1.  Introduction

   This document defines a data model for DS-Lite [RFC6333], using the
   YANG data modeling language [RFC6020].  Only the Address Family
   Transition Router (AFTR) element is covered by this specification.
   As a reminder, [RFC6334] can be used to configure the name of the
   AFTR to a Basic Bridging BroadBand (B4) element.

   DS-Lite deployment considerations are discussed in [RFC6908].

   This document follows the guidelines of [RFC6087].

   This document uses the common YANG types defined in [RFC6991].

1.1.  Terminology

   This document makes use of the terms defined in [RFC6333].

   The terminology for describing YANG data models is defined in
   [RFC6020].

1.2.  Tree Diagrams

   The meaning of the symbols in these diagrams is as follows:

   o  Brackets "[" and "]" enclose list keys.

   o  Curly braces "{" and "}" contain names of optional features that
      make the corresponding node conditional.

   o  Abbreviations before data node names: "rw" means configuration
      (read-write), "ro" state data (read-only).

   o  Symbols after data node names: "?" means an optional node, "!" a
      container with presence, and "*" denotes a "list" or "leaf-list".

   o  Parentheses enclose choice and case nodes, and case nodes are also
      marked with a colon (":").

   o  Ellipsis ("...") stands for contents of subtrees that are not
      shown.

2.  DS-Lite AFTR YANG Data Model

   Figure 1 depicts the YANG data model for the AFTR element.

   A device can enable multiple AFTR instances; each responsible to
   service a group of B4s.  The data model assumes that each AFTR
   instance can: be enable/disabled, be provisioned with a dedicated
