摘　　要：VPN技术是路由交换技术课程中的重要内容,以GRE技术与IPSec技术实现VPN为研究对象,通过GNS3软件对4种实现VPN的实验方案进行了仿真和测试。利用Wireshark工具捕获报文,结合路由和报文分析对实验进行了验证,最后给出了实验方案的对比结果。实践表明,利用GNS3构建虚拟实验平台进行实验教学有助于提高实验教学效果,通过实验对比方法增强了学生对VPN技术的理解。VPN technology is an important content in routing and switching technology course.GRE technology and IPSec technology are used to implement VPN,which is chosen as a study object.Four kinds of experimental schemes of VPN are simulated and tested by GNS3 software.The Wireshark tool is used to capture packets.The experiments are verified by combining routing and packet analysis.Finally,the comparison result of the experimental schemes is given in the paper.The practice proves that it helps to improve the experimental teaching effect by using GNS3 to build a virtual experimental platform for experimental teaching,and enhances students'understanding of VPN technology through experimental comparison method.
