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