1.  Introduction

   This document introduces a YANG [RFC6020][RFC7950] data model for
   Virtual Router Redundancy Protocol (VRRP) [RFC3768][RFC5798].  VRRP
   provides higher resiliency by specifying an election protocol that
   dynamically assigns responsibility for a virtual router to one of the
   VRRP routers on a LAN.

   This YANG model supports both version 2 and version 3 of VRRP.  VRRP
   version 2 defined in [RFC3768] supports IPv4.  VRRP version 3 defined
   in [RFC5798] supports both IPv4 and IPv6.
