Problems solved by technology

[0004] like figure 2 As shown, when the link of the upstream device fails, for example, the link between the S3 device and the core router is completely interrupted, the VRRP status of S1 and S2 will not change at this time, S1 is still the MASTER devi

Embodiment Construction

[0030] Various preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] The implementation method of notifying the downstream device when the uplink state is switched in the present invention, its main improvement point is to configure a tracking command, namely the TRACK command, in the uplink device in the prior art, and the TRACK command tracks and monitors the status of each link port, Whether to switch the active and standby relationship of the equipment is determined according to the link state, so as to improve the anti-fault capability of the network in the actual networking process, and the existing technology has made great progress.

[0032] Such as image 3 As shown, the present invention provides a method for notifying downstream devices when the uplink state is switched, and the specific implementation process is as follows:

[0033] In step 301, the VRRP protocol is configured on the ...

Abstract

The invention discloses a method for notifying downstream equipment when switching the uplink status, comprising: configuring a tracking command in the uplink equipment of a route redundant backup system according to existing technology; binding the primary equipment of the route redundant backup system and the core router link as an uplink via the tracking command; binding the primary equipment and a standby equipment link as a downlink via the tracking command. By using the method for notifying downstream equipment when switching the uplink status provided by the invention, when error occurs in the upstream equipment or malfunction occurs in the upstream equipment link, the route redundant backup system can detect the status of the upstream equipment, in order to correctly configure the equipment according to VRRP to realize the primary-standby switching; thus, the open circuit error of the access layer equipment caused by error occurred in the uplink equipment can be prevented, and the anti-error ability of the route redundant backup system in actual network can be enhanced.

Description

technical field [0001] The invention relates to the technical field of route redundancy backup in equipment at the same level, in particular to a method for notifying downstream equipment when an uplink state is switched. Background technique [0002] With the rapid development of network scale and continuous improvement of network quality, network applications have higher and higher requirements for reliability, and various link protection mechanisms have emerged. At present, the VRRP protocol is commonly used in link protection, that is, the virtual routing redundancy protocol, which realizes the backup between devices at the same level of network layer, and mainly completes the basic routing redundancy backup function at the network layer. The election mechanism can quickly realize the backup switch when the equipment fails. For the general configuration, it takes 3-5 seconds, which can basically meet the uninterrupted demand of the business, and there is no special requi...
