes larger and larger, which leads to an increasing amount of data in a routing information base (routing information base, RIB) stored in network devices. In order to reduce the data volu...
