SR8808 nqa不生效

路由器（1.1.1.1）---（ospf）---传输设备------（1.1.1.2）交换机

手动断掉nqa探测地址的接口，看track一直是Positive状态，同时也没有down掉 FortyGigE1/1/5  这个接口

track的状态也是Positive，未改变

-----------display track all---------

Track ID: 1

    Interface: --

断掉交换机x.x.1.2所在接口时，发现路由器pingx.x.1.2还是能通

因为通过OSPF学到了此路由，但是下一跳地址改变了，所以nqa entry admin NQA就无法匹配了

在track没联动成功时查看NQA信息，发现一直有内部报错计数增加

内部报错，不在Over-threshold Num值里体现，所以这里的探测失败次数显示为0。

将  next-hop ip ，改为out interface 配置探测报文出接口

且当因内部错误探测失败，无法联动track项切换
