Abstract:
This document defines version 3 of the Virtual Router Redundancy
Protocol (VRRP) for IPv4 and IPv6. It is based on VRRP (version 2)
for IPv4 that is defined in RFC 3768 and in "Virtual Router
Redundancy Protocol for IPv6", and obsoletes the prevision
specification of this version documented in RFC 5798. 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 independent of one
another and always treated as separate virtual router instances. 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.
