Problems solved by technology

Furthermore, once there are network devices with the same System ID on the network, it will cause LSP (Link State Protocol Data Unit, Link State Protocol Data Unit, referred to as LSP) message disorder, increase network traffic, and cause network congestion and routing problems. calculation mistake

Embodiment Construction

[0029] Aiming at the problems existing in the prior art, an embodiment of the present invention provides a System ID management method, which is applied to a network including at least a plurality of network devices, such as an IS-IS network including a plurality of network devices, such as figure 1 As shown, the method may include the following steps:

[0030] In step 101, a network device receives an LSP message, and the LSP message carries a System ID.

[0031] In the embodiment of the present invention, each network device generates an LSP message carrying the System ID of the network device, and sends the LSP message to other network devices. Based on this, each network device can receive the LSP message, and the LSP message carries the System ID of the network device generating the LSP message.

[0032] In the embodiment of the present invention, a new TLV type is added on the basis of the existing TLV (Type-Length-Value) of the IS-IS protocol, and the TLV type is calle...

Abstract

The invention discloses a system ID managing method and device. The method comprises the steps that a network device receives LSP messages carrying System ID; if the System ID carried by the LSP messages is the same as the System ID of the network device, the LSP messages are not LSP messages generated by the network device, the network device generates System ID again, and the System ID of the network device is replaced by the newly-generated System ID. In an embodiment of the invention, network devices with the same System ID in a network can be avoided, and the management maintaining complexity is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and equipment for managing System ID. Background technique [0002] The IS-IS (Intermediate System-to-Intermediate System) protocol is a dynamic routing protocol that is widely used in IP networks. IS-IS protocol has the characteristics of wide application range, fast convergence speed, no loop, and supports routing classification. Therefore, IS-IS protocol is currently one of the most widely used IGP (interior Gateway Protocols, Interior Gateway Protocols) protocols. [0003] The IS-IS protocol uses the System ID (system identifier, 6 bytes in length) to uniquely identify a single network device. In existing implementations, the configuration and change of the System ID are controlled manually, that is, the System ID is manually configured for each network device. In an actual network, especially in a large-scale network environment, due to the large num...
