IPV6之VRRP典型组网配置案例
IPV6之VRRP典型组网配置案例 : https://mp.weixin.qq.com/s/AQEIqA2vijRi1Dhj2I7uRw
组网及说明
组网说明：
本案例采用H3C HCL模拟器来模拟IPV6 VRRP典型组网配置。为了确保网络的冗余，将SW2和SW3开启VRRP作为网关冗余。SW2为主设备，SW3为备用设备。SW2、SW3与R1的互联采用ospfv3路由协议互通。当断开SW2的GI1/0/2上联口是，物理机能走SW3方向去往R1。
配置步骤
- 按照网络拓扑图正确配置IP地址和VLAN划分
- SW2和SW3配置VRRP
- SW2配置track，方便VRRP的检测与切换
- SW2、SW3、R1运行OSPFv3路由协议

[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！
