VRRP基本配置拓扑
一、完成PC的基本配置
PC1、PC2、PC3基本配置
二、配置AR1、AR2、AR3各接口的ip地址
1、AR1
[Huawei]sysname AR1
[AR1]INT G0/0/0
[AR1-GigabitEthernet0/0/0]IP address 10.10.10.253 24
[AR1-GigabitEthernet0/0/0]INT G0/0/1
[AR1-GigabitEthernet0/0/1]ip address 192.168.0.2 30
2、AR2
[Huawei]sysname AR2
[AR2]int g0/0/0
[AR2-GigabitEthernet0/0/0]ip address 10.10.10.252 24
[AR2-GigabitEthernet0/0/0]int g0/0/1
[AR2-GigabitEthernet0/0/1]ip address 192.168.0.6 30
3、AR3
[Huawei]sysname AR3
[AR3]int g0/0/0
[AR3-GigabitEthernet0/0/0]ip address 192.168.0.1 30
[AR3-GigabitEthernet0/0/0]int g0/0/1
[AR3-GigabitEthernet0/0/1]ip address 192.168.0.5 30
[AR3-GigabitEthernet0/0/0]int g0/0/2
[AR3-GigabitEthernet0/0/2]ip address 192.168.0.254 24
4、查看路由器各接口的ip地址
AR1
AR2
AR3
三、在AR1、AR2、AR3运行OSPF协议，学习到图中拓扑所包含的所有路由
1、AR1
[AR1]ospf
[AR1-ospf-1]area 0
[AR1-ospf-1-area-0.0.0.0]net
[AR1-ospf-1-area-0.0.0.0]network 192.168.0.0 0.0.0.255
[AR1-ospf-1-area-0.0.0.0]network 10.10.10.0 0.0.0.255
2、AR2
[AR2]ospf
[AR2-ospf-1]area 0
[AR2-ospf-1-area-0.0.0.0]network 192.168.0.0 0.0.0.255
[AR2-ospf-1-area-0.0.0.0]network 10.10.10.0 0.0.0.255
3、AR3
[AR3]ospf
[AR3-ospf-1]area 0
[AR3-ospf-1-area-0.0.0.0]network 192.168.0.0 0.0.0.255
4、查看路由器通过ospf协议学习到的路由表
AR1
AR2
AR3
四、配置VRRP虚拟网关地址
1、将PC1去往PC3的VRRP的虚拟路由器ID（VRID）设置为10，并且把网关路由器的IP地址设置为10.10.10.254，并让AR1成为VRRP的主用路由器
[AR1]int 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]int g0/0/0
[AR2-GigabitEthernet0/0/0]vrrp vrid 10 virtual-ip 10.10.10.254
2、将PC2去往PC3的VRRP的虚拟路由器ID（VRID）设置为20，并且把网关路由器的IP地址设置为10.10.10.251,让AR2成为VRRP的主用路由器,且它们之间需要使用密码进行通信。
[AR2]int g0/0/0
[AR2-GigabitEthernet0/0/0]vrrp vrid 20 virtual-ip 10.10.10.251
[AR2-GigabitEthernet0/0/0]vrrp vrid 20 priority 150
[AR2-GigabitEthernet0/0/0]vrrp vrid 20 authentication-mode simple plain 123456
[AR1]int g0/0/0
[AR1-GigabitEthernet0/0/0]vrrp vrid 20 virtual-ip 10.10.10.251
[AR1-GigabitEthernet0/0/0]vrrp vrid 20 authentication-mode simple plain 123456
3、配置VRRP追踪上行链路
[AR1-GigabitEthernet0/0/0]vrrp vrid 10 track int g0/0/1 reduced 100
[AR2-GigabitEthernet0/0/0]vrrp vrid 20 track int g0/0/1 reduced 100
4、查看AR1、AR2上VRRP的状态
AR1
AR2
五、测试连通性
PC1访问PC3
PC2访问PC3
