Which of the following statements about VRRP are true? (Choose three.)
A. VRRP determines the roles of routers (master or backup) in a virtual router based on their priorities.
B. If a backup router works in non-preemption mode and has a higher priority than the masterrouter, it will become the master router unless the master router fails.
C. After a backup router in preemption mode receives a VRRP packet from the master router, it compares its priority with the priority carried in the VRRP packet. If
its priority is higher than the priority of the master router, it preempts to be the master router; if not, it remains in the backup state.
D. If two routers competing for the master router have the same priority, the router with a higher interface IP address becomes the master router.
