YANG [RFC7950] is a data definition language used to define the contents of a conceptual datastore 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., RESTCONF [RFC8040]) 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 Command-Line Interfaces (CLIs) and programmatic APIs.
Yang [RFC7950]は、NetConf [RFC6241]を使用してネットワークデバイスを管理できるようにする概念データストアの内容を定義するために使用されるデータ定義言語です。Yangは、初期の範囲を超えて他のインターフェイスへのバインディング（RestConf [RFC8040]など）とXML以外のエンコーディング（JSONなど）以外のエンコーディングが定義されていることを証明しています。さらに、Yangデータモデルは、コマンドラインインターフェイス（CLI）やプログラムAPIなど、他のインターフェイスの実装の基礎として使用できます。
This document defines a YANG data model augmenting the IETF OSPF YANG data model [RFC9129], which itself augments [RFC8349], to provide support for configuration and operational state for OSPFv3 Extended Link State Advertisements (LSAs) as defined in [RFC8362].
このドキュメントは、[RFC8349]を増強するIETF OSPF Yangデータモデル[RFC9129]を増強するYangデータモデルを定義し、[RFC8362]で定義されているOSPFV3拡張リンク状態広告（LSA）の構成と運用状態をサポートします。
The YANG module specified in this document conforms to the Network Management Datastore Architecture (NMDA) [RFC8342].
このドキュメントで指定されたYangモジュールは、ネットワーク管理データストアアーキテクチャ（NMDA）[RFC8342]に適合しています。
This document uses the graphical representation of data models defined in [RFC8340].
このドキュメントでは、[RFC8340]で定義されたデータモデルのグラフィカルな表現を使用しています。
This document defines a YANG data model for the OSPFv3 Extended LSA feature. It is an augmentation of the OSPF base model [RFC9129] to provide support for OSPFv3 LSA Extensibility [RFC8362]. OSPFv3 Extended LSAs provide extensible TLV-based LSAs for the base LSA types defined in [RFC5340].
このドキュメントでは、OSPFV3拡張LSA機能のYangデータモデルを定義しています。OSPFv3 LSA拡張性[RFC8362]のサポートを提供するためのOSPFベースモデル[RFC9129]の増強です。OSPFV3拡張LSAは、[RFC5340]で定義された塩基LSAタイプに拡張可能なTLVベースのLSAを提供します。
The OSPFv3 Extended LSA YANG module requires support for the OSPF base model, which defines basic OSPF configuration and state. The OSPF YANG data model augments the "ietf-routing" YANG data model defined in [RFC8349]. The augmentations defined in the "ietf-ospfv3- extended-lsa" YANG module provide global configuration, area configuration, and the addition of OSPFv3 Extended LSAs to the Link State Database (LSDB) operational state.
OSPFV3拡張LSA Yangモジュールには、基本的なOSPF構成と状態を定義するOSPFベースモデルのサポートが必要です。OSPF Yangデータモデルは、[RFC8349]で定義されている「IETFルーティング」Yangデータモデルを増強します。「IETF -OSPFV3-拡張LSA」YANGモジュールで定義された増強は、グローバル構成、エリア構成、およびOSPFV3の追加により、LSAをリンク状態データベース（LSDB）運用状態に拡張しました。

The YANG module specified in this document defines 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].
このドキュメントで指定されたYangモジュールは、NetConf [RFC6241]やRestConf [RFC8040]などのネットワーク管理プロトコルを介してアクセスするように設計されたデータのスキーマを定義しています。最低のネットコン層は安全な輸送層であり、実装から実装の安全な輸送は安全なシェル（SSH）[RFC6242]です。最も低いRESTCONF層はHTTPSであり、実装対象の安全な輸送はTLS [RFC8446]です。
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.
ネットワーク構成アクセス制御モデル（NACM）[RFC8341]は、利用可能なすべてのNetConfまたはRestConfプロトコル操作とコンテンツの事前に設定されたサブセットに特定のNetConfまたはRestConfユーザーのアクセスを制限する手段を提供します。
There are a number of data nodes defined in the "ietf-ospfv3- extended-lsa.yang" module 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:
「ietf-ospfv3- extended-lsa.yang」モジュールで定義されている多くのデータノードがあります。これらのデータノードは、一部のネットワーク環境で敏感または脆弱と見なされる場合があります。適切な保護なしにこれらのデータノードに操作を書き込む（例：編集config）は、ネットワーク操作に悪影響を与える可能性があります。これらは、サブツリーとデータノードとその感度/脆弱性です。

/OSPF：OSPF/Extended-LSA-Support
/ospf:ospf/ospf:areas/ospf:area/extended-lsa-support
/OSPF：OSPF/OSPF：AREAGE/OSPF：AREA/Extended-LSA-Support
The ability to disable or enable OSPFv3 Extended LSA support can result in a Denial-of-Service (DoS) attack, since OSPFv3 routers will use solely OSPFv3 Extended LSAs or OSPFv3 Legacy LSAs for the OSPFv3 SPF computation. OSPFv3 routers using different types of LSAs will result in incomplete reachability and possible partitioning of the OSPFv3 routing domain. Refer to Section 6 of [RFC8362] for more information on OSPFv3 Extended LSA compatibility.
OSPFV3ルーターはOSPFV3 SPF計算にOSPFV3拡張LSAまたはOSPFV3レガシーLSAのみを使用するため、OSPFV3拡張LSAサポートを無効または有効にする機能は、サービス拒否（DOS）攻撃をもたらす可能性があります。さまざまなタイプのLSAを使用してOSPFV3ルーターは、OSPFV3ルーティングドメインの到達可能性と分割の可能性が不完全になります。[RFC8362]のセクション6を参照してください。OSPFV3の拡張LSA互換性の詳細については。
Some of the readable data nodes in the "ietf-ospfv3-extended-lsa.yang" module may be considered sensitive or vulnerable in some network environments. It is thus important to control read access (e.g., via get, get-config, or notification) to these data nodes.
「IETF -OSPFV3-EXTENDEDED-LSA.YANG」モジュールの読み取り可能なデータノードの一部は、一部のネットワーク環境で敏感または脆弱と見なされる場合があります。したがって、これらのデータノードへの読み取りアクセス（GET、GetConfig、または通知を介して）を制御することが重要です。
Exposing the Link State Database (LSDB) will in turn expose the detailed topology of the network. This includes topological information from other routers. This may be undesirable due to the fact that exposure may facilitate other attacks. Additionally, network operators may consider their topologies to be sensitive confidential data.
リンク状態データベース（LSDB）を公開すると、ネットワークの詳細なトポロジが公開されます。これには、他のルーターからのトポロジー情報が含まれます。これは、曝露が他の攻撃を促進する可能性があるため、望ましくない可能性があります。さらに、ネットワークオペレーターは、トポロジーが機密性のある機密データであると考える場合があります。
