Description
-----------

Physical interfaces have their state LEDs, software-defined connectivity
does not. This script helps to visualize whether or not an OSPF instance
is running.

Requirements and installation
-----------------------------

Just install the script:

    $ScriptInstallUpdate ospf-to-leds;

... and add a scheduler to run the script periodically:

    /system/scheduler/add interval=20s name=ospf-to-leds on-event="/system/script/run ospf-to-leds;" start-time=startup;

Configuration
-------------

The configuration goes to OSPF instance's comment. To visualize state for
instance `default` via LED `user-led` set this:

    /routing/ospf/instance/set default comment="ospf-to-leds, leds=user-led";
