通过在实验环境下使用Python程序构造RIP攻击报文，将攻击报文发送给目标路由器进行路由欺骗，致使被攻击路由器学习到错误的路由信息，进而导致被攻击路由器无法实现正常的路由转发功能。在此基础上，通过Python编写抓包嗅探程序分析攻击者所发送的攻击报文，研究其攻击手段和方法，进而采取相应的安全防护措施，增强RIP路由协议的安全性。

This paper constructs RIP attack message by Python program in the experimental environment, and sends the attack mes-sage to the target router for routing deception, which makes the attacked router learn the wrong routing information, and then makesthe attacked router unable to realize the normal routing forwarding function. On this basis, we write packet sniffer program in Py-thon, analyze the attack message sent by the attacker, study its attack means and methods, and then take corresponding security mea-sures to enhance the security of RIP routing protocol.
