华为eNSP配置MSTP多实例实验

1、一、搭建本次实验的拓扑结构

四台交换机，连接成环形结构

2、二、配置所有交换机的VLAN

[S1]vlan batch 3 to 8 [S2]vlan batch 3 to 8 [S3]vlan batch 3 to 8 [S4]vlan batch 3 to 8

3、三、配置本次实验的链路接口信息

[SW1-GigabitEthernet0/0/1]dis th#interface GigabitEthernet0/0/1 port link-type trunk port trunk allow-pass vlan 2 to 4094#

[SW1-GigabitEthernet0/0/1]int e0/0/13[SW1-Ethernet0/0/13]dis thinterface Ethernet0/0/13 port link-type trunk port trunk allow-pass vlan 2 to 4094#

[SW3-GigabitEthernet0/0/10]port link-type trunk [SW3-GigabitEthernet0/0/10]port trunk allow-pass vlan all [SW3-GigabitEthernet0/0/10]bpdu enable

[SW4-GigabitEthernet0/0/10]port link-type trunk [SW4-GigabitEthernet0/0/10]port trunk allow-pass vlan all [SW4-GigabitEthernet0/0/10]bpdu enable

4、四、配置基本区域和两个实例

配置交换机属于同一个区域RG1，实例1与VLAN3、4、5建立映射关系，实例2与VLAN6、7、8建立映射关系，激活域配置

SW3：

stp region-configuration region-name RG1 revision-level 1 instance 1 vlan 3 to 5 instance 2 vlan 6 to 8 active region-configuration

[SW4-mst-region]dis th#stp region-configuration region-name 1 revision-level 1 instance 1 vlan 3 to 5 instance 2 vlan 6 to 8 active region-configuration#

[SW1-mst-region]dis th#stp region-configuration region-name RG1 revision-level 1 instance 1 vlan 3 to 5 instance 2 vlan 6 to 8 active region-configuration

[SW2-mst-region]dis th #stp region-configuration region-name RG1 revision-level 1 instance 1 vlan 3 to 5 instance 2 vlan 6 to 8 active region-configuration#

5、五、配置上述的条件后查看当前所有交换机的MSTP信息

[SW2]dis stp bri MSTID  Port                        Role  STP State     Protection   0    Ethernet0/0/13              ALTE  DISCARDING      NONE   0    GigabitEthernet0/0/1        ROOT  FORWARDING      NONE   1    Ethernet0/0/13              ROOT  FORWARDING      NONE   1    GigabitEthernet0/0/1        DESI  FORWARDING      NONE   2    Ethernet0/0/13              ROOT  FORWARDING      NONE   2    GigabitEthernet0/0/1        DESI  FORWARDING      NONE

[SW1]dis stp bri MSTID  Port                        Role  STP State     Protection   0    Ethernet0/0/13              ALTE  DISCARDING      NONE   0    GigabitEthernet0/0/1        DESI  FORWARDING      NONE   0    GigabitEthernet0/0/2        ROOT  FORWARDING      NONE   1    Ethernet0/0/13              ROOT  FORWARDING      NONE   1    GigabitEthernet0/0/1        ALTE  DISCARDING      NONE   2    Ethernet0/0/13              ROOT  FORWARDING      NONE   2    GigabitEthernet0/0/1        ALTE  DISCARDING      NONE

6、六、配置实例的优先级

[SW4]stp instance 2 priority 0 [SW3]stp instance 2 priority 4096 [SW2]stp instance 2 priority 8192

7、七、配置完实例的优先级后再查看MSTP信息

[SW4]dis stp bri MSTID  Port                        Role  STP State     Protection   0    GigabitEthernet0/0/2        DESI  FORWARDING      NONE   0    GigabitEthernet0/0/9        DESI  FORWARDING      NONE   0    GigabitEthernet0/0/10       DESI  FORWARDING      NONE   0    GigabitEthernet0/0/13       DESI  FORWARDING      NONE   1    GigabitEthernet0/0/10       DESI  FORWARDING      NONE   1    GigabitEthernet0/0/13       DESI  FORWARDING      NONE   2    GigabitEthernet0/0/10       DESI  FORWARDING      NONE   2    GigabitEthernet0/0/13       DESI  FORWARDING      NONE
