1、概述
1.1 浮动静态路由
浮动静态路由是一种特殊的静态路由,通过配置去往相同的目的网段,但优先级不同的静态路由,以保证在网络中优先级较高的路由,即主路由失效的情况下,提供备份路由,但是在正常情况下,备份路由不会出现在路由表中。
1.2 负载均衡
当数据有多条可选路径前往同一目的网络,可以通过配置相同优先级和开销的静态路由实现负载均衡,使得数据的传输均衡的分配到多条路径上,从而实现数据的分流,减轻单条路径负载过重的效果,而当其中某一条路径失效时,其他路径仍然能够正常传输数据,也起到了冗余的作用。
2、配置浮动路由及负载均衡
2.1 实验内容
2.2 实验拓扑
2.3 实验编址
2.4 实验步骤
step1:按照实验编址表配置好各个设备的地址及相关信息,并测试各直连链路的连通性,通过测试发现各直连链路都可联通。

step2:实现总部和各分部,各分部之间互通
step3:使用pc1 ping pc2 测试连通性可以ping通,总部和分部之间也能通信
step4:使用命令查看pc1到pc2的数据经过哪些网口,发现他走的是R1>R2>R3的路线
