摘　　要：针对铁路数据通信网一次边界网关协议(BGP)邻居中断告警,基于网管告警、设备软件版本、设备日志等进行故障分析,依据底层错误代码定位故障原因,最终在实验室复现了该故障,并在故障再现时定位了问题路由;分析起源站点(SoO)属性防止BGP路由环路的原理,同时对SoO编号方式提出建议。Starting from a BGP neighbor disconnection alarm of railway data communication network,fault analysis is made using network management alarms,equipment software version and equipment log and the fault cause is determined according to the underlying error code.And the fault is finally reproduced in the laboratory and the trouble route is located when the fault reoccurs.In the end,the principle of using the SoO attribute to prevent BGP routing loop is analyzed and suggestions on SoO numbering mode is also put forward.

关 键 词：数据通信网 边界网关协议 自治系统路径 起源站点 路由环路
