    网络架构:
    192.168.10.1 MikroTik 主路由
    192.168.10.2 OpenWrt DNS 网关

    要求:
    RouterOS的DNS设置为192.168.10.2, 若192.168.10.2 宕机后自动设置更改DNS设置为223.5.5.5

    方法如下:
    Netwatch, 新建一个监控项目
    UP:
    Code:
    :local dns "192.168.10.2"

/ip dns set servers=$dns

/ip dns cache flush

    Down
    Code:
    :local dns "223.5.5.5"

/ip dns set servers=$dns

/ip dns cache flush
