VPN技术在局域网中的应用 李洋龙 摘要 随着网络应用在现实企业工作环境中地位的不断上升，也鉴于各企业对网络环境更高的标准和更复杂的需求，传统的网络解决方案已经不足以满足人们对廉价与安全的双重标准，于是，VPN（Virtual Private Network）即虚拟专用网络应运而生。 在此，我将浅谈VPN技术的具体应用，并通过实验过程展现VPN的一些优势，即在不租用互联网服务提供商（ISP）的数字数据网（DDN）专线的情况下，通过它是如何实现不互联的两(多)个局域网间实现安全通信甚至是通过ISP传递各自私网路由信息的。 由于昂贵的设备费用问题以及没有可用的企业网络环境，笔者将会通过GNS 3 模拟器加载Cisco路由器3640的IOS来模拟企业局域网和中间互联网服务提供商的设备以实现相关的实验操作过程，我们将会在完成整个配置后通过debug或show等命令来验证实验结果是否符合我们的期望。 关键词：虚拟专用网络；多协议标签交换；Internet 协议安全性 VPN technology in the LAN Li Yanglong Abstract With the rising status of network applications in the real business environment, also in view of the higher environmental standards and more complex network needs of enterprises, the traditional network solutions have been insufficient to meet peoples double standards on the cheap and safe, so, VPN (Virtual Private Network) came into being. Here, I will discuss the specific application of VPN technology, and show some advantages of VPN through the experimental process. Namely under the condition of not renting digital data network (DDN) special line of the Internet service provider (ISP)，how to achieve secure communications by no interconnection between the two (and more) LANs , and even to pass their respective network routing information through your ISP. Due to the expensive equipment costs and the lack of available enterprise network environment, I will simulate the enterprise LAN and Internet service providers among devices loaded Cisco router IOS 3640 by GNS 3 simulator, in order to achieve process-related experimental operation. We will be in the completion of the entire configuration, through the debug or show commands to verify whether the results accord with our expectations.
