MSR系列路由器standby track功能配置

MSR系列路由器

Standby track功能配置

一、       组网：

 

二、       问题描述：

RTA与RTB两台设备以2M链路连接，RTC与RTD之间为卫星链路，在RTD上监控RTA与RTB之间链路，如果发现链路故障切换链路从RTD与RTC走，未发生故障的情况下要求RTC与RTD之间不产生任何流量。

三、过程分析：

1） 全网起OSPF协议，备份链路使用GRE隧道传输私网路由，通过对需求分析，建议在RTD上采用Standby track功能，监控10.0.0.1地址，如果发生异常数据切换到RTC到RTD链路。端口在备份状态下，链路层DOWN，物理层是欺骗状态，不会产生流量。

四、解决方案：
