Problems solved by technology

[0004] That is to say, when a link failure occurs in the network, the network devices on the fault transmission path perform route convergence serially, and the route convergence time of the entire network is relatively long.

Abstract

The invention discloses a route processing method, which is used for enabling network equipment in a network system to carry out route convergence in parallel and reducing the route convergence time. The first network device obtains first information, the first information indicates a fault of a first link, and the first link is a link between any two network devices in a network system to which the first network device belongs; the first network device sends first information to a second network device through a BGP, for example, sends a link fault message to the second network device through the BGP, wherein the link fault message carries the first information, and the second network device is a neighbor device of the first network device; the first network device determines an unreachable route in a routing table of the first network device according to the first information and the topology of the network system, wherein a path corresponding to the unreachable route comprises a first link; and the first network device marks the inaccessible route as invalid.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a routing processing method and related equipment. Background technique [0002] At present, in some large-scale data centers, the routing protocol adopted is usually a border gateway protocol (Border Gateway Protocol, BGP) directly connected hop by hop, that is, BGP directly connected by hop by hop is run between network devices in the data center. When a BGP route is propagated between network devices, the network device changes the next hop of the BGP route hop by hop. [0003] In a data center running BGP, each network device only advertises the local optimal route to neighboring devices. When a link failure occurs in the network, the affected network device will first calculate the local optimal route. If it is determined after local optimal route calculation that there is no local backup path to the destination route prefix, the network device sends a...
