组网案例:双链路出口使用策略路由的设置方法

发布时间:2013-03-06 12:09

【组网需求】
 
1、XX市某公司,分部在区县,总部在主城区,他们之间通过两条E1专线相连,其业务在这两条线路之间负载分担,现A业务流量太大,故将两条专线改成主备方式,专线1作为A业务的专用链路及其他业务的备份,专线2作为其他业务的主链路及A业务的备份。
 
2、拓扑和软件
 
本文实验采用的交换机是H3C模拟器,在华三官网论坛上去下载,里面有非常详细的使用说明以及自定义拓扑的方法。
 
3、组网需求

实验中假设的一个Loopback地址在实际应用中可以看成是一个网段。
假设192.168.36.1只和192.168.20.1通信
192.168.37.1只和192.168.21.1
 
当源地址是192.168.36.1去192.168.20.1时,经R2时下一跳是172.16.1.1
192.168.37.1去往192.168.21.1下一跳为172.16.1.5 ,R3上同理作回包的策略路由。
