AI Technical Summary

Problems solved by technology

[0004] If a router fails or is attacked by hackers, a large number of purge LSP packets may be generated and spread to the entire network, resulting in route flapping
In the case of route flapping, the router that generated the purgeLSP message cannot be located, so the source of the fault cannot be quickly located

Embodiment Construction

[0149] In this embodiment of the present application, the router may be a wireless router, or may be a wired router. The router can support interior gateway protocols such as OSPF protocol and ISIS protocol, and no examples are given here.

[0150] In this embodiment of the present application, the routing information update message may be a message related to network topology update and needs to be flooded throughout the network. For example, the routing information update message can be any type of LSA message, any type of LSP message, etc., for example, router (router) LSA message, purge LSP message, purge LSA message Wen and so on.

[0151] Based on the above description, such as figure 1 As shown, it is a schematic flowchart of a message transmission method provided in this embodiment of the present application.

[0152] see figure 1 , the method includes:

[0153] S101: The first router generates a first routing information update packet.

[0154] S102: The first r...

Abstract

The present application discloses a message transmission method and device, which are helpful to trace the source to the source router that generates the routing information update message, and help to improve network maintenance efficiency and shorten fault duration. The method includes: the first router generates a first routing information update message; the first router generates a first source tracing message, and the first source tracing message is used to instruct the first router to generate the first route The source router of the information update message; the first router determines that its adjacent second router has source traceability, and sends the first source trace message to the second router.

Description

technical field [0001] The present application relates to the communication field, and in particular to a message transmission method and device. Background technique [0002] With the development of network technology, customers put forward higher and higher requirements on the reliability and stability of IGP (Interior Gateway Protocol, Interior Gateway Protocol). The IGP protocol includes an OSPF (Open Shortest-Path First, open shortest path first protocol) protocol and an ISIS (Intermediate-System to Intermediate-System, intermediate system to intermediate system) protocol. Among them, the OSPF protocol publishes neighbor information to each node in the whole network in the form of LSA (Link State Advertise, Link State Advertisement), so that each node can perform route calculation. The ISIS protocol publishes neighbor information to each node in the entire network in the form of an LSP (Link State Packet, Link State Packet), so that each node can perform route calculat...
