What is VRID?

• A. Virtual Router ID - UUID for the pair of HA devices on the subnet
• B. Virtual Routing Interface Descriptor
• C. Value Router ID
• D. Virtual Relay ID

Answer: (A)

VRID is the Virtual Router ID, the numeric identifier used by VRRP to identify the single virtual router that an HA pair presents on a subnet. In a high-availability setup, one device acts as the master for that virtual router and answers traffic for the virtual IP; if it fails, the standby takes over. The VRID ties the two devices to the same virtual router instance on that subnet, enabling seamless failover and continuity for clients.
