2. Design of the Data Model
2. データモデルの設計
2.1. Scope of Model
2.1. モデルの範囲

The model covers MSDP [RFC3618].

モデルはMSDP [RFC3618]をカバーしています。

This model can be used to configure and manage MSDP protocol operations. 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 mechanisms, as 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、MSDPプロトコル操作を構成および管理するために使用できます。運用状態データと統計はこのモデルによって取得できます。このモデルでプロトコル固有の通知が定義されていなくても、[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は、このモデルのデータノード上の通知を購読するためにユーザーによって実装できます。

The model contains all the basic configuration parameters to operate the protocol. 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. This model can be extended, and it has been structured in a way that such extensions can be conveniently made.

このモデルには、プロトコルを操作するためのすべての基本構成パラメータが含まれています。実装の選択に応じて、いくつかのシステムがいくつかの高度なパラメータを設定可能にすることはできません。時折実装されたパラメータは、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。このモデルは延長することができ、そのような拡張を便利にすることができるように構成されています。

2.2. Specification
2.2. 仕様

The configuration data nodes cover global configuration attributes and per-peer configuration attributes. The state data nodes include global, per-peer, and SA information. The container "msdp" is the top-level container in this data model. The presence of this container is expected to enable MSDP protocol functionality. No notification is defined in this model.

構成データノードは、グローバル構成属性とピアごとの設定属性をカバーします。状態データノードは、グローバル、ピアごと、およびSA情報を含む。コンテナ「MSDP」は、このデータモデルの最上位コンテナです。このコンテナの存在は、MSDPプロトコル機能を有効にすると予想されます。このモデルでは通知は定義されていません。

3. Module Structure
3. モジュール構造

This model imports and augments the "ietf-routing" YANG data model defined in [RFC8349]. Both configuration data nodes and state data nodes as mentioned in [RFC8349] are augmented.

このモデルは、[RFC8349]で定義されている「IETF-routing」Yangデータモデルをインポートおよび増強します。[RFC8349]で述べた構成データノードと状態データノードは両方とも拡張されています。

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].

この文書で定義されている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。運用状態データは、同じ階層[RFC8407]内の関連する設定データと組み合わされます。

3.1. MSDP Configuration
3.1. MSDP設定

MSDP operation requires configuration information that is distributed amongst several peers. Several peers may be configured in a mesh-group. The SA information may be filtered by peers.

MSDP操作には、いくつかのピアの間で配布されている構成情報が必要です。いくつかのピアはメッシュグループで構成できます。SA情報はピアによってフィルタリングされてもよい。

The configuration modeling branch is composed of MSDP global and peer configurations. These two parts are the most important parts of MSDP.

構成モデリングブランチは、MSDPグローバルとピア構成で構成されています。これら2つの部分はMSDPの最も重要な部分です。

Besides the fundamental features of MSDP, several optional features are included in the model. These features help the control of MSDP. The peer features and SA features make the deployment and control easier. The connection parameters can be used to control the TCP connection because MSDP is based on TCP. The authentication features make the protocol more secure. The filter features selectively allow operators to prevent SA information from being forwarded to peers.

MSDPの基本的な機能に加えて、モデルにはいくつかのオプション機能が含まれています。これらの機能はMSDPの制御を助けます。ピア機能とSAの機能により、展開と制御が簡単になります。MSDPはTCPに基づくため、接続パラメータを使用してTCP接続を制御できます。認証機能により、プロトコルをより安全にします。フィルタ機能により、演算子がSA情報がピアに転送されるのを防ぐことができます。

3.2. MSDP States
3.2. MSDPの状態

MSDP states are composed of the MSDP global state, the MSDP peer state, statistics information, and SA cache information. The statistics information and SA cache information help the operator retrieve data regarding the protocol's condition.

MSDP状態は、MSDPグローバル状態、MSDPピア状態、統計情報、およびSAキャッシュ情報で構成されています。統計情報とSAキャッシュ情報は、オペレータがプロトコルの状態に関するデータを取得するのに役立ちます。

YANG actions are defined to clear the connection of one specific MSDP peer, clear the connections of all MSDP peers, or clear some or all of the SA caches.

Yangのアクションは、特定のMSDPピアの接続をクリアし、すべてのMSDPピアの接続をクリアするか、SAキャッシュの一部または全部を消去するように定義されています。

5. Security Considerations
5. セキュリティに関する考慮事項

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]または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ているデータのスキーマを定義しています。最低のNetConfレイヤーはセキュアトランスポート層で、必須の実装セキュアトランスポートはSecure Shell(SSH)[RFC6242]です。最低のRETCONFレイヤーはhttpsで、必須のセキュアトランスポートは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ユーザへのアクセスを制限する手段を、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設定されたサブセットに制限することを可能にします。

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モジュールで定義されているデータノードは、書き込み可能/作成可能/削除可能な(すなわち、デフォルトであるConfig True)。これらのデータノードは、一部のネットワーク環境では敏感または脆弱と見なすことができます。適切な保護なしにこれらのデータノードへの書き込み操作(例えば、edit-config)は、ネットワーク操作に悪影響を及ぼす可能性があります。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。

Under /rt:routing/rt:control-plane-protocols/msdp:

/ RT:ルーティング/ RT:Control-Plane-Protocols / MSDP:

msdp:global

MSDP:Global.

This subtree specifies the configuration for the MSDP attributes at the global level. Modifying the configuration can cause MSDP default peers to be deleted or the connection to be rebuilt and can also cause unexpected filtering of the SA.

このサブツリーは、グローバルレベルでのMSDP属性の設定を指定します。構成を変更すると、MSDPのデフォルトピアを削除するか、接続を再構築することもでき、SAの予期せぬフィルタリングを引き起こす可能性があります。

msdp:peers

MSDP:ピアー

This subtree specifies the configuration for the MSDP attributes at the peer level. Modifying the configuration will allow unexpected MSDP peer establishment and unexpected SA information learning and advertisement.

このサブツリーは、ピアレベルのMSDP属性の設定を指定します。構成を変更すると、予期しないMSDPピア設立と予期しないSA情報学習と広告が可能になります。

The writability of the "key" field should be strictly controlled. Misoperation of the key will break the existing MSDP connection, and the associated SA caches will also be deleted.

「キー」フィールドの書き込み可能性は厳密に制御されるべきです。キーの誤操作は既存のMSDP接続を分割し、関連するSAキャッシュも削除されます。

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モジュールの読み取り可能なデータノードのいくつかは、いくつかのネットワーク環境では敏感または脆弱と見なされ得る。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(例えば、get、get - config、または通知)を制御することが重要である。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。

/rt:routing/rt:control-plane-protocols/msdp:

/ RT:ルーティング/ RT:Control-Plane-Protocols / MSDP:

Unauthorized access to any data node of the above subtree can disclose the operational state information of MSDP on this device. For example, disclosure of the peer information may lead to a forged connection attack, and uncorrected modification of the ACL nodes may lead to filter errors.

上記のサブツリーの任意のデータノードへの不正アクセスは、この装置上のMSDPの動作状態情報を開示することができる。例えば、ピア情報の開示は鍛造接続攻撃につながり、ACLノードの修正されていない修正はフィルタエラーをもたらし得る。

The "key" field is also a sensitive readable configuration. Unauthorized reading of this field may lead to leaking of the password. Modification will allow the unexpected rebuilding of connected peers.

「鍵」フィールドも機密可読設定です。このフィールドの不正な読み取りは、パスワードの漏洩につながる可能性があります。変更は、接続されているピアの予期しない再構築を可能にします。

Authentication configuration is supported via the specification of key-chains [RFC8177] or the direct specification of the key and the authentication algorithm. Hence, authentication configuration in the "authentication" container inherits the security considerations discussed in [RFC8177]. This includes the considerations with respect to the local storage and handling of authentication keys.

認証設定は、キーチェーン[RFC8177]の仕様またはキーの直接指定と認証アルゴリズムを介してサポートされています。したがって、「認証」コンテナの認証構成は、[RFC8177]で説明したセキュリティ上の考慮事項を継承します。これには、認証キーのローカルストレージと処理に関する考慮事項が含まれます。

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RPC操作のいくつかは、一部のネットワーク環境では敏感または脆弱と見なすことができます。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/msdp:clear-peer
        
   /rt:routing/rt:control-plane-protocols/msdp:clear-sa-cache
        

Unauthorized access to either of the above action operations can lead to rebuilding of the MSDP peers' connections or deletion of SA records on this device.

上記の操作操作のいずれかへの不正アクセスは、MSDPピアの接続またはこのデバイスのSAレコードの削除の再構築につながる可能性があります。
