Abstract

   This document defines a network instance module.  This module along
   with the logical network element module can be used to manage the
   logical and virtual resource representations that may be present on a
   network device.  Examples of common industry terms for logical
   resource representations are Logical Systems or Logical Routers.
   Examples of common industry terms for virtual resource
   representations are Virtual Routing and Forwarding (VRF) instances
   and Virtual Switch Instances (VSIs).

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 make use of the YANG
   functionality enabled by YANG Schema Mount
   [I-D.ietf-netmod-schema-mount].

   Two forms of resource partitioning are supported:

   The first form, which is defined in [I-D.ietf-rtgwg-lne-model],
   provides a logical partitioning of a network device where each
   partition is separately managed as essentially an independent network
   element which is 'hosted' by the base network device.  These hosted
   network elements are referred to as logical network elements, or
   LNEs, and are supported by the logical-network-element module defined
   in [I-D.ietf-rtgwg-lne-model].  The module is used to identify LNEs
   and associate resources from the network-device with each LNE.  LNEs
   themselves are represented in YANG as independent network devices;
