1.  Introduction

   This document defines a data model for DS-Lite [RFC6333], using the
   YANG data modeling language [RFC6020].  Both the Address Family
   Transition Router (AFTR) and Basic Bridging BroadBand (B4) elements
   are covered by this specification.

   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 YANG Data Models

   Figure 1 depicts the YANG data model for the AFTR, while Figure 2
   shows the YANG data model for the B4 element.

   The AFTR model supports enabling one or more instances of the AFTR
   function on a device; each instance is responsible for serving a
