Technical Summary
 This document describes a YANG data model for Virtual Router Redundancy (VRRP), and both version 2 and 3 are covered.
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. The protocol has been implemented and deployed by most of network equipment vendors.  Providing a standard YANG model will facilitate the protocol configuration and status in a vendor independent way.
