### 一、配PC的IP、子网掩码、网关

### 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

     3  192.168.30.2   63 ms  47 ms  31 ms
     4  192.168.40.1   94 ms  78 ms  78 ms
     ```

   - **PC4 → PC2**

     ```
     PC4>ping 192.168.10.2
     
     Ping 192.168.10.2: 32 data bytes, Press Ctrl_C to break
     Request timeout!
     From 192.168.10.2: bytes=32 seq=2 ttl=125 time=78 ms

     From 192.168.10.2: bytes=32 seq=5 ttl=125 time=78 ms
     
     --- 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
     ```

     ```
     PC4>tracert 192.168.10.2
     
     traceroute to 192.168.10.2, 8 hops max(ICMP), press Ctrl+C to stop

     4  192.168.10.2   94 ms  78 ms  94 ms
     ```

2. **冗余测试**

   - **PC1 → PC3**
