STP生成树综合配置

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
