Virtual Router Redundancy Protocol
RFC 3768, “Virtual Router Redundancy Protocol”, is a Draft Standard document published in April 2004 by R. Hinden. It obsoletes RFC 2338. It has been obsoleted by RFC 5798 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This memo defines the Virtual Router Redundancy Protocol (VRRP). 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 IP address(es) associated with a virtual router is called the Master, and forwards packets sent to these IP addresses. The election process provides dynamic fail over in the forwarding responsibility should the Master become unavailable. This allows any of the virtual router IP addresses on the LAN to be used as the default first hop router by end-hosts. 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. [STANDARDS-TRACK]
What “Draft Standard” means
A historical maturity level (retired in 2011) that sat between Proposed Standard and Internet Standard and required multiple interoperable implementations.
