摘　　要：RIP协议属于内部网关路由协议,有RIPv1、RIPv2两个版本,通常用于小型自治系统内交换路由信息。本文在对RIP报文格式、产生路由环路的原因以及防环机制进行深入研究的基础上,利用EVE-NG网络模拟器设计了计数无穷大、水平分割、毒性逆转等防环机制仿真实验。通过分析debug ip rip命令输出的路由更新信息并对照路由表的变化,直观地展现了上述防环机制的工作过程,同时验证了其有效性。本文研究结果可为读者在实际网络中部署RIP协议提供重要参考。RIP is an internal gateway routing protocol,which has two versions,RIPv1 and RIPv2.It is often used to exchange routing information in a small autonomous system.Based on the in-depth study of RIP message format,the cause of routing loop and anti loop mechanism,the simulation experiments of anti loop mechanism such as infinite count,horizontal segmentation,toxicity reversal are designed and implemented by EVE-NG network simulator.Combined with the analysis of debug IP rip command and rip routing table,the working process and effectiveness of the above-mentioned anti ring mechanism are verified.It can provide important reference for readers to deploy RIP protocol in actual network.
