1.要求：
（1）总部实现高可靠性设计，接入层断掉一根线或汇聚、核心设备故障都不能影响数据正常转发
（2）分部1人数较少，采用单臂路由互通
（3）总部、分部1、2之间都能访问互联网
（4）外网能够访问总部的HTTP server 和FTP server
（5）总部和两个分部之间通过DSVPN实现内网互通
2.总部配置
（1）创建vlan并加入接口，将核心交换机之间链路捆绑为e-trunk，确保任何一台故障时另一台能正常转发数据

[LSW9-Eth-Trunk1]port link-type trunk
[LSW9-Eth-Trunk1]port trunk allow-pass vlan 16 100 101
2）配置MSTP（要求vlan 100的根桥为LSW8，vlan 101的根桥为LSW9）
[LSW10]stp region-configuration
[LSW10-mst-region]region-name DMZ1
[LSW10-mst-region]revision-level 1

[LSW10-GigabitEther***0/0/3]int g0/0/4
[LSW10-GigabitEther***0/0/4]stp edged-port enable
3）配置VLAN间路由
[LSW8]int Vlanif 15
[LSW8-Vlanif15]ip add 192.168.15.1 24
[LSW8]int Vlanif 100
[LSW8-Vlanif100]ip add 10.1.100.1 24
