H3C实验报告大全【含18个实验】7-多生成树MSTP

1、多生成树-MSTP目录：一.单域多生成树的配置二.多域生成树的配置一.单域多生成树的配置实验目的：创建多生成树的域创建实例-相当于捆绑在一起的vlan实现负载均衡实验步骤开启STP-创建vlan-配置的MST域-开启trunk链路gaocw1vlan 2 to 30 /创建vlan 2 到30 请等待. 完成.缺省情况下MST 域的三个参数：1. MST 域名为交换机的第一个MAC地址 2. 所有VLAN 均对应到CIST 上，也就是实例03. MSTP 修订级别取值为0注意：1. 要想网络内的实例在同一个MST域，上面的三个参数必须相同！2. 每修改一次MST域，就必须激活一次！gaocw1

2、stp enable /开启生成树协议gaocw1stp region-configuration /进入MST 域视图gaocw1-mst-regionregion-name wang /配置MST域名gaocw1-mst-regioninstance 1 vlan 2 to 10 /配置生成树实例gaocw1-mst-regioninstance 2 vlan 11 to 20gaocw1-mst-regioninstance 3 vlan 21 to 30gaocw1-mst-regionactive region-configuration 此处我没有设置修订值，因为默认修订值都是0，

3、不影响我们设置单域！介绍几个域内的命令check region-configuration ： 本命令用来显示尚未激活的 MST 域的配置信息，revision-level ： 命令用来配置交换机的MSTP 修订级别查看MST与的信息gaocw1display stp region-configuration 操作值： 格式选择符 :0 域名 :wang 修订级别 :0 实例 映射的VLAN 0 1, 31 to 4094 1 2 to 10 2 11 to 203 21 to 30gaocw1int e1/0/2gaocw1-Ethernet1/0/2port link-type trunk

9、 trunk permit vlan all 请等待. 完成.gaocw3int e1/0/6gaocw3-Ethernet1/0/6port link-type trunkgaocw3-Ethernet1/0/6port trunk permit vlan all 请等待. 完成.当我们都设置完后，就可以看一下配置的情况，从sw1看起！gaocw1display stp brief MSTID 端口 角色 STP状态 保护类型 0 Ethernet1/0/2 ROOT FORWARDING NONE 0 Ethernet1/0/6 ALTE DISCARDING NONE 1 Etherne

13、时我们看到的是-sw2是所有实例的跟桥，包括系统自动生成的实例0所以不符合我们所说的负责均衡！ 接下来，实现MSTP的负载均衡功能gaocw1int e1/0/1gaocw1-Ethernet1/0/1stp edged-port enable关闭边界端口属性：stp edged-port disable /配置连接终端设备的端口为域边界端口！gaocw1stp instance 2 root ? primary 主根交换机 secondary 备份根交换机gaocw1stp instance 2 root primary /让sw1为实例二的主根桥，gaocw1stp instance 3

14、root secondary /让sw1为实例三的备份跟桥。gaocw3stp instance 2 root secondary /让sw3为实例二的备份跟桥gaocw3stp instance 3 root primary /让sw1为实例三的主根桥现在查看-就实现了负载分担功能gaocw2display stp brief MSTID 端口 角色 STP状态 保护类型 0 Ethernet1/0/2 DESI FORWARDING NONE 0 Ethernet1/0/4 DESI FORWARDING NONE 1 Ethernet1/0/2 DESI FORWARDING NONE
