   There exists a class of modems that would benefit from supporting the
   Dynamic Link Exchange Protocol (DLEP) [RFC8175] but do not present a
   single Layer 2 network domain as required by DLEP.  Such devices may

   o  Modems that maintain a varying link to some upstream backbone
      network infrastructure, where the ability to announce link state
      and DLEP metrics is desired, but the concept of a DLEP destination
      router for the backbone does not apply.  Examples of such devices
      can include LTE modems, IEEE 802.11 stations not in ad-hoc mode,
      and some satellite terminals.

   o  Modems that provide Layer 3 wide area network connectivity between
      devices, where remote DLEP destinations do exist, but are not
      directly reachable by MAC address, such as modems that contain
      embedded routing functionality.

   This document introduces an optional extension to the core DLEP
   specification, allowing DLEP to be used between routers and modems
   that operate in this way.


   o  This document is intended as an extension to the core DLEP
      specification, and readers are expected to be fully conversant
      with the operation of core DLEP.
