浮动静态路由及负载均衡

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。
