MSTP实验

一、实验拓扑

二、实验要求

三、实验步骤

1、创建vlan

2、创建端口组，放通vlan

3、配置MSTP

4、配置主备奋根

一、实验拓扑

二、实验要求

1、所有交换机上创建vlan10，vlan20，vlan30和vlan40
2、所有交换机之间的端口配置为Trunk，并放行相关vlan
3、按照图示分区配置MSTP，并配置主备根网桥

三、实验步骤

1、创建vlan

[SW1]vlan batch 10 20 30 40
[SW2]vlan batch 10 20 30 40
[SW3]vlan batch 10 20 30 40
[SW4]vlan batch 10 20 30 40
[SW5]vlan batch 10 20 30 40
[SW6]vlan batch 10 20 30 40
[SW7]vlan batch 10 20 30 40

2、创建端口组，放通vlan

[SW1]port-group group-member g0/0/1 to g0/0/2
[SW1-port-group]port link-type trunk
[SW1-port-group]port trunk allow-pass vlan 10 20 30 40[SW2]port-group group-member g0/0/1 to g0/0/2
[SW2-port-group]port link-type trunk
[SW2-port-group]port trunk allow-pass vlan 10 20 30 40[SW3]port-group group-member g0/0/1 to g0/0/4
[SW3-port-group]port link-type trunk
[SW3-port-group]port trunk allow-pass vlan 10 20 30 40[SW4]port-group group-member g0/0/1 to g0/0/3
[SW4-port-group]port link-type trunk
[SW4-port-group]port trunk allow-pass vlan 10 20 30 40[SW5]port-group group-member g0/0/1 to g0/0/2
[SW5-port-group]port link-type trunk
[SW5-port-group]port trunk allow-pass vlan 10 20 30 40[SW6]port-group group-member g0/0/1 to g0/0/3
[SW6-port-group]port link-type trunk
[SW6-port-group]port trunk allow-pass vlan 10 20 30 40[SW7]port-group group-member g0/0/1 to g0/0/2
[SW7-port-group]port link-type trunk
[SW7-port-group]port trunk allow-pass vlan 10 20 30 40

3、配置MSTP

[SW1]stp enable 
[SW1]stp mode mstp 
[SW1]stp region-configuration 
[SW1-mst-region]region-name hw1
[SW1-mst-region]revision-level ?INTEGER<0-65535>  Revision level[SW1-mst-region]revision-level 1
[SW1-mst-region]instance ?INTEGER<0-48>  Identifier of spanning tree instance[SW1-mst-region]instance 1 vlan 10 20
[SW1-mst-region]instance 2 vlan 30 40
[SW1-mst-region]active region-configuration # 一定要加上！！！，否则配置不生效

[SW2]stp enable 
[SW2]stp mode mstp 
[SW2]stp region-configuration 
[SW2-mst-region]region-name hw1
[SW2-mst-region]revision-level 1
[SW2-mst-region]instance 1 vlan 10 20
[SW2-mst-region]instance 2 vlan 30 40
[SW2-mst-region]active region-configuration[SW3]stp enable 
[SW3]stp mode mstp 
[SW3]stp region-configuration 
[SW3-mst-region]region-name hw1
[SW3-mst-region]revision-level 1
[SW3-mst-region]instance 1 vlan 10 20
[SW3-mst-region]instance 2 vlan 30 40
[SW3-mst-region]active region-configuration[SW4]stp enable 
[SW4]stp mode mstp 
[SW4]stp region-configuration 
[SW4-mst-region]region-name hw2
[SW4-mst-region]revision-level 2
[SW4-mst-region]instance 1 vlan 10
[SW4-mst-region]instance 2 vlan 30
[SW4-mst-region]active region-configuration[SW5]stp enable 
[SW5]stp mode mstp 
[SW5]stp region-configuration 
[SW5-mst-region]region-name hw2
[SW5-mst-region]revision-level 2
[SW5-mst-region]instance 1 vlan 10
[SW5-mst-region]instance 2 vlan 30
[SW5-mst-region]active region-configuration [SW6]stp enable 
[SW6]stp mode mstp 
[SW6]stp region-configuration 
[SW6-mst-region]region-name hw2
[SW6-mst-region]revision-level 2
[SW6-mst-region]instance 1 vlan 10
[SW6-mst-region]instance 2 vlan 30
[SW6-mst-region]active region-configuration [SW7]stp enable 
[SW7]stp mode mstp 
[SW7]stp region-configuration 
[SW7-mst-region]region-name hw3
[SW7-mst-region]revision-level 3
[SW7-mst-region]instance 1 vlan 20
[SW7-mst-region]instance 2 vlan 40	
[SW7-mst-region]active region-configuration

4、配置主备奋根

[SW1]stp instance 1 ?priority  Specify bridge priorityroot      Specify root switch[SW1]stp instance 1 root primary
[SW1]stp instance 2 root secondary [SW2]stp instance 1 root secondary
[SW2]stp instance 2 root primary [SW4]stp instance 1 root primary 
[SW4]stp instance 2 root secondary [SW6]stp instance 1 root secondary 
[SW6]stp instance 2 root primary
