4.5.3 VRRP
The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides
automatic assignment of available Internet Protocol (IP) routers for participating hosts. The VRRP
router who has the highest number will become the virtual master router. The VRRP router number
ranges from 1 to 255 and usually we use 255 for the highest priority and 100 for backup. If the
current virtual master router receives an announcement from a group member (Router ID) with a
higher priority, then the latter will pre-empt and become the virtual master router.
