步驟三.配置VRRP，實(shí)現(xiàn)網(wǎng)關(guān)冗余
S1配置VRRP，使用VRRP組1，默認(rèn)優(yōu)先級為100，實(shí)驗(yàn)中定義為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上測試他們與模擬的Internet服務(wù)器之間的通訊是否正常。

wKiom1O41XfQzNtzAAHMKUG_3tI540.jpg
在S1上查看VRRP當(dāng)前的狀態(tài)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

Virtual MAC : 0000-5e00-0101

Create time : 2014-07-03 11:58:33 UTC-08:00
Last change time: 2014-07-03 11:58:37 UTC-08:00
當(dāng)前R2與R3都是通過S1將數(shù)據(jù)包發(fā)送至internet的。關(guān)閉S1的vlanif 1接口，然后測試網(wǎng)絡(luò)是否正常切換。
[S1]interface vlanif 1
[S1-Vlanif1]shutdown
在R2與R3上測試他們與模擬Internet服務(wù)器之間的通訊是否正常。

wKiom1O41ZTzMKKhAAHhhCqoXIg058.jpg
此時相當(dāng)于S1設(shè)備停止工作，查看S1與S2的VRRP狀態(tài)。
[S1]disp vrrp
Vlanif1 | Virtual Router 1

Last change time : 2014-07-03 12:01:21UTC-08:00
步驟四.跟蹤接口狀態(tài)
重新打開S1的vlanif1接口，并配置S1、S2蹤它們的G0/0/1、G0/0/2接口。
[S1]interfacevlanif 1
[S1-Vlanif1]undoshutdown
查看S1的vrrp狀態(tài)。
[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
此時R2與R3通過S1發(fā)送數(shù)據(jù)給internet。如果關(guān)閉S1的G0/0/1接口，或關(guān)閉R1的G0/0/1接口，網(wǎng)絡(luò)將無法自動切換到通過S2發(fā)送數(shù)據(jù)給internet。
關(guān)閉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參數(shù)可以顯示簡略信息。
測試R2與internet的連通性。
顯示無法正常通信
重新打開S1的G0/0/1接口
[S1]interfaceg0/0/1
[S1-GigabitEthernet0/0/1]undoshutdown
S1和S2上配置VRRP的接口跟蹤，定義跟蹤G0/0/1接口，如果接口被關(guān)閉，則由此岸及降低10.這樣的情況下，S2將搶占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
此時，測試網(wǎng)絡(luò)的連通性。
網(wǎng)絡(luò)正常時，R2可以與internet服務(wù)器通信。
關(guān)閉S1的G0/0/1接口
[S1]interfaceg0/0/1
[S1-GigabitEthernet0/0/1]shutdown
測試R2與internet服務(wù)器之間的連通性。
通訊依然正常，查看S1的vrrp狀態(tài)。
[S1]dis vrrp
Vlanif1 | Virtual Router 1
State : Backup
Virtual IP : 10.0.123.1
Master IP : 10.0.123.3
