This document introduces a YANG [RFC7950] data model for the Routing Information Protocol (RIP) [RFC2453][RFC2080]. RIP was designed to work as an Interior Gateway Protocol (IGP) in moderate-size Autonomous Systems (AS).
このドキュメントでは、ルーティング情報プロトコル（RIP）[RFC2453] [RFC2080]のYANG [RFC7950]データモデルを紹介します。 RIPは、中規模の自律システム（AS）でInterior Gateway Protocol（IGP）として機能するように設計されています。
This YANG data model supports both RIP version 2 and RIPng. RIP version 2 (defined in [RFC2453]) supports IPv4. RIPng (defined in [RFC2080]) supports IPv6.
このYANGデータモデルは、RIPバージョン2とRIPngの両方をサポートしています。 RIPバージョン2（[RFC2453]で定義）はIPv4をサポートしています。 RIPng（[RFC2080]で定義）はIPv6をサポートしています。
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 following terms are defined in [RFC7950] and are not redefined here:
以下の用語は[RFC7950]で定義されており、ここでは再定義されません。
* augment
* 増強
* data model
* データ・モデル
* data node
* データノード
A simplified graphical representation of the data model is used in this document. The meaning of the symbols in these diagrams is defined in [RFC8340].
このドキュメントでは、データモデルの簡略化されたグラフィカル表現を使用しています。これらの図の記号の意味は、[RFC8340]で定義されています。
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.
このドキュメントでは、データノード、アクション、およびその他のデータモデルオブジェクトの名前は、YANGモジュールの各名前が定義されているコンテキストから明らかである限り、プレフィックスなしで使用されることがよくあります。それ以外の場合、表1に示すように、対応するYANGモジュールに関連付けられた標準の接頭辞を使用して名前に接頭辞が付けられます。

The data model covers RIP version 2 [RFC2453] and RIPng [RFC2080] protocols. The model is designed to be implemented on a device where RIP version 2 or RIPng is implemented, and can be used to:
データモデルは、RIPバージョン2 [RFC2453]およびRIPng [RFC2080]プロトコルをカバーしています。このモデルは、RIPバージョン2またはRIPngが実装されているデバイスに実装されるように設計されており、次の目的で使用できます。
* Configure the RIP version 2 or RIPng protocol.
* RIPバージョン2またはRIPngプロトコルを構成します。
* Manage the protocol operational behaviors.
* プロトコルの動作動作を管理します。
* Retrieve the protocol operational status.
* プロトコルの動作ステータスを取得します。
The capabilities described in [RFC1724] are covered.
[RFC1724]で説明されている機能がカバーされています。
This data model augments the core routing data model "ietf-routing" specified in [RFC8349].
このデータモデルは、[RFC8349]で指定されているコアルーティングデータモデル「ietf-routing」を補強します。
+--rw routing
+--rw router-id?
+--rw control-plane-protocols
| +--rw control-plane-protocol* [type name]
| +--rw type
| +--rw name
| +--rw rip <= Augmented by this Model
...
The "rip" container instantiates a RIP entity that supports RIP version 2 or RIPng. Depending on the implementation of "ietf-routing", a RIP instance MAY belong to a logical router or network instance.
「rip」コンテナは、RIPバージョン2またはRIPngをサポートするRIPエンティティをインスタンス化します。 「ietf-routing」の実装に応じて、RIPインスタンスは論理ルーターまたはネットワークインスタンスに属してもよい（MAY）。
The data model structure for the protocol configuration is as shown below:
プロトコル構成のデータモデル構造は次のとおりです。
augment /rt:routing/rt:control-plane-protocols/
rt:control-plane-protocol:
+--rw rip
+--rw <per instance configuration>
+--rw interface* [interface]
+--rw interface if:interface-ref
+--rw <per interface configuration>
+--rw neighbors {explicit-neighbors}?
| +--rw neighbor* [address]
| +--rw address inet:ip-address
| +--rw <per neighbor configuration>
The data model allows the configuration of the following protocol entities:
データモデルでは、次のプロトコルエンティティを構成できます。
* Protocol instance (RIP version 2 or RIPng)
* プロトコルインスタンス（RIPバージョン2またはRIPng）
* Interface
* インターフェース
* Neighbor
* 隣人
The data model structure for the protocol states is as shown below:
プロトコル状態のデータモデル構造は次のとおりです。
augment /rt:routing/rt:control-plane-protocols/
rt:control-plane-protocol:
+--rw rip
+--ro <per instance operational states>
+--rw interface* [interface]
| +--rw interface if:interface-ref
| +--ro <per instance operational states>
| +--ro statistics {interface-statistics}?
| +--ro <per instance statistics>
+--ro ipv4
| +--ro neighbors
| | +--ro neighbor* [ipv4-address]
| | +--ro <per neighbor IPv4 operational states>
| +--ro routes
| +--ro route* [ipv4-prefix]
| +--ro <IPv4 RIP route states>
+--ro ipv6
| +--ro neighbors
| | +--ro neighbor* [ipv6-address]
| | +--ro <per neighbor IPv6 operational states>
| +--ro routes
| +--ro route* [ipv6-prefix]
| +--ro ipv6-prefix inet:ipv6-prefix
| +--ro <IPv4 RIP route states>
+--ro statistics {global-statistics}?
+--ro <per instance statistics>
This model 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]. When protocol states are retrieved from the NMDA operational state datastore, the returned states cover all "config true" (rw) and "config false" (ro) nodes defined in the schema.
このモデルは、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]。プロトコル状態がNMDA動作状態データストアから取得される場合、返される状態は、スキーマで定義されているすべての「config true」（rw）および「config false」（ro）ノードをカバーします。
The model allows the retrieval of protocol states at the following levels:
このモデルでは、次のレベルでプロトコルの状態を取得できます。
* Protocol instance (RIP version 2 or RIPng)
* プロトコルインスタンス（RIPバージョン2またはRIPng）
* Interface
* インターフェース
* Neighbor
* 隣人
* Route
* ルート
This model defines one RPC "clear-rip-route" that can be used to clear RIP routes from the routing table.
このモデルは、ルーティングテーブルからRIPルートをクリアするために使用できる1つのRPC "clear-rip-route"を定義します。
This model does not define RIP-specific notifications. To enable notifications, the mechanisms defined in [RFC8639] and [RFC8641] can be used. This mechanism currently allows the user to do the following:
このモデルでは、RIP固有の通知は定義されていません。通知を有効にするには、[RFC8639]と[RFC8641]で定義されているメカニズムを使用できます。このメカニズムでは現在、ユーザーは次のことを実行できます。
* Subscribe to notifications on a per-client basis.
* クライアントごとに通知をサブスクライブします。
* Specify subtree filters or XML Path Language (XPath) filters so that only interested contents will be sent.
* 関係のあるコンテンツのみが送信されるように、サブツリーフィルターまたはXMLパス言語（XPath）フィルターを指定します。
* Specify either periodic or on-demand notifications.
* 定期的またはオンデマンドの通知を指定します。
This model defines several features that are beyond the basic RIP configuration, and it is the responsibility of each vendor to decide whether to support a given feature on a device.
このモデルは、基本的なRIP構成を超えるいくつかの機能を定義します。デバイスで特定の機能をサポートするかどうかを決定するのは、各ベンダーの責任です。
This document defines the YANG module "ietf-rip", which has the following tree structure:

This document registers the following YANG modules 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]に次のYANGモジュールを登録しています。
Name: ietf-rip
Namespace: urn:ietf:params:xml:ns:yang:ietf-rip
Prefix: rip
Reference: RFC 8695
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 NETCONF 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.
NETCONF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済み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。
/rt:routing/rt:control-plane-protocols/rt:control-plane-protocol/
rip:rip
Unauthorized access to any data node of these subtrees can adversely affect the routing subsystem of both the local device and the network. 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、ローカルデバイスとネットワークの両方のルーティングサブシステム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/
rip:rip
Unauthorized access to any data node of these subtrees can disclose the operational state information of RIP on this device.
これらのサブツリーのデータノードへの不正アクセスにより、このデバイス上のRIPの動作状態情報が開示される可能性があります。
Some of the RPC 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モジュールの一部のRPC操作は、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：
RPC clear-rip-route:
RPCクリアリップルート：
Unauthorized access to the RPC above can adversely affect the routing subsystem of both the local device and the network. This may lead to network malfunctions, delivery of packets to inappropriate destinations, and other problems.
上記のRPCへの不正アクセスは、ローカルデバイスとネットワークの両方のルーティングサブシステム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。
