| 摘 要： | 以铁路数据网BGP边界网关路由协议和铁路数据网路由规范为基础,研究铁路数据网MPLS BGP VPN双归属业务组网存在的隐患;通过分析论证和网络实践,提出了基于Route-policy与Ip-prefix的路由控制策略优化方案,解决了由于MPLS BGP VPN双归属业务路由控制不合理而将错误的路由信息扩散到全网的问题.

| Abstract: | Based on the BGP border gateway routing protocol and the code for routing of railway data network,the hazards in MPLS BGP VPN dual-homing service of the railway data network are studied.Through analytical demonstration and practice,an optimum solution to routing policy is proposed based on route policy and IP prefix control,solving the problem that railway data network’s MPLS BGP VPN may spread mis-configured routing data to the entire network due to improper control. |
