概要

この記事では、クライアントとレイヤ 2 トンネリング プロトコル アクセス コンセントレータ（LNS）間にバーチャル プライベート ダイヤルアップ ネットワーク（VPDN）を介してマルチリンク ポイントツーポイント プロトコル（MLPPP）セッションを確立するのに役立つ、クライアント、LAC およびレイヤ２ トンネリング プロトコル ネットワークサーバ（LNA）の構成について説明します。

前提条件

要件

この設定を行う前に、以下の要件を満たしていることを確認してください。

- エンドツーエンドのレイヤ 1 接続が有効

使用するコンポーネント

このドキュメントの内容は、特定のソフトウェアやハードウェアのバージョンに限定されるものではありません。

このドキュメントの情報は、特定のラボ環境にあるデバイスに基づいて作成されました。このドキュメントで使用するすべてのデバイスは、初期（デフォルト）設定の状態から起動しています。対象のネットワークが実稼働中である場合には、どのようなコマンドについても、その潜在的な影響について確実に理解しておく必要があります。

ネットワーク図

設定

注：PPP またはマルチリンク PPP セッションの開始時における PPP 制御パケット交換の際には、マルチリンク PPP セッションは、CPE と LNS との間（LAC との間ではなく）でネゴシエートされます。LAC は、マルチリンク PPP セッションについて認識しません。そのため、CPE が PPP-LCP セッションを開始すると、LCP ネゴシエーションの一部として含まれるマルチリンク（Maximum Receive Reconstructed Unit（MRRU））ネゴシエーションは、LAC が LNS との接続をまだ確立していない場合（通常は確立していません）に失敗することがあります。 LAC と LNS 間で IP 到達可能性が確立されると、LNS は CPE とマルチリンク（MRRU）LCP オプションを再ネゴシエートし、2 つのピア デバイスがエンドツーエンドのマルチリンク PPP セッションを確立できるようになります。
