YANG [RFC6020] [RFC7950] is a data definition language that was introduced to model the configuration and running state of a device managed using network management protocols such as NETCONF [RFC6241] or RESTCONF [RFC8040]. YANG is now also being used as a component of wider management interfaces, such as command-line interfaces (CLIs).
YANG [RFC6020] [RFC7950]は、NETCONF [RFC6241]やRESTCONF [RFC8040]などのネットワーク管理プロトコルを使用して管理されるデバイスの構成と実行状態をモデル化するために導入されたデータ定義言語です。 YANGは現在、コマンドラインインターフェイス（CLI）などのより広い管理インターフェイスのコンポーネントとしても使用されています。
This document defines a YANG data model that can be used to configure and manage Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) devices. The protocol versions include IGMPv1 [RFC1112], IGMPv2 [RFC2236], IGMPv3 [RFC3376], MLDv1 [RFC2710], and MLDv2 [RFC3810]. The core features of the IGMP and MLD protocols are defined as required. Non-core features are defined as optional in the provided data model.

The model covers IGMPv1 [RFC1112], IGMPv2 [RFC2236], IGMPv3 [RFC3376], MLDv1 [RFC2710], and MLDv2 [RFC3810].
モデルはIGMPv1 [RFC1112]、IGMPv2 [RFC2236]、IGMPv3 [RFC3376]、MLDv1 [RFC2710]、およびMLDv2 [RFC3810]をカバーしています。
This model does not cover other IGMP- and MLD-related protocols such as IGMP/MLD Proxy [RFC4605] or IGMP/MLD Snooping [RFC4541] etc., which will be specified in separate documents.
このモデルは、IGMP / MLDプロキシ[RFC4605]やIGMP / MLDスヌーピング[RFC4541]など、他のドキュメントで指定される他のIGMPおよびMLD関連プロトコルには対応していません。
This model can be used to configure and manage various versions of IGMP and MLD protocols. The operational state data and statistics can be retrieved by this model. Even though no protocol-specific notifications are defined in this model, the subscription and push mechanism defined in [RFC8639] and [RFC8641] can be implemented by the user to subscribe to notifications on the data nodes in this model.
このモデルは、IGMPおよびMLDプロトコルのさまざまなバージョンを構成および管理するために使用できます。このモデルにより、動作状態データと統計を取得できます。このモデルではプロトコル固有の通知は定義されていませんが、[RFC8639]および[RFC8641]で定義されているサブスクリプションおよびプッシュメカニズムをユーザーが実装して、このモデルのデータノードの通知をサブスクライブできます。
The model contains all the basic configuration parameters to operate the protocols listed above. Depending on the implementation choices, some systems may not allow some of the advanced parameters to be configurable. The occasionally implemented parameters are modeled as optional features in this model, while the rarely implemented parameters are not included in this model and left for augmentation. This model can be extended, and it has been structured in a way that such extensions can be conveniently made.
モデルには、上記のプロトコルを操作するためのすべての基本的な構成パラメーターが含まれています。実装の選択によっては、一部のシステムでは、一部の高度なパラメータを構成できない場合があります。まれに実装されるパラメーターはこのモデルに含まれておらず、拡張のために残されていますが、時々実装されるパラメーターはこのモデルのオプション機能としてモデル化されています。このモデルは拡張可能であり、そのような拡張が便利に行えるように構成されています。
The protocol parameters covered in this model can been seen from the model structure described in Section 3.
このモデルでカバーされるプロトコルパラメータは、セクション3で説明されているモデル構造から見ることができます。
The protocol parameters that were considered but are not covered in this model are described in the following sections.
考慮されたが、このモデルではカバーされていないプロトコルパラメータについては、次のセクションで説明します。
The configuration parameters and operational states not covered on an IGMP instance or an MLD instance are:
IGMPインスタンスまたはMLDインスタンスでカバーされていない構成パラメーターと動作状態は次のとおりです。

This model is designed to represent the capabilities of IGMP and MLD devices with various specifications, including the basic capability subsets of the IGMP and MLD protocols. The main design goals of this document are that the basic capabilities described in the model are supported by any major now-existing implementation, and that the configuration of all implementations meeting the specifications is easy to express through some combination of the optional features in the model and simple vendor augmentations.
このモデルは、IGMPおよびMLDプロトコルの基本機能サブセットを含む、さまざまな仕様でIGMPおよびMLDデバイスの機能を表すように設計されています。このドキュメントの主な設計目標は、モデルに記述されている基本的な機能が現在存在する主要な実装によってサポートされていること、および仕様を満たすすべての実装の構成が、モデルのオプション機能の組み合わせによって簡単に表現できることです。シンプルなベンダー拡張。
There is also value in widely supported features being standardized, to provide a standardized way to access these features, to save work for individual vendors, and so that mapping between different vendors' configuration is not needlessly complicated. Therefore, this model declares a number of features representing capabilities that not all deployed devices support.
広くサポートされている機能が標準化され、これらの機能にアクセスする標準化された方法を提供し、個々のベンダーの作業を節約し、異なるベンダーの構成間のマッピングが不必要に複雑にならないようにすることにも価値があります。したがって、このモデルは、展開されたすべてのデバイスがサポートするわけではない機能を表すいくつかの機能を宣言します。
The extensive use of feature declarations should also substantially simplify the capability negotiation process for a vendor's IGMP and MLD implementations.
機能宣言を広範囲に使用すると、ベンダーのIGMPおよびMLD実装の機能ネゴシエーションプロセスも大幅に簡略化されます。
On the other hand, operational state parameters are not so widely designated as features, as there are many cases where the defaulting of an operational state parameter would not cause any harm to the system, and it is much more likely that an implementation without native support for a piece of operational state would be able to derive a suitable value for a state variable that is not natively supported.
一方、動作状態パラメータは、機能としてあまり広く指定されていません。動作状態パラメータのデフォルト設定がシステムに悪影響を与えない場合が多く、ネイティブサポートなしの実装の可能性がはるかに高いためです。動作状態の一部は、ネイティブにサポートされていない状態変数の適切な値を導出できます。
The protocol IGMP only supports IPv4, while the protocol MLD only supports IPv6. The data model defined in this document can be used for both IPv4 and IPv6 address families.
プロトコルIGMPはIPv4のみをサポートし、プロトコルMLDはIPv6のみをサポートします。このドキュメントで定義されているデータモデルは、IPv4とIPv6の両方のアドレスファミリで使用できます。
This document defines IGMP and MLD as separate schema branches in the structure. The benefits are:
このドキュメントでは、構造内の別々のスキーマブランチとしてIGMPとMLDを定義しています。利点は次のとおりです。
* The model can support IGMP (IPv4), MLD (IPv6), or both optionally and independently. Such flexibility cannot be achieved cleanly with a combined branch.
* モデルは、IGMP（IPv4）、MLD（IPv6）、またはオプションと独立の両方をサポートできます。このような柔軟性は、組み合わせたブランチではきれいに達成することはできません。
* The structure is consistent with other YANG data models such as RFC 8344, which uses separate branches for IPv4 and IPv6.
* この構造は、IPv4とIPv6に別々のブランチを使用するRFC 8344などの他のYANGデータモデルと一致しています。
* The separate branches for IGMP and MLD can accommodate their differences better and cleaner. The two branches can better support different features and node types.
* IGMPとMLDの別々のブランチは、それらの違いをよりよく、より明確に対応できます。 2つのブランチは、さまざまな機能とノードタイプをより適切にサポートできます。
This model augments the core routing data model specified in [RFC8349].
このモデルは、[RFC8349]で指定されているコアルーティングデータモデルを補強します。

The "igmp" container instantiates an IGMP protocol of version IGMPv1, IGMPv2, or IGMPv3. The "mld" container instantiates an MLD protocol of version MLDv1 or MLDv2.

The YANG data model defined in this document conforms to the Network Management Datastore Architecture (NMDA) [RFC8342]. The operational state data is combined with the associated configuration data in the same hierarchy [RFC8407].
このドキュメントで定義されているYANGデータモデルは、ネットワーク管理データストアアーキテクチャ（NMDA）[RFC8342]に準拠しています。動作状態データは、同じ階層で関連する構成データと結合されます[RFC8407]。
A configuration data node is marked as mandatory only when its value must be provided by the user. Where nodes are not essential to protocol operation, they are marked as optional. Some other nodes are essential but have a default specified, so that they are also optional and need not be configured explicitly.
構成データノードは、その値をユーザーが指定する必要がある場合にのみ必須としてマークされます。ノードがプロトコル操作に必須ではない場合、それらはオプションとしてマークされます。他のいくつかのノードは必須ですが、デフォルトが指定されているため、それらもオプションであり、明示的に構成する必要はありません。
The IGMP data is modeled as a schema subtree augmenting the "control-plane-protocol" data node under "/rt:routing/rt:control-plane-protocols" in the module ietf-routing, following the convention described in [RFC8349]. The augmentation to the module ietf-routing allows this model to support multiple instances of IGMP, but a restriction MAY be added depending on the implementation and the device. The identity "igmp" is derived from the "rt:control-plane-protocol" base identity and indicates that a control-plane-protocol instance is IGMP.
IGMPデータは、[RFC8349]で説明されている規則に従って、モジュールietf-routingの「/ rt：routing / rt：control-plane-protocols」の下にある「control-plane-protocol」データノードを補強するスキーマサブツリーとしてモデル化されます。 。モジュールietf-routingの拡張により、このモデルはIGMPの複数のインスタンスをサポートできますが、実装とデバイスに応じて制限が追加される場合があります。アイデンティティ「igmp」は「rt：control-plane-protocol」ベースアイデンティティから派生し、コントロールプレーンプロトコルインスタンスがIGMPであることを示します。
The IGMP subtree is a three-level hierarchy structure as listed below:
IGMPサブツリーは、以下に示す3レベルの階層構造です。
Global level: Including IGMP configuration and operational state attributes for the entire IGMP protocol instance in this router.
グローバルレベル：このルーターのIGMPプロトコルインスタンス全体のIGMP構成および動作状態属性を含みます。
Interface-global level: Including configuration data nodes that are applicable to all the interfaces whose corresponding nodes are not defined or not configured at the interface level. For such a node at the interface level, the system uses the same value of the corresponding node at the interface-global level.
インターフェースグローバルレベル：対応するノードがインターフェースレベルで定義されていない、または構成されていないすべてのインターフェースに適用可能な構成データノードを含みます。インターフェースレベルのそのようなノードの場合、システムは、インターフェースグローバルレベルの対応するノードと同じ値を使用します。
Interface level: Including IGMP configuration and operational state attributes specific to the given interface. For a configuration node at the interface level, there may exist a corresponding configuration node with the same name at the interface-global level. The value configured on a node at the interface level overrides the value configured on the corresponding node at the interface-global level.
インターフェイスレベル：特定のインターフェイスに固有のIGMP構成および動作状態属性を含みます。インターフェースレベルの構成ノードの場合、インターフェースグローバルレベルに同じ名前の対応する構成ノードが存在する場合があります。インターフェースレベルのノードで構成された値は、インターフェースグローバルレベルの対応するノードで構成された値を上書きします。

<CODE ENDS>
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ている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ます。最下層のNETCONF層はセキュアなトランスポート層であり、実装に必須のセキュアなトランスポートはセキュアシェル（SSH）[RFC6242]です。最下位のRESTCONFレイヤーはHTTPSであり、実装に必須のセキュアなトランスポートは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、特定のNETCONFまたはRESTCONFユーザーのアクセスを、利用可能なすべてのNETCONFまたはRESTCONFプロトコル操作およびコンテンツの事前構成されたサブセットに制限する手段を提供します。
There are a number of data nodes defined in this 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:
このYANGモジュールには、書き込み/作成/削除が可能なデータノードがいくつか定義されています（つまり、config true、デフォルトです）。これらのデータノードは、一部のネットワーク環境では機密または脆弱である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書き込み操作（edit-configなど）を行うと、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、およびそれらの機密性/脆弱性です。
Under /rt:routing/rt:control-plane-protocols /rt:control-plane-protocol/igmp-mld:igmp,
/ rt：routing / rt：control-plane-protocols / rt：control-plane-protocol / igmp-mld：igmpの下で、
igmp-mld:global This subtree specifies the configuration for the IGMP attributes at the global level on an IGMP instance. Modifying the configuration can cause IGMP membership to be deleted or reconstructed on all the interfaces of an IGMP instance.
igmp-mld：globalこのサブツリーは、IGMPインスタンスのグローバルレベルでのIGMP属性の構成を指定します。構成を変更すると、IGMPインスタンスのすべてのインターフェースでIGMPメンバーシップが削除または再構築される可能性があります。
igmp-mld:interfaces This subtree specifies the configuration for the IGMP attributes at the interface-global level on an IGMP instance. Modifying the configuration can cause IGMP membership to be deleted or reconstructed on all the interfaces of an IGMP instance.
igmp-mld：interfacesこのサブツリーは、IGMPインスタンスのインターフェイスグローバルレベルでIGMP属性の構成を指定します。構成を変更すると、IGMPインスタンスのすべてのインターフェースでIGMPメンバーシップが削除または再構築される可能性があります。
igmp-mld:interfaces/interface This subtree specifies the configuration for the IGMP attributes at the interface level on an IGMP instance. Modifying the configuration can cause IGMP membership to be deleted or reconstructed on a specific interface of an IGMP instance.
igmp-mld：interfaces / interfaceこのサブツリーは、IGMPインスタンスのインターフェースレベルでのIGMP属性の構成を指定します。構成を変更すると、IGMPメンバーシップが削除されたり、IGMPインスタンスの特定のインターフェースで再構築されたりする可能性があります。
Under /rt:routing/rt:control-plane-protocols /rt:control-plane-protocol/igmp-mld:mld,
/ rt：routing / rt：control-plane-protocols / rt：control-plane-protocol / igmp-mld：mldの下で、
igmp-mld:global This subtree specifies the configuration for the MLD attributes at the global level on an MLD instance. Modifying the configuration can cause MLD membership to be deleted or reconstructed on all the interfaces of an MLD instance.
igmp-mld：globalこのサブツリーは、MLDインスタンスのグローバルレベルでMLD属性の構成を指定します。構成を変更すると、MLDインスタンスのすべてのインターフェースでMLDメンバーシップが削除または再構築される可能性があります。
igmp-mld:interfaces This subtree specifies the configuration for the MLD attributes at the interface-global level on an MLD instance. Modifying the configuration can cause MLD membership to be deleted or reconstructed on all the interfaces of an MLD instance.
igmp-mld：interfacesこのサブツリーは、MLDインスタンスのインターフェースグローバルレベルでMLD属性の構成を指定します。構成を変更すると、MLDインスタンスのすべてのインターフェースでMLDメンバーシップが削除または再構築される可能性があります。
igmp-mld:interfaces/interface This subtree specifies the configuration for the MLD attributes at the interface level on a device. Modifying the configuration can cause MLD membership to be deleted or reconstructed on a specific interface of an MLD instance.
igmp-mld：interfaces / interfaceこのサブツリーは、デバイスのインターフェースレベルでMLD属性の構成を指定します。構成を変更すると、MLDインスタンスの特定のインターフェースでMLDメンバーシップが削除または再構築される可能性があります。
Unauthorized access to any data node of these subtrees can adversely affect the membership records of multicast routing subsystem on the local device. This may lead to network malfunctions, delivery of packets to inappropriate destinations, and other problems.
これらのサブツリーのデータノードへの不正アクセスは、ローカルデバイス上のマルチキャストルーティングサブシステムのメンバーシップレコードに悪影響を及ぼす可能性があります。これにより、ネットワークの誤動作、不適切な宛先へのパケットの配信、その他の問題が発生する可能性があります。
Some of the readable data nodes in this 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. These are the subtrees and data nodes and their sensitivity/vulnerability:
このYANGモジュールの一部の読み取り可能なデータノードは、一部のネットワーク環境では機密または脆弱である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を制御することが重要です（たとえば、get、get-config、または通知を介して）。これらは、サブツリーとデータノード、およびそれらの機密性/脆弱性です。
/rt:routing/rt:control-plane-protocols
/rt:control-plane-protocol/igmmp-mld:igmp
/rt:routing/rt:control-plane-protocols
/rt:control-plane-protocol/igmp-mld:mld
Unauthorized access to any data node of the above subtree can disclose the operational state information of IGMP or MLD on this device.
上記のサブツリーのデータノードへの不正アクセスは、このデバイス上のIGMPまたはMLDの動作状態情報を開示する可能性があります。
Some of the action operations in this YANG module may be considered sensitive or vulnerable in some network environments. It is thus important to control access to these operations. These are the operations and their sensitivity/vulnerability:
このYANGモジュールのアクション操作の一部は、一部のネットワーク環境では機密または脆弱であると見なされる場合があります。したがって、これらの操作へのアクセスを制御することが重要です。これらは操作とその感度/脆弱性です：
/rt:routing/rt:control-plane-protocols
/rt:control-plane-protocol/igmmp-mld:igmp/igmmp-mld:clear-groups
/rt:routing/rt:control-plane-protocols
/rt:control-plane-protocol/igmp-mld:mld/igmp-mld:clear-groups
Unauthorized access to any of the above action operations can delete the IGMP or MLD membership records on this device.
上記のアクション操作のいずれかに不正にアクセスすると、このデバイスのIGMPまたはMLDメンバーシップレコードが削除される可能性があります。
