[精华]mstp单区域多实例生成树

实验：MSTP单区域多实例生成树

————T38班李义1.实验拓扑图：

2.实验目标：

（1）熟悉CISCO设备的基本调试命令和常用配置命令（2）掌握单区域多实例的配置并查看相关信息

3．实验步骤

（1）基本信息配置

（2）接口信息配置

（3）单区域多实例生成树配置

(4) 实验结果

4．实验环境：

实验室真实设备环境。

5.实验的详细配置：

（1）基本信息配置

S1的基本信息配置：

长焰煤

enable

conf

hostname S1

体内藏毒

no ip domain-lookup

line console 0

loggi syn

no login

privi le 15

line vty 0 4

no login

privi le 15

S2、S3的基本信息配置同S1（略）。

(2）接口信息配置：

S1的接口信息配置：

vtp mode tran

vlan 1-4

exit

inter fa 0/2

sw mo trunk

sw tru en do

sw tru all vlan all

exit

inter fa 0/1

sw mo trunk

sw tr en do

sw tru all vlan all

S2接口信息配置：

vtp mode tran

vlan 1-4

exit

inter fa 0/1

sw mo trunk

sw tru en do

sw tru all vlan all

exit

inter fa 0/2

sw mo trunk

sw tr en do

sw tru all vlan all

S3接口信息配置：

inter fa 0/1

sw mo trunk

sw tru all vlan all

exit

inter fa 0/2

sw mo trunk

sw tru all vlan all

（3）单区域多实例生成树配置S1的多实例生成树配置：span mst confi

name bf

revis 1

instan 1 vlan 1,2

instan 2 vlan 3,4

exit

span mst 0 pri 0

span mst 1 pri 4096

span mst 2 pri 8192

span mode mst

S2的多实例生成树配置：

span mst confi

name bf

revis 1

instan 1 vlan 1,2

instan 2 vlan 3,4

exit

span mst 0 pri 4096

span mst 1 pri 8192

她是我的朋友教学设计

span mst 2 pri 4096

span mode mst

S3的多实例生成树配置：

span mst confi

name bf

revis 1

instan 1 vlan 1,2

instan 2 vlan 3,4

exit

span mode mst

（4）实验结果：

S1的实验结果：

S1#show spanning-tree mst

># MST00 vlans mapped: 5-4094

Bridge address 000d.bd25.3200 priority 0 (0 sysid 0) Root this switch for CST and IST
