VRRP
The Virtual Router Redundancy protocol is designed to handle default router failures by
providing a scheme to dynamically elect a backup router. The driving force was to minimize
“black hole” periods due to the failure of the default gateway router during which all traffic
directed towards it is lost until the failure is detected. Though static configuration of default
routes is popular, such an approach is susceptible to a single point of failure when the default
router fails. VRRP advocates the concept of a “virtual router” associated with one or more IP
Addresses that serve as default gateways. In the event that the VRRP Router controlling
these IP Addresses (formally known as the Master) fails, the group of IP Addresses and the
default forwarding role is taken over by a Backup VRRP Router.
