1  简介

本文档介绍使用TRACK和NQA联动对链路状态检测并做出相应处理的典型配置。

2  配置前提

本文档不严格与具体软、硬件版本对应，如果使用过程中与产品实际情况有差异，请参考相关产品手册，或以设备实际情况为准。

本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。

本文档假设您已了解接口备份、TRACK和NQA特性。

3  配置举例

3.1  组网需求

如图1，Server A所在网络部署了四台设备，路由器之间起OSPF协议.在正常情况下，由ServerB和ServerA通信通过路由器AB之间的链路；当路由器A和B之间链路接口出现故障时，数据通过隧道Tunnel1转发；当A和B之间链路接口故障恢复后，数据通过路由器AB之间链路转发。

图1 Track配置组网图

3.2  配置思路

·     为了让全网互通，各路由器上启用OSPF协议；

·     在Router C上采用Standby track功能，配置NQA监控12.12.12.1地址，如果发生异常数据切换到Router C到Router D链路。

3.3  使用版本

本举例是在Release 2317版本上进行配置和验证的。

3.4  配置注意事项

·     在RouterC与RouterD之间配置静态路由将流量引到隧道上；

·     NQA与Track的联动关联要匹配。

3.5  配置步骤

3.5.1  Router A的配置
