网络运维学员作品-路由交换项目

项目一：使用eNSP搭建实验环境，配置单臂路由实现VLAN 10与VLAN 20互通

首先配置交换机：

1. [Huawei]vlan batch 10 20

2. [Huawei]int e0/0/1

3. [Huawei-Ethernet0/0/1]port link-t access

4. [Huawei-Ethernet0/0/1]port default vlan 10

5. [Huawei-Ethernet0/0/1]int e0/0/2

6. [Huawei-Ethernet0/0/2]port link-t access

7. [Huawei-Ethernet0/0/2]port default vlan 20

8. [Huawei]int g0/0/1

9. [Huawei-GigabitEthernet0/0/1]port link-t trunk

10. [Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20

然后配置路由器：

1. [Huawei]int g0/0/1.1

2. [Huawei-GigabitEthernet0/0/1.1]dot1q termination vid 10

3. [Huawei-GigabitEthernet0/0/1.1]ip add 24

4. [Huawei-GigabitEthernet0/0/1.1]arp broadcast enable

5. [Huawei-GigabitEthernet0/0/1.1]int g0/0/1.2

6. [Huawei-GigabitEthernet0/0/1.2]dot1q termination vid 20

7. [Huawei-GigabitEthernet0/0/1.2]ip add 24

8. [Huawei-GigabitEthernet0/0/1.2]arp broadcast enable

全部配置完成之后使用ping命令进行测试，证明PC1可以ping通PC2

项目二：使用多台交换机实现多交换机VLAN间通信

首先，在二层交换机SW1和SW2上配置VLAN：

1. [SW1]vlan 2

2. [SW1]vlan 3

3. [SW1]interface Ethernet0/0/1

4. [SW1-Ethernet0/0/1]port link-type access

5. [SW1-Ethernet0/0/1]port default vlan 1

6. [SW1]interface Ethernet0/0/2

7. [SW1-Ethernet0/0/2]port link-type access

8. [SW1-Ethernet0/0/2]port default vlan 2

9. [SW1]interface Ethernet0/0/3

10. [SW1-Ethernet0/0/3]port link-type access

11. [SW1-Ethernet0/0/3]port default vlan 3

12. [SW1]int g0/0/1

13. [SW1-GigabitEthernet0/0/1]port link-type trunk

14. [SW1-GigabitEthernet0/0/1]port trunk allow-pass vlan all

15. [SW2]vlan 4

21. [SW2-Ethernet0/0/2]port link-type access

22. [SW2-Ethernet0/0/2]port default vlan 5

23. [SW2]int g0/0/1

24. [SW2-GigabitEthernet0/0/1]port link-type trunk

25. [SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan all

然后配置三层交换机：

1. [SW3]vlan batch 1 to 5

2. [SW3]int g0/0/1

3. [SW3-GigabitEthernet0/0/1]port link-type trunk

4. [SW3-GigabitEthernet0/0/1]port trunk allow-pass vlan all

5. [SW3]int g0/0/2

6. [SW3-GigabitEthernet0/0/2]port link-type trunk

7. [SW3-GigabitEthernet0/0/2]port trunk allow-pass vlan all

8. [SW3]int Vlanif 1

13. [SW3-Vlanif3]ip add 24

14. [SW3]int Vlanif 4

15. [SW3-Vlanif1]ip add 24

16. [SW3]int Vlanif 5

17. [SW3-Vlanif2]ip add 24

配置完成后测试PC机之间是否可以ping通
