中小型网络完全配置实例vrrp和mstp

中小型网络完全配置实例（VRRP_MSTP）

实验均是在dynamips下完成的，拓扑图是在visio2007里完成的。

在这里，晚生用三个三层核心交换机相互连接，这样的好处是内网数据完全可以在

SW2-SW3之间完成，同时也起到了路由配备的功能：

路由一：

SW5<->SW3<->SW2<->SW4<->SW5

路由二：

SW5<->SW3<->SW1<->SW2<->SW4

当然有了备份路由就有了负载均衡的问题。

在这个实验中，内网间的数据我没有考虑，主要是到外网的上传与下载我进行了负载均衡（用了了MSTP与VRRP）。

VRRP是在SW2SW3上实现的。

特别声明：

由于dynimaps里不能做mstp。

我就在每一个vlan里自行指定了root设备，我想原理都是一样的。

下面是SW1的配置：
