Ah, that's hold-time for preemption. When a former vrrp master router
rejoins the network after a reboot, for example, if preemption is
enabled (default) then it immediately takes over, regardless of it's IGP
or BGP state. With preemption hold-time you can tell the restarting
router to wait a couple of minutes to let IGP & BGP stabilize before it
preempts the current vrrp router.
This has nothing to do with the actual normal vrrp operation and does
not affect failover times for vrrp.
Kind regards,
Felix
