26. [SW2-GigabitEthernet0/0/13]port trunk allow-pass vlan 1 to 20 27. [SW2]int g0/0/14

28. [SW2-GigabitEthernet0/0/14]port link-type trunk

29. [SW2-GigabitEthernet0/0/14]port trunk allow-pass vlan 1 to 20 30. 31. SW3：

32. [SW3]vlan batch 2 to 20 33. [SW3]int g0/0/1

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

35. [SW3-GigabitEthernet0/0/1]port trunk allow-pass vlan 1 to 20 36. [SW3]int g0/0/13

37. [SW3-GigabitEthernet0/0/13]port link-type trunk

38. [SW3-GigabitEthernet0/0/13]port trunk allow-pass vlan 1 to 20 39. [SW3]int g0/0/23

40. [SW3-GigabitEthernet0/0/23]port link-type trunk

41. [SW3-GigabitEthernet0/0/23]port trunk allow-pass vlan 1 to 2 42. 43. SW4：

44. [SW4]vlan batch 2 to 20 45. [SW4]int g0/0/1

46. [SW4-GigabitEthernet0/0/1]port link-type trunk

47. [SW4-GigabitEthernet0/0/1]port trunk allow-pass vlan 1 to 20 48. [SW4]int g0/0/14

49. [SW4-GigabitEthernet0/0/14]port link-type trunk

50. [SW4-GigabitEthernet0/0/14]port trunk allow-pass vlan 1 to 20 51. [SW4]int g0/0/24

52. [SW4-GigabitEthernet0/0/24]port link-type trunk

53. [SW4-GigabitEthernet0/0/24]port trunk allow-pass vlan 1 to 2

配置mstp，定义vlan1-10属于instance 1，vlan11-20属于instance 2

[plain] view plain copy

1. SW1：

2. [SW1]stp mode mstp

3. [SW1]stp region-configuration 4. [SW1-mst-region]region-name RG1

5. [SW1-mst-region]instance 1 vlan 1 to 10 6. [SW1-mst-region]instance 2 vlan 11 to 20 7. [SW1-mst-region]active region-configuration 8. SW2：

9. [SW2]stp mode mstp

10. [SW2]stp region-configuration 11. [SW2-mst-region]region-name RG1

12. [SW2-mst-region]instance 1 vlan 1 to 10 13. [SW2-mst-region]instance 2 vlan 11 to 20 14. [SW2-mst-region]active region-configuration 15. SW3：

16. [SW3]stp mode mstp

17. [SW3]stp region-configuration 18. [SW3-mst-region]region-name RG1

19. [SW3-mst-region]instance 1 vlan 1 to 10 20. [SW3-mst-region]instance 2 vlan 11 to 20 21. [SW3-mst-region]active region-configuration 22. SW4：

23. [SW4]stp mode mstp

24. [SW4]stp region-configuration 25. [SW4-mst-region]region-name RG1

26. [SW4-mst-region]instance 1 vlan 1 to 10 27. [SW4-mst-region]instance 2 vlan 11 to 20 28. [SW4-mst-region]active region-configuration

查看mstp实例配置

配置vlan负载

[plain] view plain copy

1. SW1：

2. [SW1]stp instance 1 priority 4096 3. [SW1]stp instance 2 priority 8192 4. 5. SW2：

6. [SW2]stp instance 1 priority 8192 7. [SW2]stp instance 2 priority 4096

查看mstp实例状态信息，SW1为实例1的根桥，SW2为实例2的根桥。
