Abstract

   This document defines a logical network element module.  This module
   along with the network instance 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 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 a YANG [RFC6020] module to support the creation
   of logical network elements on a network device.  A logical network
   element (LNE) is an independently managed virtual device made up of
   resources allocated to it from the host, or parent, network device.
   (An LNE running on a host network device conceptually parallels a
   virtual machine running on a host system.)  Using host-virtualization
   terminology one could refer to an LNE as a "Guest", and the
   containing network-device as the "Host".  While LNEs may be
   implemented via host-virtualization technologies this is not a
   requirement.

   This document also defines the necessary augmentations for allocating
   host resources to a given LNE.  As the interface management model
   [RFC7223] is the only a module that currently defines host resources,
