To prevent preemptive behavior in a Virtual Router Redundancy Protocol (VRRP) setup, the correct action involves disabling the preemption functionality on the master router. This is critical because, by default, VRRP allows a router with a higher priority to take over as the master router when it becomes reachable, regardless of whether the current master is still operational.

Disabling preemption is achieved with the appropriate configuration command, which allows the current master router to maintain its role even if a router with a higher priority comes online. Thus, the command that needs to be executed is essential in controlling which router should be regarded as the primary and minimizes unnecessary changes in the routing topology.

The suggestion to use an IP address that is not assigned to a router interface does not contribute to managing preemption behavior. The virtual router might still experience fluctuations in the master due to priority changes if preemption is enabled.

When discussing the option of setting both routers to the same priority value, while this can indeed create a situation where preemption doesn’t occur under normal circumstances, it doesn’t inherently disable preemption behavior; it merely complicates the decision-making process without stopping the potential for one router to reclaim the mastership based on other factors.
