Title : Virtual Router Redundancy Protocol Version 3 for IPv4 and IPv6
Author(s) : S. Nadas
Filename : draft-nadas-vrrp-unified-spec-00.txt
Pages : 43

This memo 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 on
draft-ieft-vrrp-ipv6-spec-08.txt. 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 Master, and forwards packets sent to these IPv4 or IPv6
addresses. VRRP Master routers are configured with virtual IPv4 or
IPv6 addresses and VRRP Backup routers infer the address family of
the virtual addresses being carried based on the transport protocol.
IPv4 addresses and IPv6 addresses never belong to the same group,
that is, each address family has its own set of VRRP groups. The
election process provides dynamic fail over in the forwarding
responsibility should the Master 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 switch over to back up
routers than can be obtained with standard IPv6 Neighbor Discover
(RFC 2461) mechanisms.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
