I’ve noticed that a useful feature for vrrp is not in the configuration for vrrp notify_fault
there are configuration nodes for notify_master and notify_backup, but if the interface goes into a fault state there’s no notify_fault.
vyos@R2# set high-availability vrrp group group1 transition-script
Possible completions:
backup Script to run on VRRP state transition to backup
fault Script to run on VRRP state transition to fault
master Script to run on VRRP state transition to master
