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 Model
Figure 1 depicts the YANG data model for the AFTR and B4 elements.
The model supports enabling one or more instances of the AFTR
function on a device; each instance is responsible for serving a
group of B4s. The data model assumes that each AFTR instance can: be
enable/disabled, be provisioned with dedicated configuration data,
