【摘要】 针对当前网络工程实验教学的要求和特点,通过比较几种仿真软件的主要特点,将一款能够模拟真实IOS的易用、可视化的GNS3仿真平台应用到网络工程课程实验中,能有效解决理论与实践、教学与实验的问题,增强学生实践能力。笔者着重介绍了利用GNS3搭建Ipsec VPN的实验平台,其搭建和配置方法可以推广到该平台下其它网络工程的实验中。更多还原

【Abstract】 In view of the experiment teaching requirements and characteristics of current network engineering,and comparing the main characteristics of several kinds of simulation software,we can apply a simulation platform with real IOS and visual GNS3 to network engineering course experiment,which can effectively solve the problem of theory and practice,teaching and experiment,and strengthen students’ practical ability.The article hereby introduces how to use GNS3 to set up the IpsecVPN experiment platform,whose method can also be applied to other network engineering experiment.更多还原
