STP生成树综合配置

1.创建vlan10 20 30 40 pc相连端口设置access 加入vlan10 20 不参与生成树选举 禁用stp生成树
把3 ，4端口加入trunk 同意通过所有vlan
SW1 stp enable
sw1 stp mode mstp

  • sw2和1相同设置
    2.sw3创建vlan10 20 30 40 把三个端口全部设置trunk 同意通过所有的vlan e0/0/3设置禁用stp
    3.r1 进入g0/0/0.1 0.2 0.3 0.4
    dot1q termination vid 10 //子接口加入vlan编号
    ip address 192.168.10.1 24 //设置ip地址
    arp broadcast enable //打开ARP广播
    打开g0/0/1设置ip
    r2设定接口ip 设定为默认路由0.0.0.0 0.0.0.0 100.1.1.1
    4.交换机设置mstp模式
    5.配置生成树区域，设置区域名称，允许vlan10 20 通过
    [sw1]stp enable
    [sw1]stp mode mstp
    [sw1]stp region-configuration
    [sw1-mst-region]region-name test
    [sw1-mst-region]instance 1 vlan 10 20
    [sw1-mst-region]instance 2 vlan 30 40
    [sw1-mst-region]active region-configuration //激活stp区域
    6.指定每个区域根网桥 instance 1 :sw1 instance 2 :sw2
    [sw1]stp instance 1 priority 4096
    [sw1]stp instance 2 priority 8192

[sw2]stp instance 1 priority 8192
[sw2]stp instance 2 priority 4096
