Redundant Connection Script for MikroTik

Redundant connection Mikrotik howto

This is a scenario where we have two independent ISP connections coming into Routerboard. Let's say the ISP1 is the major one, we use everyday, then the ISP2 is the backup solution, it should be used only when the ISP1 is down.
This script will do the job automatically:

:if ([/interface pppoe-client find name="ISP1"] =  [/interface pppoe-client find name="NETIA" running=no]) do={/interface pppoe-client set [/interface pppoe-client find name="ISP2"] disable=no}
