YANG Data Model for OSPF Protocol
draft-ietf-ospf-yang-20
Abstract
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.

1. Overview
YANG [RFC6020][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 [RFC6241]. 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.
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. If fully conforms to the Network Management Datastore
Architecture (NDMA) [RFC8342]. A core routing data model is defined
in [RFC8349], and it provides the basis for the development of data

Internet-Draft OSPF YANG Data Model December 2018
models for routing protocols. The interface data model is defined in
[RFC8343] and is used for referencing interfaces from the routing
protocol. The key-chain data model used for OSPF authentication is
defined in [RFC8177] and provides both a reference to configured key-
chains and an enumeration of cryptographic algorithms.
Both OSPFv2 [RFC2328] and OSPFv3 [RFC5340] are supported. In
addition to the core OSPF protocol, features described in other OSPF
RFCs are also supported. These includes demand circuit [RFC1793],
traffic engineering [RFC3630], multiple address family [RFC5838],
graceful restart [RFC3623] [RFC5187], NSSA [RFC3101], and OSPF(v3) as
a PE-CE Protocol [RFC4577], [RFC6565]. These non-core features are
optional in the OSPF data model.
1.1. Requirements Language
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 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
1.2. Tree Diagrams
This document uses the graphical representation of data models
defined in [RFC8340].
2. Design of Data Model
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 engine is tied to the routing domain, how
multiple protocol engines are be instantiated among others.
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.
2.1. OSPF Operational State
The OSPF operational state is included in the same tree as OSPF
configuration consistent with Network Management Datastore
Architecture [RFC8342]. Consequently, only the routing container in
the ietf-routing model [RFC8349] is augmented. The routing-state
container is not augmented.

2.2. Overview
The OSPF YANG module defined in this document has all the common
building blocks for the OSPF protocol.
The OSPF YANG module augments the /routing/control-plane-protocols/
control-plane-protocol path defined in the ietf-routing module.

The ospf module is intended to match to the vendor specific OSPF
configuration construct that is identified by the local identifier
'name'. The field 'version' allows support for OSPFv2 and OSPFv3.
The ospf container includes one OSPF protocol engine instance. The
instance includes OSPF router level configuration and operational
state.
Yeung, et al. Expires June 19, 2019 [Page 4]
Internet-Draft OSPF YANG Data Model December 2018
The area and area/interface containers respectively define the OSPF
configuration and operational state for OSPF areas and interfaces.
The topologies container defines the OSPF configuration and
operational state for OSPF topologies when the multi-topology feature
is supported.
2.3. OSPFv2 and OSPFv3
The data model defined herein supports both OSPFv2 and OSPFv3.
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.
2.4. Optional Features
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.
This model defines the following optional features:
1. multi-topology: Support Multiple-Topolgy Routing (MTR)
[RFC4915].
2. multi-area-adj: Support OSPF multi-area adjacency [RFC5185].
3. explicit-router-id: Support explicit per-instance Router-ID
specification.
4. demand-circuit: Support OSPF demand circuits [RFC1793].
5. mtu-ignore: Support disabling OSPF Database Description packet
MTU mismatch checking.
6. lls: Support OSPF link-local signaling (LLS) [RFC5613].
7. prefix-suppression: Support OSPF prefix advertisement
suppression [RFC6860].
8. ttl-security: Support OSPF Time to Live (TTL) security check
suppression [RFC5082].
9. nsr: Support OSPF Non-Stop Routing (NSR).
10. graceful-restart: Support Graceful OSPF Restart [RFC3623],
[RFC5187].

11. admin-control: Support Administrative control of the protocol
state.
12. auto-cost: Support OSPF interface cost calculation according to
reference bandwidth [RFC2328].
13. max-ecmp: Support configuration of the maximum number of Equal-
Cost Multi-Path (ECMP) paths.
14. max-lsa: Support configuration of the maximum number of LSAs the
OSPF instance will accept [RFC1765].
15. te-rid: Support configuration of the Traffic Engineering (TE)
Router-ID, i.e., the Router Address described in Section 2.4.1
of [RFC3630] or the Router IPv6 Address TLV described in
Section 3 of [RFC5329].
16. ldp-igp-sync: Support LDP IGP synchronization [RFC5443].
17. ospfv2-authentication-trailer: Support OSPFv2 Authentication

[RFC6987].
26. pe-ce-protocol: Support OSPF as a PE-CE protocol [RFC4577],
[RFC6565].
27. ietf-spf-delay: Support IETF SPF delay algorithm [RFC8405].
Yeung, et al. Expires June 19, 2019 [Page 6]
Internet-Draft OSPF YANG Data Model December 2018
28. bfd: Support BFD detection of OSPF neighbor reachability
[RFC5880], [RFC5881], and [I-D.ietf-bfd-yang].
29. hygrid-interface: Support OSPF Hybrid Broadcast and Point-to-
Point Interfaces [RFC6845].
30. two-part-metric: Support OSPF Two-Part Metric [RFC8042].
It is expected that vendors will support additional features through
vendor-specific augmentations.
2.5. OSPF Router Configuration/Operational State
The ospf container is the top level container in this data model. It
represents an OSPF protocol engine 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.
