VRRP基本配置環境拓撲：
VRRP基本配置環境中的IP位址規劃：
在路由器接口添加VRRP配置：
[AR1]interface g0/0/0
[AR1-GigabitEthernet0/0/0]vrrp vrid 10 virtual-ip 10.10.10.254
[AR1-GigabitEthernet0/0/0]vrrp vrid 10 priority 150
[AR2]interface g0/0/0
[AR2-GigabitEthernet0/0/0]vrrp vrid 10 virtual-ip 10.10.10.254
檢查VRRP狀态：
[AR1]display vrrp brief
Total:1 Master:1 Backup:0 Non-active:0
VRID State Interface Type Virtual IP
----------------------------------------------------------------
10 Master GE0/0/0 Normal 10.10.10.254
[AR2]display vrrp brief
Total:1 Master:0 Backup:1 Non-active:0
VRID State Interface Type Virtual IP
----------------------------------------------------------------
10 Backup GE0/0/0 Normal 10.10.10.254
檢視VRRP版本：
[AR1]display vrrp protocol-information
VRRP protocol information is shown as below:
VRRP protocol version : V2
Send advertisement packet mode : send v2 only
在PC10上驗證VRRP的配置效果：
