The VRRP (Virtual Router Redundancy Protocol) MAC address format is designed to enable the protocol to provide redundancy for routing services. The correct format is represented as 0000.5e00.01xx, where "xx" represents the instance number of the VRRP group, ranging from 01 to 16.

This format emphasizes a structured representation of the MAC address, ensuring that specific bits are dedicated to identifying VRRP functionality. The leading "0000.5e," combined with "00," indicates that this is a registered MAC prefix for multicast addressing. The "01xx" portion is crucial for delineating the different VRRP instances, allowing multiple VRRP groups to exist on the same network segment without a MAC address conflict.

In contrast, the other formats do not appropriately match the designated VRRP format. Options that include colons instead of periods, or those that do not conform to the expected structure, cannot be valid representations of a VRRP MAC address. Thus, the provided format illustrates the precise and regulated manner in which VRRP operates within a networking framework.
