What are the possible values for priority in VRRP?

In the Virtual Router Redundancy Protocol (VRRP), the priority value is crucial for determining which router will take on the role of the master router. The valid range for the priority value is from 1 to 254. This range ensures that each router participating in the VRRP group can have a unique priority level, which influences the election process if multiple routers are configured with VRRP.

A priority value of 255 is reserved in VRRP and is used to indicate a non-operational state for the router, meaning that it will not participate in the master election. Therefore, the range from 1 to 254 provides sufficient granularity for router priority without including values that do not serve an operational role in the protocol, such as zero or 255. This distinction is important for ensuring that the redundancy and failover capabilities provided by VRRP function correctly.
