華為實驗

1.實驗拓撲圖：

2.【實驗需求】

使用MSTP實作VLAN10 和VLAN20的互訪，

并且VLAN10的流量通過路徑S3到S1到R1

VLAN20的流量通過路徑S3到S2到R1。

3.實驗步驟：

配置IP位址。

[r1]int g0/0/0

[r1-GigabitEthernet0/0/0]ip add 192.168.10.254 24

[r1-GigabitEthernet0/0/0]undo sh

[r1-GigabitEthernet0/0/0]int g0/0/1

[r1-GigabitEthernet0/0/1]ip add 192.168.20.254 24

[r1-GigabitEthernet0/0/1]undo sh

2.配置VLAN和Trunk。

SW1:

[sw1]vlan batch 10 20

[sw1]int e0/0/2

[sw1-Ethernet0/0/2]port link-type trunk

[sw1-Ethernet0/0/2]port trunk allow- vlan all

[sw1-Ethernet0/0/2]int e0/0/3

[sw1-Ethernet0/0/3]port link-type trunk

[sw1-Ethernet0/0/3]port trunk allow- vlan all

[sw1-Ethernet0/0/3]int e0/0/1

[sw1-Ethernet0/0/1]port link-type hybrid

[sw1-Ethernet0/0/1]port hybrid untagged vlan 10

[sw1-Ethernet0/0/1]port hybrid pvid 10

SW2:

[sw2]vlan batch 10 20

[sw2-Ethernet0/0/2]port link-type trunk

[sw2-Ethernet0/0/2]port trunk allow-pass vlan all

[sw2-Ethernet0/0/2]int e0/0/3

[sw2-Ethernet0/0/3]port link-type trunk

[sw2-Ethernet0/0/3]port trunk allow-pass vlan all

[sw2-Ethernet0/0/3]int e0/0/1

[sw2-Ethernet0/0/1]port link-type hybrid

[sw2-Ethernet0/0/1]port hybrid pvid vlan 20

[sw2-Ethernet0/0/1]port hybrid untagged vlan 20

SW3:

[sw3]int e0/0/1

[sw3-Ethernet0/0/1]port link-type trunk

[sw3-Ethernet0/0/1]port trunk allow-pass vlan all

[sw3-Ethernet0/0/1]int e0/0/2

[sw3-Ethernet0/0/2]port link-type trunk

[sw3-Ethernet0/0/2]port trunk allow-pass vlan all

[sw3-Ethernet0/0/3]int e0/0/3

[sw3-Ethernet0/0/3]port link-type access

[sw3-Ethernet0/0/3]port default vlan 10

[sw3-Ethernet0/0/3]int e0/0/4

[sw3-Ethernet0/0/4]port link-type access

[sw3-Ethernet0/0/4]port default vlan 20

3.配置MSTP。

SW1:

[sw1]stp mode mstp

[sw1]stp region-configuration

[sw1-mst-region]region-name benet.com

[sw1-mst-region]revision-level 1

[sw1-mst-region]instance 1 vlan 10

[sw1-mst-region]instance 2 vlan 20

[sw1-mst-region]active region-configuration

[sw1-mst-region]q

[sw1]stp instance 1 root primary

[sw1]stp instance 2 root secondary

SW2:

[sw2]stp mode mstp

[sw2]stp region-configuration

[sw2-mst-region]region-name benet.com

[sw2-mst-region]revision-level 1

[sw2-mst-region]instance 1 vlan 10

[sw2-mst-region]instance 2 vlan 20

[sw2-mst-region]active region-configuration

[sw2-mst-region]q

[sw2]stp instance 1 root secondary

[sw2]stp instance 2 root primary

SW3:

[sw3]stp mode mstp

[sw3]stp region-configuration

[sw3-mst-region]revision-level 1

[sw3-mst-region]instance 1 vlan 10

[sw3-mst-region]instance 2 vlan 20

[sw3-mst region]active region-configuration

驗證:在SW3 上驗證，display stp b檢視STP接口角色及狀态資訊，其中的instance1中的e0/0/2和instance2中的e0/0/1處于阻塞狀态
