华为交换机VRRP+MSTP典型组网配置案例

组网说明：

本案例采用ENSP模拟器来部署VRRP+MSTP，实现主备和网关冗余，其中LSW1作为MSTP的根桥和VRRP的主设备，LSW2作为MSTP的备用根桥和VRRP的备用设备。

配置步骤

配置思路：

1、按照网络拓扑图配置VLAN和IP地址。

2、配置LSW1为MSTP主设备和VRRP主设备。

3、配置LSW2为MSTP备设备和VRRP备设备。

4、配置OSPF实现全网三层互通。

分别查看LSW1、LSW2、LSW3的STP根桥，目前根桥在LSW1：

查看LSW1与LSW2的VRRP状态，目前LSW1是主，LSW2是备。

查看LSW1、LSW2、R1的OSPF邻居状态，已完成建立。

分别查看LSW1、LSW2、R1的路由表，均已学习到对端的业务网段。

PC分别填写IP地址，且能相互PING通。

以PC2为例做冗余测试，在网络正常时，主走LSW1去访问PC1

关闭LSW2的所有接口，模拟LSW2故障，PC2去往PC1走LSW2：

此时LSW2是VRRP主设备。

开启LSW1的所有接口，模拟LSW1恢复使用，业务可以切换到主走LSW1。

从冗余测试的情况来看，VRRP能完成主备切换。

至此，华为交换机VRRP+MSTP典型组网配置案例已完成！
