DC ファブリックトポロジにおける EVPN 基本構成
次のものでFigure 1構成される完全なトポロジーが含まれています。
データセンターファブリック:
5つの EVPN リーフ Pe: リーフ-1、リーフ-2、リーフ-3、リーフ-4、およびリーフ-5
2つの EVPN 境界リーフ Pe があります。BL-1 および BL-2
2つのリーンスパインデバイス: スパイン1およびスパイン-2
外部マルチキャストの世界:
1つの PIM ゲートウェイ: PIM GW
1つの PIM RP: PIM-RP
エンドホストのマルチホーム向けの3台の CE デバイス: CE-1、CE、CE-3。
8個のルーターテスター (RT) ポートにより、マルチキャストトラフィック送信元と受信者をシミュレートできます。
これらのデバイスは必要に応じて構成します。
