步骤三.配置VRRP，实现网关冗余
S1配置VRRP，使用VRRP组1，默认优先级为100，实验中定义为105.
[S1]interface vlanif 1
[S1-Vlanif1]vrrp vrid 1 virtual-ip10.0.123.1
[S1-Vlanif1]vrrp vrid 1 priority 105
[S2]interface vlanif 1
[S2-Vlanif1]vrrp vri
[S2-Vlanif1]vrrp vrid 1 vir
[S2-Vlanif1]vrrp vrid 1 virtual-ip10.0.123.1
配置完成后，在R2和R3上测试他们与模拟的Internet服务器之间的通讯是否正常。

在S1上查看VRRP当前的状态信息。
[S1]disp vrrp
Vlanif1 | Virtual Router 1
State : Master
Virtual IP : 10.0.123.1
Master IP : 10.0.123.2
PriorityRun : 105
PriorityConfig : 105
MasterPriority : 105
Preempt : YES Delay Time : 0 s
TimerRun : 1 s
TimerConfig : 1 s
Auth type : NONE
Virtual MAC : 0000-5e00-0101
Check TTL : YES
Config type : normal-vrrp
Create time : 2014-07-03 11:58:33 UTC-08:00
Last change time: 2014-07-03 11:58:37 UTC-08:00
当前R2与R3都是通过S1将数据包发送至internet的。关闭S1的vlanif 1接口，然后测试网络是否正常切换。
[S1]interface vlanif 1
[S1-Vlanif1]shutdown
在R2与R3上测试他们与模拟Internet服务器之间的通讯是否正常。

此时相当于S1设备停止工作，查看S1与S2的VRRP状态。
[S1]disp vrrp

Last change time : 2014-07-03 12:01:21UTC-08:00
步骤四.跟踪接口状态
重新打开S1的vlanif1接口，并配置S1、S2踪它们的G0/0/1、G0/0/2接口。
[S1]interfacevlanif 1
[S1-Vlanif1]undoshutdown
查看S1的vrrp状态。
[S1]displ vrrp
Vlanif1 | Virtual Router 1
State : Master
Virtual IP : 10.0.123.1
Master IP : 10.0.123.2
PriorityRun : 105
PriorityConfig : 105
MasterPriority : 105
Preempt : YES Delay Time : 0 s
TimerRun : 1 s
TimerConfig : 1 s
Auth type : NONE
Virtual MAC : 0000-5e00-0101
Check TTL : YES
Config type : normal-vrrp
Create time : 2014-07-03 11:58:33 UTC-08:00
Last change time : 2014-07-03 12:21:05UTC-08:00
此时R2与R3通过S1发送数据给internet。如果关闭S1的G0/0/1接口，或关闭R1的G0/0/1接口，网络将无法自动切换到通过S2发送数据给internet。
关闭S1的G0/0/1接口
[S1]interfaceg0/0/1
[S1-GigabitEthernet0/0/1]shutdown
[S1]dis vrrp brief
VRID State Interface Type Virtual IP
----------------------------------------------------------------
1 Master Vlanif1 Normal 10.0.123.1
----------------------------------------------------------------
Total:1 Master:1 Backup:0 Non-active:0
注：使用brief参数可以显示简略信息。
测试R2与internet的连通性。
显示无法正常通信
重新打开S1的G0/0/1接口
[S1]interfaceg0/0/1
[S1-GigabitEthernet0/0/1]undoshutdown
S1和S2上配置VRRP的接口跟踪，定义跟踪G0/0/1接口，如果接口被关闭，则由此岸及降低10.这样的情况下，S2将抢占S1的VRRP主角色
[S1]interfacevlanif 1
[S1-Vlanif1]vrrpvrid 1 track interface g0/0/1 reduced 10
[S2]interfacevlanif 1
[S2-Vlanif1]vrrpvrid 1 track interface g0/0/2 reduced 10
此时，测试网络的连通性。
网络正常时，R2可以与internet服务器通信。
关闭S1的G0/0/1接口
[S1]interfaceg0/0/1
[S1-GigabitEthernet0/0/1]shutdown
测试R2与internet服务器之间的连通性。
通讯依然正常，查看S1的vrrp状态。
[S1]dis vrrp
Vlanif1 | Virtual Router 1
State : Backup
Virtual IP : 10.0.123.1
Master IP : 10.0.123.3
PriorityRun : 95
