Problems solved by technology

[0004] However, in actual network communication, there are situations where LSA or LSP may be deleted incorrectly, for example, the failure of the faulty device’s lifetime timer causes the LSA or LSP to age too quickly, or for example, there is an error in the device program, which causes the entire network to flood delete the LSA or LSP
[0005] In the prior art, when an LSA or LSP is deleted by mistake, the device that receives the notification of deleting the LSA or LSP will immediately delete the LSA or LSP and recalculate the route until the deleted LSA or LSP is regenerated. If the faulty device periodically deletes the LSA or LSP incorrectly, it will cause route flapping, resulting in loss of service traffic

Abstract

Provided are a route updating method and network equipment therefor. The method comprises: receiving, by first network equipment, a first message sent by second network equipment, the first message carrying state information of a first link, ageing time carried by the first message having reached maximum ageing time; if the second network equipment is in an abnormal state, initiating, by the first network equipment, a first timer at starting time for receiving the first message, wherein a timing duration of the first timer is a first duration, and after the first timer expires, the first message participates in route calculation. Embodiments of the present invention can reduce the influence on route processing resulting from carrying of a message for indicating to delete link state information generated by an equipment fault, thus reducing route oscillation and traffic loss.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for processing messages and network equipment thereof. Background technique [0002] Open Shortest Path First Protocol (English: Open Shortest Path First, abbreviated: OSPF) and Intermediate System to System Protocol (English: Intermediate System to Intermediate System, abbreviated: IS-IS) belong to the Interior Gateway Protocol (English: Interior Gateway Protocol, abbreviated : IGP), the interior gateway protocol is a link state protocol, which establishes a network topology by sending Hello messages between devices to establish adjacencies hop by hop, in which each adjacency is bidirectional and has a metric value Then send the link state announcement (English: Link State Advertisement, abbreviation: LSA) or (English: Link State Protocol Data Unit, abbreviation: LSP) to send the local link topology and routing information to each remote device , OSPF or IS-IS uses the shorte...
