  address-family ipv4 unicast

   default-route imported //该配置丢失

   import-route static

1、查看控制器上设备网元的数据同步配置为保留增量数据。

2、设备重启时，设备侧会主动断开Openflow连接，然后重新建立Openflow连接；

控制器日志：

1） 设备侧会主动断开Openflow连接

2）重新建立Openflow连接：

3、控制器执行merge操作：

4、查看netconf API手册，确认控制器merge操作就是执行删除 default-route imported 命令操作。

5、重新在Spine设备上增加 default-route imported配置之后，点击审计，该配置是出现在控制器与设备不一致的配置中。

6、目前ADCampus五期B02控制器（E3202P02）上如果选择”保留设备增量数据“，控制器自己下发的配置审计出差异，会平滑掉的。当前BGP vpn里的配置，会被控制器审计出来，显示在“控制器与设备不一致的配置”页签中。

1）将网元的平滑开关关闭：修改网元页面，数据同步选择”默认“或“关闭“。

2）若修改为默认，也需要确认下，全局配置是关闭的状态。
