[R1]

物理机设置IPV6地址：

物理机能PING通4：：1

路由追踪，走SW2方向去往4::1

关闭SW2的GI 1/0/2端口：

[SW2]int gi 1/0/2

[SW2-GigabitEthernet1/0/2]shutdown

查看SW2和SW3的VRRP状态：

SW2的VRRP状态为backup

SW3的VRRP状态为main

此时物理机依然可以PING通4：：1

使用trecert -d 4::1，物理机去往4：：1已经走SW3方向：

由以上测试结果得知，VRRP可以正常切换，同时在切换后，VLAN10的流量可以正常走SW3方向去往R1。

至此，IPV6之VRRP典型组网配置案例已完成！
