例：OSPF または OSPF3 プロトコルのバックアップ選択ポリシーの設定
この例では、ネットワーク内のループフリーの代替(LFA)を選択できる、OSPF または OSPF3 プロトコルのバックアップ選択ポリシーを設定する方法を示します。
バックアップ選択ポリシーを有効にすると、Junos OSは、ネットワーク内のリンクとノードのポリシールールと属性に基づいてLFAを選択できます。これらの属性は、admin-group、srlg、帯域幅、保護タイプ、メトリック、およびノードです。
要件
この例では、以下のハードウェアとソフトウェアのコンポーネントを使用しています。
M Series マルチサービス エッジ ルーター、MX シリーズ 5G ユニバーサル ルーティング プラットフォーム、PTX シリーズ パケット トランスポート ルーター、T Series コア ルーターを組み合わせた 8 台のルーター
すべてのデバイスでJunos OS Release 15.1以降が作動していること
開始する前に、以下を実行します。
デバイスインターフェイスを設定します。
OSPFを設定します。
概要
Junos OS では、デフォルトのループフリーの代替(LFA)選択アルゴリズムや基準は、LFA ポリシーで上書きできます。これらのポリシーは、宛先(IPv4 および IPv6)およびプライマリ ネクストホップ インターフェイスごとに設定されます。これらのバックアップ ポリシーは、バックアップ パスの管理グループ、srlg、帯域幅、保護タイプ、メトリック、ノード属性に基づいて LFA の選択を強制します。バックアップ最短パスファースト(SPF)計算中に、バックアップネクストホップごとに保存されたバックアップパスの各属性(ノードとリンクの両方)がIGPによって累積されます。IGP によって内部的に作成されたルートでは、各バックアップ パスの属性セットが、各宛先(IPv4 と IPv6)およびプライマリ ネクストホップ インターフェイスに設定されたポリシーに対して評価されます。最初または最適なバックアップ パスが選択され、ルーティング テーブルのバックアップ ネクスト ホップとしてインストールされます。バックアップ選択ポリシーを設定するには、[edit routing-options]階層レベルで backup-selection 設定ステートメントを含めます。show backup-selection コマンドは、指定されたインターフェイスと宛先に対して設定されたポリシーを表示します。表示は、特定の宛先、プレフィックス、インターフェイス、または論理システムに対してフィルタリングできます。
設定
CLIクイック構成
この例を迅速に設定するには、以下のコマンドをコピーして、テキストファイルに貼り付け、改行を削除し、ネットワーク設定に一致させる必要がある詳細情報を変更し、コマンドを [edit] 階層レベルでCLIにコピーアンドペーストして、設定モードから commit を入力します。
