YANG [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 OSPFv3 SRv6 [I-D.ietf-lsr-ospfv3-srv6-extensions] and it is an augmentation to the OSPF YANG data model [RFC9129] .¶
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.¶

Tree diagrams used in this document follow the notation defined in [RFC8340].¶
In this document, names of data nodes, actions, and other data model objects are often used without a prefix, as long as it is clear from the context in which YANG module each name is defined. Otherwise, names are prefixed using the standard prefix associated with the corresponding YANG module, as shown in Table 1.¶

This document defines a model for OSPFv3 SRv6 feature. It is an augmentation of the OSPF base model.¶
The OSPFv3 SRv6 YANG module requires support of OSPF base model [RFC9129] which defines basic OSPF configuration and state and support of OSPFv3 Extended LSAs model [I-D.ietf-lsr-ospfv3-extended-lsa-yang].¶
Activation of OSPFv3 SRv6 is done by setting the "enable" leaf to true. This triggers advertisement of SRv6 extensions based on the configuration parameters that have been setup using the base SRv6 module [I-D.ietf-spring-srv6-yang].¶
The SRv6 base module [I-D.ietf-spring-srv6-yang] defines locators. When OSPFv6 SRv6 is enabled, the specified locators are used unless it is enabled to use the default locator. The default locator can be set by using two leafs, i.e.,"default-locator" leaf, "locator-name" leaf.¶
Additional data object (in the OSPFv3 SRv6 model ) for fast reroute [RFC5286] is introduced by augmenting the fast-reroute container of the OSPF module. It brings the ability to activate ipv6 TI-LFA (topology independent LFA) [I-D.ietf-rtgwg-segment-routing-ti-lfa].¶
OSPFv3 SRv6 model augments OSPF module with the micro-loop-avoidance container, this container including the leaf "srv6-enable" brings the ability to activate SRv6 avoid-microloop.¶
The figure below describes the overall structure of the ospfv3-srv6 YANG module:¶

<CODE ENDS>¶
The YANG modules specified in this document define a schema for data that is designed to be accessed via network management protocols, such as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer is the secure transport layer, and the mandatory-to-implement secure transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer is HTTPS, and the mandatory-to-implement secure transport is TLS [RFC8446].¶
The Network Configuration Access Control Model (NACM) [RFC8341] provides the means to restrict access for particular NETCONF or RESTCONF users to a preconfigured subset of all available NETCONF or RESTCONF protocol operations and content.¶
There are a number of data nodes defined in the modules that are writable/creatable/deletable (i.e., config true, which is the default). These data nodes may be considered sensitive or vulnerable in some network environments. Write operations (e.g., edit-config) to these data nodes without proper protection can have a negative effect on network operations. These are the subtrees and data nodes and their sensitivity/vulnerability:¶
