MSTP_基础实验

            

 

1、交换机创建4个VLAN，分别为：VLAN10、VLAN20、VLAN30、VLAN40

2、MSTP域名为：huawei

3、创建2个实例 instance1 ,instance2

4、VLAN映射：VLAN10、VLAN30映射到instance1 ；VLAN20、VLAN40映射到instance2

5、SW1为instance 1的主根桥，instance 2的备份根桥

6、SW2为instance 2的主根桥，instance 1的备份根桥

 

SW1

#
vlan batch 10 20 30 40
#
stp instance 1 root primary
stp instance 2 root secondary
#
stp region-configuration
 region-name huawei
 revision-level 1
 instance 1 vlan 10 30
 instance 2 vlan 20 40
 active region-configuration
#

 

SW2

#
vlan batch 10 20 30 40
#
stp instance 1 root secondary
stp instance 2 root primary
#
stp region-configuration
 region-name huawei
 revision-level 1
 instance 1 vlan 10 30
 instance 2 vlan 20 40
 active region-configuration
#

 

SW3

#
vlan batch 10 20 30 40
#
stp region-configuration
 region-name huawei
 revision-level 1
 instance 1 vlan 10 30
 instance 2 vlan 20 40
 active region-configuration
#

 

  

 

 

instance 1中端口角色，如下图所示：
