In VRRP, what factor does not contribute to the selection of the master router?

In VRRP (Virtual Router Redundancy Protocol), the selection of the master router is determined by specific criteria, and among these, the ability to respond to ARP requests does not play a role in this selection process. Instead, the factors that influence the master router election include the priority value set in the configuration, the presence of the no-preempt option, and the IP address of the router.

The priority value is a key determining factor; routers configured with a higher priority will take precedence in the election process. If there are routers with the same priority, the one with the numerically highest IP address becomes the master. The no-preempt option affects whether a higher-priority router can reclaim the master role once it comes back online; without it, a router with a higher priority will take over if it becomes available.

Responding to ARP requests is related to the operation of the protocol but is not a factor in determining which router becomes the master. The selection and election process relies on the pre-defined configurations and priorities rather than the operational responsiveness of the routers in terms of ARP.
