关键词：策略路由摘 要：目前越来越多的网吧对网络的可靠性稳定性要求越来越高，本文主要介绍AR宽带路由器基于策略路由负载分担的应用方法和配置步骤。 1 介绍1.1 特性简介目前网吧对网络的可靠性和稳定性要求越来越高，一般网吧与运营商都有两条线路保证一条线路出现故障时能够有另一条链路作为备份。当两条线路都正常时为了减少一条线路流量压力，将流量平均分配到另外一条线路，这样提高了网络速度。当一条链路出现故障接口DOWN掉时，系统自动将流量全部转到另一条线路转发，这样提高了网络的稳定性、可靠性。满足网吧对业务要求不能中断这种需求，确保承载的业务不受影响。2 使用指南2.1 使用场合本特性可以用在双链路的组网环境内...
