Section 14.1.4
Managing VRRP Trackers
VRRP trackers monitor the state/condition of a route. When the route is unavailable, VRRP will lower its priority or
transition it to a fault state.
NOTE
The decision to increase or decrease the priority of a route must be done in coordination with any
backup VRRP Routers since the priority decides whether a router becomes a Master or a Backup. For
example, if Router X's priority is 150 and Router Y's priority is 145, Router X's priority must be lowered
by 6 to make it a Backup router.
