一、配PC的IP、子网掩码、网关

二、配路由交换机接口的IP、VLAN、VRRP

  • SW1

    <Huawei>u t m
    <Huawei>sys
    [Huawei]sys SW1
    [SW1]vlan 10
    [SW1-vlan10]quit
    [SW1]port-group group-member g0/0/1 to g0/0/4	
    [SW1-port-group]port link-type access 
    [SW1-port-group]port default vlan 10
    [SW1-port-group]return
    <SW1>save
    
  • AR1

    <Huawei>u t m
    <Huawei>sys
    [Huawei]sys AR1
    [AR1]int g0/0/0
    [AR1-GigabitEthernet0/0/0]ip a 192.168.1.251 24
    [AR1-GigabitEthernet0/0/0]int g0/0/1
    [AR1-GigabitEthernet0/0/1]ip a 192.168.13.1 24
    [AR1-GigabitEthernet0/0/1]quit
    [AR1]int g0/0/0
    [AR1-GigabitEthernet0/0/0]vrrp vrid 1 virtual-ip 192.168.1.254
    [AR1-GigabitEthernet0/0/0]vrrp vrid 1 priority 130
    [AR1-GigabitEthernet0/0/0]quit
    [AR1]ip route-static 192.168.2.0 24 192.168.13.3
    [AR1]quit
    <AR1>save
    
  • AR2

    <Huawei>u t m
    <Huawei>sys
    [Huawei]sys AR2
    [AR2]int g0/0/0
    [AR2-GigabitEthernet0/0/0]ip a 192.168.1.252 24
    [AR2-GigabitEthernet0/0/0]vrrp vrid 1 virtual-ip 192.168.1.254
    [AR2-GigabitEthernet0/0/0]int g0/0/1
    [AR2-GigabitEthernet0/0/1]ip a 192.168.23.1 24
    [AR2-GigabitEthernet0/0/1]quit
    [AR2]ip route-static 192.168.2.0 24 192.168.23.3
    [AR2]quit
    <AR2>save
    
  • AR3

    <Huawei>u t m
    <Huawei>sys
    [Huawei]sys AR3
    [AR3]int g 0/0/0
    [AR3-GigabitEthernet0/0/0]ip a 192.168.13.3 24
    [AR3-GigabitEthernet0/0/0]int g0/0/1
    [AR3-GigabitEthernet0/0/1]ip a 192.168.23.3 24
    [AR3-GigabitEthernet0/0/1]int g0/0/2
    [AR3-GigabitEthernet0/0/2]ip a 192.168.2.254 24
    [AR3-GigabitEthernet0/0/2]quit
    [AR3]ip route-static 192.168.1.0 24 192.168.23.1 preference 70
    [AR3]quit
    <AR3>save
    

三、拓展:上行接口监控(上行链路跟踪)

  • AR1

    [R1]int g0/0/0
    [AR1-GigabitEthernet0/0/0]vrrp vrid 10 track int g0/0/1 reduced 50
    

    配置 VRRP 跟踪功能,监视接口 g0/0/1 的状态。如果该接口故障VRRP 的优先级将减少 50
