1. Introduction
This document defines a YANG [RFC7950] data model for describing the
relationship between a layer 3 network topology
[I-D.ietf-i2rs-yang-l3-topology] and a TE topology
[I-D.ietf-teas-yang-te-topo].
When traffic engineering is enabled on a layer 3 network topology,
there will be a corresponding TE topology. The TE topology may or
may not be congruent to the layer 3 network topology. When such a
congruent TE topology exists, there will be a one-to-one association
between the one modeling element in the layer 3 topology to another
element in the TE topology. When such a congruent TE topology does
not exist, the association will not be one-to-one. This YANG data
model allows both cases.
1.1. Terminology
The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
Liu, et al. Expires September 14, 2017 [Page 2]
Internet-Draft YANG L3 TE Topology March 2017
"OPTIONAL" in this document are to be interpreted as described in BCP
14, [RFC2119].
The following terms are defined in [RFC7950] and are not redefined
here:
o augment
o data model
o data node
2. Modeling Considerations
2.1. Relationship Between Layer 3 Topology and TE topology
In general, layer 3 network topology model and TE topology model can
be used independently. When traffic engineering is enabled on a
layer 3 network topology, there will be associations between objects
in layer 3 network topologies and objects in TE topologies. The
properties of these relations are:
o The associations are between objects of the same class, i.e. node
to node or link to link.
o The multiplicity of such an association is: 0..1 to 0..1. An
object in a layer 3 network may have zero or one associated object
in the corresponding TE network.
2.2. Relationship Modeling
YANG data type leafref is used to model the association relationship
between a layer 3 network topology and a TE topology. YANG must
statements are used to enforce the referenced objects are in the
topologies of proper type.
3. Model Structure
3.1. Layer 3 TE Topology Module
The model tree structure of the layer 3 TE topology module is as
shown below:

6. Security Considerations
The configuration, state, action and notification data defined in
this document are designed to be accessed via the NETCONF protocol
[RFC6241]. The data-model by itself does not create any security
implications. The security considerations for the NETCONF protocol
are applicable. The NETCONF protocol used for sending the data
supports authentication and encryption.
