基于OSPF路由欺骗的网络监听技术研究

摘要

The network monitoring method on routing spoofing had been studied in detail. The research was important for network security management. First, the network environment was analyzed. The forged link state advertisement message was analyzed. R1 and R2 routers applied Dijkstra algorithm to update their routing table. This article described the method to get the router password.%　　文章研究了基于OSPF路由欺骗的网络监听技术，研究结果对网络安全管理工作有一定意义。文章首先介绍了研究使用的网络环境。详细分析了攻击者伪造的链路状态通告报文。重点研究了R1和R2路由器应用Dijkstra算法更新各自路由表的计算过程。分析了攻击者获取路由器的身份认证信息的方法。
