1. Overview
YANG [RFC6020] 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. A core routing data model is defined in
[I-D.ietf-netmod-routing-cfg], and it provides the basis for the
development of data models for routing protocols. The interface data
model is defined in [RFC7223] and is used for referencing interfaces
from the routing protocol. The key-chain data model used for OSPF

Internet-Draft OSPF Yang Data Model October 2016
authentication is defined in [I-D.ietf-rtgwg-yang-key-chain] 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", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
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, and configuration
inheritance, 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. 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/routing-instance/routing-
protocols/routing-protocol path defined in the ietf-routing module.

+--rw topologies
+--rw topology* [name]
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 or more OSPF protocol engines, each
enclosed in a separate instance entity. Each instance includes
information for the routing domain based on the [routing-instance af]
specification. There is no default routing domain assumed by the
data model. For example, to enable OSPF on a vendor's default IPv4
routing domain, an explicit instance entity with a specification like
Yeung, et al. Expires May 4, 2017 [Page 4]
Internet-Draft OSPF Yang Data Model October 2016
["default" "ipv4-unicast"] is required. The instance also contains
OSPF router level configuration
The instance/area and instance/area/interface containers respectively
define the OSPF configuration for OSPF areas and interfaces.
The instance/topology container defines the OSPF configuration for
OSPF topologies when the multi-topology feature is supported.
2.2. 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.
2.3. 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 a number of features, such as NSR, max-LSA, etc.
It is expected that vendors will support additional features through
vendor specific augmentations.
2.4. Inheritance
This data model supports configuration inheritance at different
levels including instance-level, area-level, and interface-level
inheritance.
The all-instances-inherit, all-areas-inherit, and all-interfaces-
inherit containers are defined to provide a consistent way to
configure inheritable configuration parameters. For example,
parameters defined in the all-instances-inherit container apply to
all OSPF instances. However, a particular instance configuration can
include leaves that override this inheritance.
Inheritance is defined as an optional feature, and vendors are
permitted to augment the inheritance containers with their own vendor
specific parameters.

2.5. OSPF Router Configuration
The ospf container is the top level container in this data model. It
contains shared information among the OSPF instances configured
within the container.

instance is dictated through the specification of [routing-instance
af].

be inherited by configured OSPF areas in the OSPF instance.

3. OSPF BFD Yang Module
Additionally, this document defines a module that can be used to
configure and monitor the OSPF BFD feature.
Bidirectional Forwarding Detection (BFD) [RFC5880] is a network
protocol that is used for liveness detection of arbitrary paths
between systems. A YANG data model is defined in [I-D.ietf-bfd-yang]
that supports BFD configuration and management.
As a client of BFD, the OSPF protocol uses the services provided by
BFD. The OSPF BFD YANG augments the base OSPF module and is defined
as a separate module. Hence, an implementation that does not support
BFD can still use the OSPF base model without having to import the
BFD module [I-D.ietf-bfd-yang].
