多生成树协议MSTP的配置
实验六：多生成树协议MSTP 的配置
实验目的
了解并掌握多生成树协议的配置 背景描述
某企业网络管理员认识到，传统的生成树协议(STP)是基于整个交换网络产生一个树形拓扑结构，所
有的VLANs 都共享一个生成树，这种结构不能进行网络流量的负载均衡，使得有些交换设备比较繁忙，而另一些交换设备又很空闲，为了克服这个问题，他决定采用基于VLAN 的多生成树协议MSTP ，现要在交换机上做适当配置来完成这一任务。

实验步骤
1.交换机Switch1的一些相应配置
(1)创建Vlan10和Vlan20
Switch1(config)#vlan 10
Switch1(config-vlan)#exit
Switch1(config)#vlan 20
Switch1(config-vlan)#exit
(2)设置Trunk口和端口fa0/1与fa0/2的聚合
Switch1(config)#inter range fa 0/1-2
Switch1(config-if-range)#switchport mode trunk
Switch1(config-if-range)#exit
Switch1(config)#inter range fa 0/1-2
Switch1(config-if-range)#port-group 1
Switch1(config-if-range)#exit ！设置端口fa0/1-2为trunk并端口聚合
Switch1(config)#inter range fa 0/3-4
Switch1(config-if-range)#switchport mode trunk
Switch1(config-if-range)#exit
(3)开启生成树协议设为MSTP模式，并作相应设置
Switch1(config)#spanning-tree！开启生成树
Switch1(config)#spanning-tree mode mstp！配置生成树模式为MSTP
Switch1(config)#spanning-tree mst configuration! 进入MSTP配置模式
Switch1(config-mst)#name taishan！配置域名称
Switch1(config-mst)#revision 1！配置版本（修订号）
Switch1(config-mst)#instance 1 vlan 10！配置instance 1（实例1）并关联Vlan 10 Switch1(config-mst)#instance 2 vlan 20！配置instance 2（实例2）并关联Vlan 20 Switch1(config-mst)#exit
Switch1(config)#spanning-tree mst 1 priority 8192
！提升交换机Switch1在实例1上的优先级,缺省是32768，值越小越优先成为该instance 中的root switch,这一配置能确定Switch1为instance的根桥
Switch1(config)#end
【注意事项】
l 对规模很大的交换网络可以划分多个域（region），在每个域里可以创建多个instance（实例）；
2 划分在同一个域里的各台交换机须配置相同的域名（name）、相同的修订号（revision number）、相同的instance—vlan 对应表；
3 交换机可以支持65个MSTP instance，其中实例0是缺省实例，是强制存在的，其它实例可以创建和删除；
4 将整个spanning-tree恢复为缺省状态用命令spanning-tree reset 。
5 注意各个交换机的查看（验证）配置信息应该在所有的交换机配置完成后进行。
