多区域分布式网络互连的设计与实现

The Design and Implementation of a Multi-area Distribution Network Interconnection

为解决某大型企业跨Internet的内部网络互连问题,本文在基于IPSec保证数据安全传输的基础上,为该企业提出了点到点的GRE隧道、DMVPN、DVPN三种解决方案及实现方法,可使其所使用的动态路由协议OSPF跨Internet安全地传输,并分析了这三种方案各自的优缺点及适用场合。

In order to solve the problem of a large enterprise internal network interconnection across the Internet, the paper puts forward such solutions as GRE tunnel from point to point, DMVPN, DVPN based on IPSec secure data transmission,which make the dynamic routing protocol OSPF safely transmitted across the In-ternet. It also analyzes their respective advantages and disadvantages and their applicable occasions.
