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).

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].

   The first form of resource partitioning 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
