#拓扑结构

生成树的配置概念stp-生成树协议 rstp-快速生成树协议,mstp-多生成树协议根桥:根桥在全网中有且只有一个,其它设备则称为叶子节点。根端口:所谓根端口,是指非根桥设备上离根桥最近的端口。根端口负责与根桥进行通信。非根桥设备上有且只有一个根端口,根桥上没有根端口。MST域:(Multiple Spanning Tree Regions,多生成树域)是由交换网络中的多台设备以及它们之间的网段所构成(域内设备都使能了生成树协议,域名相同,映射关系配置相同)MSTI:一个MST域可以通过MSTP协议生成多颗生成树,各个生成树之间独立并分别与对应的vlan对应

每颗生成树都称为一个MSTI (多生成树实例)

基本配置

1 配置stp模式(默认开启MSTP) 2 配置MST域(使用命令激活或者是全局使能生成树协议才会生效)   进入域视图,配置域名(默认的是mac地址),配置vlan映射表,配置修订级别   激活mst域配置(必选) 3 配置根桥和备份根桥 4 配置设备优先级 5 配置MST域最大跳数 6 配置端口路径开销,配置端口优先级

步骤:

1 交换机上创建vlan,设置trunk口,允许相应的vlan通过2 配置MST域的域名,绑定vlan配置MSTP修订级别3 激活MST域的配置4 配置根桥5 全局开启MSTP协议
