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
