例:トランスポートクラストンネルを介したEVPN-VPWSの設定
概要
この例では、基本的なネットワークトポロジーを使用して、PE1とPE2の間の2つのRSVP-TEトランスポートクラストンネル上にEVPN-VPWSを設定します。2 つのトランスポートクラスを定義し、トランスポートクラスに異なるトンネルを割り当てます。以下の機能でデバイスを構成します。
-
EVPN-VPWS ルーティング インスタンス。
-
MPLS、LSP、およびBGPを使用したRSVP-TEトンネル。
-
ゴールドとブロンズのトランスポートクラス。
-
ゴールドとブロンズのトランスポートクラスに個別のコミュニティを指定するポリシーフィルター。
必要条件
-
PEルーターとして設定された2台のMXシリーズルーター
-
ルートリフレクタとして設定された1台のMXシリーズルーター
-
すべてのデバイスで実行されているJunos OS リリース 23.1R1 以降。
位相幾何学
図 1 は、2 つの PE デバイスと、PE デバイス間のルートを転送するルート リフレクタを使用した基本的なトポロジーを示しています。CE デバイスのペアは、それぞれ PE1 と PE2 に接続されています。PE1とPE2は、CE1とCE2からのトラフィックをゴールドトンネル経由でルーティングし、CE3とCE4からのトラフィックをブロンズトンネル経由でルーティングします。
