Abstract

The invention provides a method and apparatus for suppressing neighbor oscillation. The method comprises the following steps: a first router obtains a neighbor state change dynamic state between a second router which establishes a neighbor relationship with the first router; the first router adds one to a neighbor penalty value when the neighbor state change dynamic state is changed from a normal state to a fault state each time; when the increased neighbor penalty value is greater than a preset suppression threshold value, the first router sets the neighbor relationship as a suppression state. The method and apparatus solve a problem that an unstable neighbor state causes routing oscillation of a local routing table in the prior art so as to achieve an effect of saving valuable bandwidth resources and CPU resources.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for suppressing neighbor oscillation. Background technique [0002] Routing protocols are mainly divided into two types, one is the distance vector routing algorithm, and the other is the link state routing algorithm. Distance vector routing algorithms include Routing Information Protocol (Routing Information Protocol, referred to as RIP), Border Gateway Protocol (Border Gateway Protocol, referred to as BGP), link state routing algorithms include Open Shortest Path First (Open Shortest Path First, referred to as OSPF), Intermediate System-to-Intermediate System (Intermediate System-to-Intermediate System, referred to as ISIS). [0003] Routing protocols (except the RIP protocol) all use the HELLO message mechanism (the HELLO message carries local relevant attribute information. Check the validity. If each parameter matches, it will record the neighbor relat...
