摘　　要：在分析ISATAP隧道技术原理和IPv6地址格式的基础上,基于Dynamips仿真平台部署了一个企业IPv4/IPv6网络,设计了拓扑图和IP地址分配表,解析了主要配置命令,验证了网络的连通性.通过查看路由表信息,明确了ISATAP协议构造IPv6全局单播地址的方法;通过数据包收发率和网络吞吐量,说明网络具有收敛时间快且抖动较为平滑的特性,为ISATAP隧道技术的应用提供了参考依据.In the tunneling technology of IPv4 to IPv6, ISATAP has the advantages of easy deployment, easy combination with other transition technology, absence of public IPv4 address, and easy realization. Based on the analysis of the principle of ISATAP tunnel technology and the format of IPv6 address, an en-teiprise IPv4/lPv6 network is deployed on the basis of the Dynamips simulation platform. The topology and IP address allocation table are designed, the main configuration commands are parsed and the connectivity of the network is verified. By looking at the routing table information, the method of constructing the IPv6 global unicast address by ISATAP protocol is defined. Through the packet delivery rate and network throughput, it is shown that the network has the characteristics of fast convergence time and smooth jitter. These provide reference for the application of ISATAP tunneling technology.
