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].
