Problems solved by technology

When the number of routing links is relatively large, it will occupy a lot of resources of the routing device to calculate new routing links, which will affect the normal processing of other services
At the same time, after the calculation of new routing links is completed, if the number of routing links is relatively large, the time for delivering routing links will be relatively long, causing other services to be interrupted for a long time
In addition, after the routing device returns to normal, the routing table needs to be refreshed to use the equal-cost routing link group to forward data, which occupies a lot of resources of the routing device and affects the execution of other services.

Abstract

The invention provides a routing path determination method and device and a routing device, wherein when a router receives the information to be forwarded, according to the number of the routing linkscapable of normally communicating in a main equivalent link group and the number of the routing links capable of normally communicating in a standby equivalent link group, routing is quickly switchedbetween the main equivalent link group and the standby equivalent link group; and when the main equivalent link group does not have the routing link capable of normally communicating, the resources of the routing device do not need to be occupied to recalculate the routing link and issue a new routing link, so that the execution of other services is not influenced, the utilization rate of the resources of the routing device is improved, and the information forwarding efficiency is improved. In addition, according to the technical scheme, after the routing link for recovering normal communication exists in the main equivalent link group, the routing table does not need to be refreshed again to forward data by using the main equivalent link group, so that the resource utilization rate of the routing device and the information forwarding efficiency are further improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a method and device for determining a routing path, and a routing device. Background technique [0002] An equal-cost routing link group is generally formed by directly connecting multiple Layer 3 interfaces of two routing devices through switches. The existence of equal-cost routing link groups can not only realize load sharing and improve the forwarding speed of information, but also can quickly switch routes when one of the routing links fails, and use other normal communication routing links to carry out information transmission. Forwarding ensures the stability of information forwarding. [0003] Since the equal-cost routing link group is formed by relying on two routing devices, if one of the routing devices fails, all the routing links in the equal-cost routing link group will not be able to forward data normally. At this point, it is necessary to r...
