<abstract>
<t>This document defines a YANG data model that can be
used to configure and manage OSPF. 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"/> 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 and it is an augmentation to the core routing data model.
It fully conforms to the Network Management Datastore Architecture (NDMA)
<xref target="RFC8342"/>.
A core routing data model is defined in
<xref target="RFC8349"></xref>,
and it provides the basis for the development of data models for routing
protocols. The interface data model is defined in
<xref target="RFC8343"></xref> and is used for referencing
interfaces from the routing protocol. The key-chain data model used for
OSPF authentication is defined in <xref target="RFC8177"></xref>
and provides both a reference to configured key-chains and an
enumeration of cryptographic algorithms.</t>
<t>Both OSPFv2 <xref target="RFC2328"></xref> and OSPFv3
<xref target="RFC5340"></xref> are supported. In addition to
the core OSPF protocol, features described in other
OSPF RFCs are also supported. These includes demand circuit
<xref target="RFC1793"></xref>, traffic engineering <xref target="RFC3630"></xref>,
multiple address family <xref target="RFC5838"></xref>, graceful restart
<xref target="RFC3623"></xref> <xref target="RFC5187"></xref>,
NSSA <xref target="RFC3101"></xref>, and OSPFv2 or OSPFv3 as a PE-CE Protocol
<xref target="RFC4577"></xref>, <xref target="RFC6565"></xref>.
These non-core features are optional in the OSPF data model.</t>
<section title="Requirements Language">
<t>The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED",
"MAY", and "OPTIONAL" in this document are to be interpreted as
described in BCP 14 <xref target="RFC2119"/> <xref target="RFC8174"/>
when, and only when, they appear in all capitals, as shown here.</t>
</section>
<section title="Tree Diagrams">
<t>This document uses the graphical representation of data models
defined in <xref target="RFC8340"/>.</t>
</section>
</section>
<section title="Design of Data Model">
<t>Although the basis of OSPF configuration elements like routers,
areas, and interfaces remains the same, the detailed configuration
model varies among router vendors. Differences are observed in terms
of how the protocol instance is tied to the routing domain, how multiple
protocol instances are be instantiated among others.</t>
<t>The goal of this document is to define a data model that provides a common user
interface to the OSPFv2 and OSPFv3 protocols. There is very little information that is
designated as "mandatory", providing freedom for vendors to adapt this data model to their
respective product implementations.</t>
<section title="OSPF Operational State">
<t>The OSPF operational state is included in the same tree as OSPF configuration
consistent with the Network Management Datastore Architecture
<xref target="RFC8342"></xref>. Consequently, only the routing container
in the ietf-routing model <xref target="RFC8349"/> is augmented. The routing-state container
is not augmented.</t>
</section>
<section title="Overview">
<t>The OSPF YANG module defined in this document has all the common building
blocks for the OSPF protocol.</t>
<t>The OSPF YANG module augments the /routing/control-plane-protocols/control-plane-protocol
path defined in the ietf-routing module. The ietf-ospf model defines a single instance of
OSPF which may be instantiated as an OSPFv2 or OSPFv3 instance. Multiple instances are
instantiated as multiple control-plane protocols instances.</t>

<t>The ospf module is intended to match to the vendor specific
OSPF configuration construct that is identified by the local identifier 'name'.</t>
<t>The ospf container includes one OSPF protocol instance.
The instance includes OSPF router level configuration and operational
state.</t>
<t>The area and area/interface containers
define the OSPF configuration and operational state for OSPF areas
and interfaces respectively.</t>
<t>The topologies container defines the OSPF configuration and operational
state for OSPF topologies when the multi-topology feature is supported.</t>
</section>
<section title="OSPFv2 and OSPFv3">
<t>The data model defined herein supports both OSPFv2 and OSPFv3.</t>
<t>The field 'version' is used to indicate the OSPF version and is
mandatory. Based on the configured version, the data model varies
to accommodate the differences between OSPFv2 and OSPFv3.</t>
</section>
<section title="Optional Features">
<t>Optional features are beyond the basic OSPF configuration and
it is the responsibility of each vendor to decide whether to
support a given feature on a particular device.</t>
<t>This model defines the following optional features:
<list style="numbers">
<t>multi-topology: Support Multi-Topology Routing (MTR)
<xref target="RFC4915"/>.</t>
<t>multi-area-adj: Support OSPF multi-area adjacency
<xref target="RFC5185"/>.</t>
<t>explicit-router-id: Support explicit per-instance Router-ID
specification.</t>
<t>demand-circuit: Support OSPF demand circuits
<xref target="RFC1793"/>.</t>
<t>mtu-ignore: Support disabling OSPF Database Description
packet MTU mismatch checking.</t>
<t>lls: Support OSPF link-local signaling (LLS)
<xref target="RFC5613"/>.</t>
<t>prefix-suppression: Support OSPF prefix advertisement
suppression <xref target="RFC6860"/>.</t>
<t>ttl-security: Support OSPF Time to Live (TTL) security check
support <xref target="RFC5082"/>.</t>
<t>nsr: Support OSPF Non-Stop Routing (NSR). The OSPF NSR feature allows
a router with redundant control-plane capability (e.g., dual Route-Processor (RP)
cards) to maintain its state and adjacencies during planned and unplanned
control-plane processing restarts. It differs from graceful-restart or Non-Stop
Forwarding (NSF) in that no protocol signaling or assistance from adjacent OSPF
neighbors is required to recover control-plane state.</t>
<t>graceful-restart: Support Graceful OSPF Restart
<xref target="RFC3623"/>, <xref target="RFC5187"/>.</t>
<t>auto-cost: Support OSPF interface cost calculation according to
reference bandwidth <xref target="RFC2328"/>.</t>
<t>max-ecmp: Support configuration of the maximum number of
Equal-Cost Multi-Path (ECMP) paths.</t>
<t>max-lsa: Support configuration of the maximum number of LSAs
the OSPF instance will accept <xref target="RFC1765"/>.</t>
<t>te-rid: Support configuration of the Traffic Engineering (TE)
Router-ID, i.e., the Router Address described in Section 2.4.1
of <xref target="RFC3630"/> or the Router IPv6 Address TLV
described in Section 3 of <xref target="RFC5329"/>.</t>
<t>ldp-igp-sync: Support LDP IGP synchronization
<xref target="RFC5443"/>.</t>
<t>ospfv2-authentication-trailer: Support OSPFv2 Authentication
trailer as specified in <xref target="RFC5709"/> or
<xref target="RFC7474"/>.</t>
<t>ospfv3-authentication-ipsec: Support IPsec for OSPFv3
authentication <xref target="RFC4552"/>.</t>
<t>ospfv3-authentication-trailer: Support OSPFv3 Authentication
trailer as specified in <xref target="RFC7166"/>.</t>
<t>fast-reroute: Support IP Fast Reroute (IP-FRR)
<xref target="RFC5714"/>.</t>
<t>node-flag: Support node-flag for OSPF prefixes.
<xref target="RFC7684"/>.</t>
<t>node-tag: Support node admin tag for OSPF instances
<xref target="RFC7777"/>.</t>
<t>lfa: Support Loop-Free Alternates (LFAs)
<xref target="RFC5286"/>.</t>
<t>remote-lfa: Support Remote Loop-Free Alternates (R-LFA)
<xref target="RFC7490"/>.</t>
<t>stub-router: Support RFC 6987 OSPF Stub Router
advertisement <xref target="RFC6987"/>.</t>
<t>pe-ce-protocol: Support OSPF as a PE-CE protocol
<xref target="RFC4577"/>, <xref target="RFC6565"/>.</t>
<t>ietf-spf-delay: Support IETF SPF delay algorithm
<xref target="RFC8405"/>.</t>
<t>bfd: Support BFD detection of OSPF neighbor reachability
<xref target="RFC5880"/>, <xref target="RFC5881"/>,
and <xref target="I-D.ietf-bfd-yang"/>.</t>
<t>hybrid-interface: Support OSPF Hybrid Broadcast and Point-to-Point
Interfaces <xref target="RFC6845"/>.</t>
</list></t>
<t>It is expected that vendors will support additional
features through vendor-specific augmentations.</t>
</section>
<section title="OSPF Router Configuration/Operational State">
<t>The ospf container is the top-level container in this data model.
It represents an OSPF protocol instance and contains the router level
configuration and operational state.
The operational state includes the instance statistics, IETF SPF delay statistics,
AS-Scoped Link State Database, local RIB, SPF Log, and the LSA log.</t>
