This document defines a YANG data model [RFC7950] for management of IP implementations.
このドキュメントは、IP実装の管理のためのYANGデータモデル[RFC7950]を定義します。
The data model covers configuration of per-interface IPv4 and IPv6 parameters as well as mappings of IP addresses to link-layer addresses. It also provides information about which IP addresses are operationally used and which link-layer mappings exist. Per-interface parameters are added through augmentation of the interface data model defined in [RFC8343].
データモデルは、インターフェイスごとのIPv4およびIPv6パラメータの構成、およびIPアドレスのリンク層アドレスへのマッピングをカバーしています。また、運用に使用されているIPアドレス、および存在するリンク層マッピングに関する情報も提供します。インターフェースごとのパラメーターは、[RFC8343]で定義されているインターフェースデータモデルの拡張を通じて追加されます。
This version of the IP data model supports the Network Management Datastore Architecture (NMDA) [RFC8342].
このバージョンのIP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]をサポートしています。
The "ipv4" and "ipv6" subtrees with "config false" data nodes in the "/interfaces-state/interface" subtree are deprecated. All "config false" data nodes are now present in the "ipv4" and "ipv6" subtrees in the "/interfaces/interface" subtree.
「/ interfaces-state / interface」サブツリーの「config false」データノードを持つ「ipv4」および「ipv6」サブツリーは非推奨になりました。すべての「config false」データノードは、「/ interfaces / interface」サブツリーの「ipv4」および「ipv6」サブツリーに存在します。
Servers that do not implement NMDA or that wish to support clients that do not implement NMDA MAY implement the deprecated "ipv4" and "ipv6" subtrees in the "/interfaces-state/interface" subtree.
NMDAを実装していないサーバー、またはNMDAを実装していないクライアントをサポートしたいサーバーは、「/ interfaces-state / interface」サブツリーに非推奨の「ipv4」および「ipv6」サブツリーを実装できます。
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.
キーワード「MUST」、「MUST NOT」、「REQUIRED」、「SHALL」、「SHALL NOT」、「SHOULD」、「SHOULD NOT」、「RECOMMENDED」、「NOT RECOMMENDED」、「MAY」、「OPTIONALこのドキュメントの「」は、BCP 14 [RFC2119] [RFC8174]で説明されているように解釈されます。

The terminology for describing YANG data models is found in [RFC7950].
YANGデータモデルを記述するための用語は、[RFC7950]にあります。
Tree diagrams used in this document follow the notation defined in [RFC8340].
このドキュメントで使用されるツリー図は、[RFC8340]で定義された表記に従います。
This document defines the YANG module "ietf-ip", which augments the "interface" lists defined in the "ietf-interfaces" module [RFC8343] with IP-specific data nodes.
このドキュメントは、Yangモジュール「ietf-ip」を定義します。これは、「ietf-interfaces」モジュール[RFC8343]で定義された「インターフェース」リストにIP固有のデータノードを追加します。
The data model has the following structure for IP data nodes per interface, excluding the deprecated data nodes:
データモデルは、非推奨のデータノードを除いて、インターフェイスごとのIPデータノードについて次の構造を持っています。
module: ietf-ip
augment /if:interfaces/if:interface:
+--rw ipv4!
| +--rw enabled? boolean

+--rw temporary-valid-lifetime? uint32
| {ipv6-privacy-autoconf}?
+--rw temporary-preferred-lifetime? uint32
{ipv6-privacy-autoconf}?
The data model defines two containers per interface -- "ipv4" and "ipv6", representing the IPv4 and IPv6 address families. In each container, there is a leaf "enabled" that controls whether or not the address family is enabled on that interface, and a leaf "forwarding" that controls whether or not IP packet forwarding for the address family is enabled on the interface. In each container, there is also a list of addresses and a list of mappings from IP addresses to link-layer addresses.
データモデルは、インターフェイスごとに2つのコンテナーを定義します。「ipv4」と「ipv6」は、IPv4およびIPv6アドレスファミリーを表します。各コンテナには、そのインターフェイスでアドレスファミリを有効にするかどうかを制御する「有効」リーフと、そのインターフェイスでアドレスファミリのIPパケット転送を有効にするかどうかを制御する「転送」リーフがあります。各コンテナには、アドレスのリストと、IPアドレスからリンク層アドレスへのマッピングのリストもあります。
If the device implements the IP-MIB [RFC4293], each entry in the "ipv4/address" and "ipv6/address" lists is mapped to one ipAddressEntry, where the ipAddressIfIndex refers to the "address" entry's interface.
デバイスがIP-MIB [RFC4293]を実装している場合、「ipv4 / address」および「ipv6 / address」リストの各エントリは1つのipAddressEntryにマッピングされます。ipAddressIfIndexは「address」エントリのインターフェースを指します。
The IP-MIB defines objects to control IPv6 Router Advertisement messages. The corresponding YANG data nodes are defined in [RFC8022].
IP-MIBは、IPv6ルーターアドバタイズメッセージを制御するオブジェクトを定義します。対応するYANGデータノードは[RFC8022]で定義されています。
The entries in "ipv4/neighbor" and "ipv6/neighbor" are mapped to ipNetToPhysicalTable.
「ipv4 / neighbor」と「ipv6 / neighbor」のエントリは、ipNetToPhysicalTableにマッピングされます。
The following table lists the YANG data nodes with corresponding objects in the IP-MIB.
次の表に、IP-MIB内の対応するオブジェクトを含むYANGデータノードを示します。

This document registers a YANG module in the "YANG Module Names" registry [RFC6020].
このドキュメントでは、「YANGモジュール名」レジストリ[RFC6020]にYANGモジュールを登録しています。
Name: ietf-ip
Namespace: urn:ietf:params:xml:ns:yang:ietf-ip
Prefix: ip
Reference: RFC 8344
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 [RFC5246].
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。最下位のNETCONFレイヤーはセキュアなトランスポートレイヤーであり、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）です[RFC6242]。最も低いRESTCONF層はHTTPSであり、実装に必須のセキュアなトランスポートはTLS [RFC5246]です。
The NETCONF access control model [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.
NETCONFアクセス制御モデル[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、書き込み可能/作成可能/削除可能なデータノードが多数定義されています（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。
ipv4/enabled and ipv6/enabled: These leafs are used to enable or disable IPv4 and IPv6 on a specific interface. By enabling a protocol on an interface, an attacker might be able to create an unsecured path into a node (or through it if routing is also enabled). By disabling a protocol on an interface, an attacker might be able to force packets to be routed through some other interface or deny access to some or all of the network via that protocol.
ipv4 / enabledおよびipv6 / enabled：これらのリーフは、特定のインターフェースでIPv4およびIPv6を有効または無効にするために使用されます。インターフェースでプロトコルを有効にすることにより、攻撃者はノードへの（またはルーティングも有効になっている場合はそれを介して）安全でないパスを作成できる可能性があります。攻撃者は、インターフェイス上のプロトコルを無効にすることにより、パケットを他のインターフェイス経由で強制的にルーティングしたり、そのプロトコルを介したネットワークの一部またはすべてへのアクセスを拒否したりすることができます。
ipv4/address and ipv6/address: These lists specify the configured IP addresses on an interface. By modifying this information, an attacker can cause a node to either ignore messages destined to it or accept (at least at the IP layer) messages it would otherwise ignore. The use of filtering or security associations may reduce the potential damage in the latter case.
ipv4 / addressおよびipv6 / address：これらのリストは、インターフェースに構成されたIPアドレスを指定します。この情報を変更することにより、攻撃者はノードに宛てられたメッセージを無視するか、そうでなければ無視するメッセージを（少なくともIP層で）受け入れることができます。フィルタリングまたはセキュリティアソシエーションを使用すると、後者の場合の潜在的な損傷を減らすことができます。
ipv4/forwarding and ipv6/forwarding: These leafs allow a client to enable or disable the forwarding functions on the entity. By disabling the forwarding functions, an attacker would possibly be able to deny service to users. By enabling the forwarding functions, an attacker could open a conduit into an area. This might result in the area providing transit for packets it shouldn't, or it might allow the attacker access to the area, bypassing security safeguards.
ipv4 / forwardingおよびipv6 / forwarding：これらのリーフにより、クライアントはエンティティの転送機能を有効または無効にできます。転送機能を無効にすることにより、攻撃者はユーザーへのサービスを拒否できる可能性があります。転送機能を有効にすることにより、攻撃者はエリアへのコンジットを開く可能性があります。これにより、エリアでパケットの通過が許可されない可能性があります。または、セキュリティ保護機能をバイパスして、エリアへの攻撃者のアクセスを許可する可能性があります。
ipv6/autoconf: The leafs in this branch control the autoconfiguration of IPv6 addresses and, in particular, whether or not temporary addresses are used. By modifying the corresponding leafs, an attacker might impact the addresses used by a node and -- thus, indirectly -- the privacy of the users using the node.
ipv6 / autoconf：このブランチのリーフは、IPv6アドレスの自動構成を制御し、特に一時アドレスが使用されるかどうかを制御します。攻撃者は、対応するリーフを変更することにより、ノードが使用するアドレスに影響を与える可能性があり、間接的に、ノードを使用するユーザーのプライバシーに影響を与える可能性があります。
ipv4/mtu and ipv6/mtu: Setting these leafs to very small values can be used to slow down interfaces.
ipv4 / mtuおよびipv6 / mtu：これらの葉を非常に小さな値に設定すると、インターフェースの速度を低下させることができます。

Appendix B. Example: NETCONF <get-data> Reply
This section gives an example of a reply to the NETCONF <get-data> request for the operational state datastore for a device that implements the data model defined in this document.
このセクションでは、このドキュメントで定義されているデータモデルを実装するデバイスの動作状態データストアのNETCONF <get-data>要求に対する応答の例を示します。
This example uses the "origin" annotation, which is defined in the module "ietf-origin" [RFC8342].
この例では、モジュール「ietf-origin」[RFC8342]で定義されている「origin」アノテーションを使用しています。
