例:IS-IS 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、IS-ISプロトコルにバックアップ選択ポリシーを設定する方法を示しています。
バックアップ選択ポリシーを有効にすると、Junos OSで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、ネイバー、ネイバータグです。
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 シリーズ 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、T シリーズ コア ルーターの組み合わせが可能な 8 台のルーター
すべてのデバイスでJunos OSリリース14.1以降が実行されている
開始する前に、以下を行います。
デバイス インターフェイスを設定します。
IS-ISを設定します。
概要
Junos OSリリース14.1以降、デフォルトループフリー代替(LFA)選択アルゴリズムまたは基準は、LFAポリシーで上書きできます。これらのポリシーは、各宛先(IPv4およびIPv6)とプライマリネクストホップインターフェイスに対して設定されます。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者グループ、srlg、帯域幅、保護タイプ、メトリック、ネイバー、ネイバータグ属性に基づいてLFA選択を適用します。バックアップ最短パスファースト(SPF)計算時に、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によって蓄積されます。IGPによって内部で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およびIPv6)とプライマリネクストホップインターフェイスに対して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、 階層レベルで 設定ステートメントを[edit routing-options]含backup-selectionめます。コマンドはshow backup-selection、特定のインターフェイスと宛先に設定されたポリシーを表示します。ディスプレイは、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。
トポロジ
このトポロジーでは、デバイスR3にバックアップ選択ポリシーが設定されています。
