Abstract:
This document defines version 3 of the Virtual Router Redundancy
Protocol (VRRP) for IPv4 and IPv6. It obsoletes RFC 5798 which
previously specified VRRP (version 3). RFC 5798 obsoleted RFC 3768
which specified VRRP (version 2) for IPv4. 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 Active Router, and it forwards packets sent to
these IPv4 or IPv6 addresses. Active Routers are configured with
virtual IPv4 or IPv6 addresses, and 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.
