摘　　要：在主、备路由网络架构下,为实时掌握主路由链路和备用路由链路状态,常规网络管理系统利用SNMP协议、ICMP协议,通过获取接口状态和连通性来实现对双出口链路状态的监测。但是,当路由器出口接口外接协议转换器、安全管控设备时,以上两种方式将无法准确监测,存在备份链路中断无告警、主备切换无告警的安全隐患。分析该类型双链路出口链路状态监测的实际需求,提出了一种实现双路由出口链路状态监测的技术方法,并设计和开发了符合需求的告警可视化图例,从而实现对各种类型网络架构下双路由出口链路的监测。In the architecture of primary and backup routing networks,in order to monitor the status of the primary and backup routing links in real time,conventional network management systems use SNMP and ICMP protocols to obtain interface status and connectivity to monitor the status of dual outbound links.However,when the router's outbound interface is connected to an external protocol converter or security control device,these two methods cannot accurately monitor,resulting in security risks such as backup link interruption without alarms and primary/backup switching without alarms.This article analyzes the actual requirements for monitoring the status of dual outbound links,proposes a technical method for implementing dual routing outbound link status monitoring,and designs and develops alarm visualization diagrams that meet the requirements,achieving the monitoring of dual route outbound links under various types of network architectures.
