<abstract>
<t>This document defines a YANG data model that can be
used to configure and manage OSPF Segment Routing. The model is based on
YANG 1.1 as defined in RFC 7950 and conforms to the
Network Management Datastore Architecture (NDMA) as described
in RFC 8342.</t>
</abstract>
</front>
<middle>
<section title="Overview">
<t>YANG <xref target="RFC6020"></xref> <xref target="RFC7950"></xref> is a data definition language
used to define the contents of a conceptual data store
that allows networked devices to be managed using NETCONF
<xref target="RFC6241"></xref>. YANG is proving relevant beyond its
initial confines, as bindings to other interfaces (e.g., ReST) and
encodings other than XML (e.g., JSON) are being defined. Furthermore,
YANG data models can be used as the basis for implementation of other
interfaces, such as CLI and programmatic APIs.</t>
<t>This document defines a YANG data model that can be used to configure
and manage OSPF Segment Routing and it is an augmentation to the OSPF YANG data model.
</t>
<t> The YANG modules in this document conform to the Network Management
