                    YANG Model for Network Instances
                      draft-ietf-rtgwg-ni-model-10

Abstract

   This document defines a network instance module.  This module can be
   used to manage the virtual resource partitioning that may be present
   on a network device.  Examples of common industry terms for virtual
   resource partitioning are Virtual Routing and Forwarding (VRF)
   instances and Virtual Switch Instances (VSIs).

   The YANG model in this document conforms to the Network Management
   Datastore Architecture defined in I-D.ietf-netmod-revised-datastores.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
   working documents as Internet-Drafts.  The list of current Internet-
   Drafts is at http://datatracker.ietf.org/drafts/current/.

   Internet-Drafts are draft documents valid for a maximum of six months

1.  Introduction

   This document defines the second of two new modules that are defined
   to support the configuration and operation of network-devices that
   allow for the partitioning of resources from both, or either,
   management and networking perspectives.  Both leverage the YANG
   functionality enabled by YANG Schema Mount
   [I-D.ietf-netmod-schema-mount].
