Visualize OSPF state via LEDs
=============================
[◀ Go back to main README](../README.md)
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";
