例:シングルホームEVPNによるPBBの設定
この例では、プロバイダバックボーンブリッジング(PBB)とイーサネットVPN(EVPN)を統合する方法を示しています。この統合により、コアでのコントロールプレーン運用が簡素化され、通常のEVPNよりも迅速なコンバージェンスと拡張性の強化が可能になります。PBB-EVPNアプリケーションには、データセンターの相互接続(DCI)およびキャリアイーサネットE-LANサービスが含まれます。
要件
この例では、以下のハードウェアおよびソフトウェアコンポーネントを使用しています。
3台のPE(プロバイダ エッジ)デバイスがそれぞれ、シングルホームの顧客サイトに接続されます。
PE デバイスにシングルホーム接続されている 4 台のカスタマー エッジ(CE)デバイス。
すべての PE ルーターで実行されている Junos OS リリース 17.2R1 以降。
始める前に:
デバイスインターフェイスを設定します。
すべての PE デバイスで OSPF などの IGP を設定します。
PEデバイス間に内部BGPセッションを確立します。
PE デバイスで RSVP を有効にします。
PE デバイス間の MPLS およびラベルスイッチパス(LSP)を設定します。
概要とトポロジー
PBBとEVPNの統合機能の導入により、PBBはイーサネットVPN(EVPN)と統合され、コア全体のコントロールプレーン学習を大幅に削減し、データセンター接続など、膨大な数のレイヤー2サービスが簡略化された方法でネットワークを通過できるようになりました。PBBとEVPNの統合機能のプラットフォームおよびソフトウェアリリースサポートについては、機能エクスプローラーのPBBとEVPNの統合のエントリーを参照してください。
PBB-EVPNネットワークでは、PBBコアのバックボーンコアブリッジ(BCB)デバイスがMPLSに置き換えられますが、PBBバックボーンエッジブリッジ(BEB)のサービス拡張プロパティは保持されます。Bコンポーネント(プロバイダルーティングインスタンス)は、EVPN BGPシグナリングを使用してシグナリングされ、プロバイダエッジ(PE)とプロバイダ(P)デバイスを使用してMPLS内にカプセル化されます。このように、PBB-EVPNは、PBBの膨大な拡張性と従来の基本的なMPLSコアネットワークのシンプルさを組み合わせており、通常のPBBと比較して、ネットワーク全体の状態情報量を大幅に削減します。
