Purpose

To enable and configure the Virtual Router Redundancy Protocol (VRRP). This protocol
eliminates the single point of failure inherent in the static default routed environment by
transferring the responsibility from one router to another if the original router goes down. VRRP‐
enabled routers decide who will become master and who will become backup in the event the
master fails.
