一、配PC的IP、子网掩码、DNS

二、配路由的IP

  • AR1

    <Huawei>u t m

    <Huawei>sy

    [Huawei]sy AR1

    [AR1]int g 0/0/0

    [AR1-GigabitEthernet0/0/0]ip a 192.168.10.254 24

    [AR1-GigabitEthernet0/0/0]int g 0/0/1

    [AR1-GigabitEthernet0/0/1]ip a 192.168.20.1 24

    [AR1-GigabitEthernet0/0/1]int g 0/0/2

    [AR1-GigabitEthernet0/0/2]ip a 192.168.60.2 24

  • AR2

    <Huawei>u t m

    <Huawei>sy

    [Huawei]sy AR2

    [AR2]int g 0/0/0

    [AR2-GigabitEthernet0/0/0]ip a 192.168.20.2 24

    [AR2-GigabitEthernet0/0/0]int g 0/0/1

    [AR2-GigabitEthernet0/0/1]ip a 192.168.30.1 24

  • AR3

    <Huawei>u t m

    <Huawei>sy

    [Huawei]sy AR3

    [AR3]int g 0/0/0

    [AR3-GigabitEthernet0/0/0]ip a 192.168.40.254 24

    [AR3-GigabitEthernet0/0/0]int g 0/0/1

    [AR3-GigabitEthernet0/0/1]ip a 192.168.30.2 24

    [AR3-GigabitEthernet0/0/1]int g 0/0/2

    [AR3-GigabitEthernet0/0/2]ip a 192.168.50.1 24

  • AR4

    <Huawei>u t m

    <Huawei>sy

    [Huawei]sy AR4

    [AR4]int g 0/0/0

    [AR4-GigabitEthernet0/0/0]ip a 192.168.60.1 24

    [AR4-GigabitEthernet0/0/0]int g 0/0/1

    [AR4-GigabitEthernet0/0/1]ip a 192.168.50.2 24

三、配置静态路由

  • AR1

    [AR1]ip route-static 192.168.30.0 24 192.168.20.2

    [AR1]ip route-static 192.168.40.0 24 192.168.20.2 preference 30

    [AR1]ip route-static 192.168.40.0 24 192.168.60.1

    [AR1]ip route-static 192.168.50.0 24 192.168.60.1

  • AR2

    [AR2]ip route-static 192.168.10.0 24 192.168.20.1

    [AR2]ip route-static 192.168.40.0 24 192.168.30.2

  • AR3

    [AR3]ip route-static 192.168.10.0 24 192.168.30.1

    [AR3]ip route-static 192.168.10.0 24 192.168.50.2 preference 30

    [AR3]ip route-static 192.168.20.0 24 192.168.30.1

    [AR3]ip route-static 192.168.60.0 24 192.168.50.2

  • AR4

    [AR4]ip route-static 192.168.10.0 24 192.168.60.2

    [AR4]ip route-static 192.168.40.0 24 192.168.50.1

四、连通性测试

  1. 全局测试

    • PC1 → PC3

      PC1>ping 192.168.40.1

      Ping 192.168.40.1: 32 data bytes, Press Ctrl_C to break

      From 192.168.40.1: bytes=32 seq=1 ttl=125 time=62 ms

      From 192.168.40.1: bytes=32 seq=2 ttl=125 time=63 ms

      From 192.168.40.1: bytes=32 seq=3 ttl=125 time=78 ms

      From 192.168.40.1: bytes=32 seq=4 ttl=125 time=94 ms

      From 192.168.40.1: bytes=32 seq=5 ttl=125 time=78 ms

      --- 192.168.40.1 ping statistics ---

      5 packet(s) transmitted

      5 packet(s) received

      0.00% packet loss

      round-trip min/avg/max = 62/75/94 ms

      PC1>tracert 192.168.40.1

      traceroute to 192.168.40.1, 8 hops max(ICMP), press Ctrl+C to stop

      1 192.168.10.254 62 ms 47 ms 47 ms

    • PC4 → PC2

      PC4>ping 192.168.10.2

      Ping 192.168.10.2: 32 data bytes, Press Ctrl_C to break

      Request timeout!

      --- 192.168.10.2 ping statistics ---

      5 packet(s) transmitted

      4 packet(s) received

      20.00% packet loss

      round-trip min/avg/max = 0/78/78 ms
