Embodiment Construction

[0051] For the shock of route deletion and route addition in the forwarding platform in the prior art, and when the recursive BGP route capacity is large, the disconnection time of the last BGP route may be too long. Although the process from eth0 layer 3 down to OSPF component re-delivering route R0 update to the routing platform may not take long, but the BGP routing on the forwarding plane still occurs: the shock of deletion and addition. This is because: once the routing platform detects that the OSPF route R0 has changed from active to inactive, and the BGP route is recursive to R0, it will find that R1~R10000 are not active, and then notify the forwarding plane to delete R1~R10000.

[0052] In view of the above-mentioned problems existing in the prior art, the routing management method provided by the embodiment of the present invention is applied to a routing system including a routing platform and a forwarding platform, and the routing platform stores a BGP route and a ...

Abstract

The invention discloses a routing management method and device, the method is applied to a routing system comprising a routing platform and a forwarding platform, and the routing platform stores a border network protocol BGP route and a first route; the method comprises the following steps: when the routing platform monitors that the first routing is changed from an active state to an inactive state, starting a pseudo-active state timer, and setting the first routing state as the pseudo-active state so as to keep a BGP routing recurding to the first routing unchanged; when the pseudo active state timer does not exceed a preset duration, the routing platform receives an update message of the first route, and sends an announcement of updating the first route to the forwarding platform; and the forwarding platform updates the first route and the BGP route recurding to the first route according to the notification. According to the embodiment of the invention, the problem of long-time cutoff caused by routing oscillation in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a routing management method and device. Background technique [0002] A network is composed of network devices connected one by one. Routing is the basis of network devices. Only when there is a suitable route can the network be connected. In the network equipment, there are configured static routes and routing protocols to generate routes. Routing protocols include: Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (Open Shortest Path) First, OSPF), Routing Information Protocol (Routing Information Protocol, RIP), Border Gateway Protocol (Border Gateway Protocol, BGP) and so on. [0003] For details, please refer to figure 1 , the routing system in the network equipment, logically includes: routing protocol, routing platform and forwarding platform. The routing protocol is responsible for generating original routes and delivering the orig...
