STP的简单配置:
拓扑见QQ收藏
实验要求:
1、S1为VLAN 11、13的根,VLAN12、14的备份根;
2、S2为VLAN 12、14的根,VLAN11、13的备份根;
3、开启stp安全保护功能:
(1)S3连接用户终端接口配置为边缘端口,不转发BPDU
(2)开启根保护
(3)开启防TC-BPDU攻击保护功能
(4)开启环路保护功能
特别注意:有可能需要在接口开启 stp enable 功能,也可能是在全局,模拟器全局不支持

配置接口为边缘端口,不发送BPDU:
[S3]int g1/0/3
[S3-GigabitEthernet1/0/3]stp edged-port

[S3-GigabitEthernet1/0/6]stp edged-port
[S3-GigabitEthernet1/0/6]quit
注意:一般配置的都是access端口
开启根保护:
在所有交换机的根端口,备份端口,制定端口上配置
[S1]int g1/0/1
[S1-GigabitEthernet1/0/1]stp root-protection
[S1-GigabitEthernet1/0/1]int g1/0/2
[S1-GigabitEthernet1/0/2]stp root-protection
开启防TC-BPDU攻击保护功能:
[S1]stp tc-protection
[S1]stp tc-protection threshold 5
注意:当收到TC-BPDU后立即进行地址表项刷新操作的次数最多为5.默认为6.(所有交换机配置)
开启环路保护功能:
[S3]int g1/0/1
[S3-GigabitEthernet1/0/1]stp loop-protection
[S3-GigabitEthernet1/0/1]int g1/0/2
[S3-GigabitEthernet1/0/2]stp loop-protection
注意:只在非根交换机的所有处于环路的接口下操作
