Abstract:
   This document defines the Virtual Router Redundancy Protocol (VRRP)
   for IPv4 and IPv6.  It is version three (3) of the protocol, and it
   is based on VRRP (version 2) for IPv4 that is defined in RFC 3768 and
   in "Virtual Router Redundancy Protocol for IPv6".  VRRP specifies an
   election protocol that dynamically assigns responsibility for a
   virtual router to one of the VRRP routers on a LAN.  The VRRP router
   controlling the IPv4 or IPv6 address(es) associated with a virtual
   router is called the VRRP Active Router, and it forwards packets sent
   to these IPv4 or IPv6 addresses.  VRRP Active Routers are configured
   with virtual IPv4 or IPv6 addresses, and VRRP Backup Routers infer
   the address family of the virtual addresses being advertised based on
   the IP protocol version.  Within a VRRP router, the virtual routers
   in each of the IPv4 and IPv6 address families are a domain unto
   themselves and do not overlap.  The election process provides dynamic
   failover in the forwarding responsibility should the Active Router
   become unavailable.  For IPv4, the advantage gained from using VRRP
   is a higher-availability default path without requiring configuration
   of dynamic routing or router discovery protocols on every end-host.
   For IPv6, the advantage gained from using VRRP for IPv6 is a quicker
   switchover to Backup Routers than can be obtained with standard IPv6
   Neighbor Discovery mechanisms.

   The VRRP terminology has been updated conform to inclusive language
   guidelines for IETF technologies.  The IETF has designated National
   Institute of Standards and Technology (NIST) "Guidance for NIST Staff
   on Using Inclusive Language in Documentary Standards" for its
   inclusive language guidelines.  This document obsoletes VRRP Version
   3 [RFC5798].
