                   draft-ietf-rtgwg-arp-yang-model-00

Abstract

   This document defines a YANG data model to describe Address
   Resolution Protocol (ARP) configurations.  The data model performs as
   a guideline for configuring ARP capabilities on a system.  It is
   intended this model be used by service providers who manipulate
   devices from different vendors in a standard way.

1.  Introduction

   This document defines a YANG [RFC7950] data model for Address
   Resolution Protocol [RFC826] implementation and identification of
   some common properties within a device.  Devices have common
   properties that need to be configured and monitored in a standard
   way.  This document is intended to present universal ARP protocol
   configuration and many vendors can implement it.

   The data model convers configuration of system parameters of ARP,
   such as static ARP entries, timeout for dynamic ARP entries,
   interface ARP, proxy ARP, and so on.  It also provides information
   about running state of ARP implementations.

1.1.  Terminology

   The key words "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 [RFC6241] and are not redefined
