51工具盒子组网需求 {#组网需求}
某大型企业有总部（Hub）和多个分支（Spoke1、Spoke2......，举例中仅使用两个分支），分布在不同地域，总部和分支的子网环境会经常出现变动。分支采用动态地址接入公网。企业现网网络规划使用OSPF路由协议。
现在用户希望能够实现分支之间的VPN互联，同时对总部和分支机构以及分支机构间传输的数据进行加密保护。
配置思路 {#配置思路}
企业网络管理员可以采用如下思路进行分析：
- 由于分支是采用动态地址接入公网的，分支之间互相不知道对方的公网地址，因此必须采用DSVPN来实现分支之间的VPN互联。
- 由于分支数量较多，因此采用shortcut场景的DSVPN。
- 由于分支和总部的子网环境经常出现变动，为简化维护并根据企业网络规划，选择部署OSPF路由协议来实现分支/总部间的通信。
- 由于需要对机构之间的传输数据进行加密保护，因此采用配置IPSec保护的DSVPN来实现该功能。
注意：在DSVPN中部署IPSec时，如果两个分支位于不同NAT设备之后或者总部位于NAT设备之后，则IPSec封装模式仅支持为传输模式。
