VRRP虚拟网关实验

下图为VRRP虚拟网关的实验，三台主机分别为PC4、PC5、PC6，实验要求是PC4和PC5之间、PC4和PC6之间，从主AR4路径完成正常通信，同时如果主路出现问题，备AR5替代主的功能继续保障主机间的正常通信。
虚拟网关为192.168.1.254。

第一步：对每台主机的ip地址、子网掩码、网关进行配置。
第二步：对路由器AR6进行设置

[Huawei]sys AR6
[AR6]int g0/0/0
[AR6-GigabitEthernet0/0/0]ip add 192.168.2.254 24
[AR6-GigabitEthernet0/0/0]int g0/0/1
[AR6-GigabitEthernet0/0/1]ip add 10.0.0.2 24
[AR6-GigabitEthernet0/0/1]int g0/0/2
[AR6-GigabitEthernet0/0/2]ip add 20.0.0.2 24
[AR6-GigabitEthernet0/0/2]q
[AR6]ip route-static 192.168.1.0 24 10.0.0.1
[AR6]ip route-static 192.168.1.0 24 20.0.0.1 preference 60    //另一侧的静态路由优先级60

第三步：对路由器AR4进行设置

[Huawei]sys AR4
[AR4]int g0/0/0
[AR4-GigabitEthernet0/0/0]ip add 10.0.0.1 24
[AR4-GigabitEthernet0/0/0]int g0/0/1
[AR4-GigabitEthernet0/0/1]ip add 192.168.1.100 24
[AR4-GigabitEthernet0/0/1]vrrp vrid 1 virtual-ip 192.168.1.254	 //设置虚拟IP地址
[AR4-GigabitEthernet0/0/1]vrrp vrid 1 priority 120	       //优先级120
[AR4-GigabitEthernet0/0/1]vrrp vrid 1 preempt-mode timer delay 30	//延迟抢占30秒
[AR4-GigabitEthernet0/0/1]vrrp vrid 1 track int g0/0/0 reduced 50     //监控上行端口，出现问题，优先级减50
[AR4-GigabitEthernet0/0/1]q	
[AR4]ip route-static 192.168.2.0 24 10.0.0.2

第四步：对路由器AR5进行设置

[Huawei]sys AR5
[AR5]int g0/0/0
[AR5-GigabitEthernet0/0/0]ip add 20.0.0.1 24
[AR5-GigabitEthernet0/0/0]int g0/0/1
[AR5-GigabitEthernet0/0/1]ip add 192.168.1.200 24
[AR5-GigabitEthernet0/0/1]vrrp vrid 1 virtual-ip 192.168.1.254
[AR5-GigabitEthernet0/0/1]q	
[AR5]ip route-static 192.168.2.0 24 20.0.0.2
