1. Introduction
This document introduces a YANG [RFC6020] 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.
1.1. Terminology
The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14, [RFC2119].
The following terms are defined in [RFC6020] and are not redefined
here:
o augment
o data model

2. VRRP YANG model overview
This document defines the YANG module "ietf-vrrp", which has the
following structure:
module: ietf-vrrp
augment /if:interfaces/if:interface/ip:ipv4:
+--rw vrrp
+--rw vrrp-instance* [vrid]
+--rw vrid uint8
+--rw version? enumeration
+--rw log-state-change? boolean
+--rw preempt!
| +--rw hold-time? uint16
+--rw priority? uint8
+--rw accept-mode? boolean
+--rw (advertise-interval-choice)?
| +--:(v2)
| | +--rw advertise-interval-sec? uint8
