摘　　要：随着信息技术在各个领域的不断普及,原有的IPv4协议已经不足以满足人们的所需,IP地址空间的不足、路由表的急速增长等问题一一暴露。IPv6协议应运而生。IPv6协议解决了IPv4协议的各种不足,它拥有更大的地址空间;更小的路由表;更高的安全性;更好的头部格式;加入了对自动配置的支持等优秀特性。随着高校的不断扩招,也使得校园网用户急剧增长,为了满足校园网的实用性,安全性等问题,文章基于IPv4协议与IPv6网络协议共存的情况下,利用隧道技术将IPv6封装进IPv4网络中,再通过BGP协议进行宣告重分发各模块的信息以实现全网互通的目的。With the continuous popularization of information technology in various fields,the original IPv4 protocol cannot meet people's needs.The lack of IP address space,the rapid growth of routing table and other problems are exposed one by one.Therefore,IPv6 protocol was born,which solves all kinds of shortcomings of IPv4 protocol.It bas more address space,smaller routing table,higher security,better header format,automatic configuration support and other excellent features.In order to meet the practicability,security and other issues of campus network,based on the coexistence of IPv4 protocol and IPv6 network protocol,this paper uses BGP and other protocols to build a small campus communication network,divides the whole network into four modules,and encapsulates IPv6 into IPv4 network by using tunnel technology.And the BGP protocol is used to announce and redistribute the information of each module to achieve the purpose of network interoperability.
