If a VRRP master router fails, which router is selected as the new master router?

Question

Options

• Arouter with the highest priority
• Brouter with the highest loopback address
• Crouter with the lowest loopback address
• Drouter with the lowest priority

• A
  92% (34)
• C
  5% (2)
• D
  3% (1)

Explanation

VRRP Master Router Election

When a VRRP (Virtual Router Redundancy Protocol) master router fails, the backup router with the highest priority value (ranging from 1–254) takes over as the new master, ensuring seamless gateway redundancy for connected hosts. Priority is the core metric VRRP uses for election, and the router with the default priority of 100 (or a manually configured higher value) wins the role.

Why the distractors are wrong:

• B & C (loopback address): VRRP election does not use loopback addresses as a tiebreaker metric - this is a confusion with other protocols like OSPF DR/BDR election, which uses the highest router ID or loopback.
• D (lowest priority): This is the opposite of the rule; the highest priority wins, not the lowest (again, don't confuse this with protocols like STP, where the lowest bridge priority wins).

Memory Tip: Think of VRRP priority like a job interview - the candidate with the highest score gets the position. If scores tie, the router with the highest IP address on the VRRP interface acts as a tiebreaker.
