Run this in schedulers that fire on startup without interval. Schedulers
should look something like this:
/ system scheduler {
add name=global-scripts on-event="/ system script { run global-config; run global-config-overlay; run global-functions; }" start-time=startup;
add name=bridge-port-to-default on-event="/ system script { run global-wait; run bridge-port-to-default; }" start-time=startup;
}
