バックグラウンド情報
SDAのノースサウス(North-South)トラフィックフローは、SDAファブリック内に存在し、SDAファブリック内にないエンドポイントまたはサーバと通信することを望むエンドポイントの概念を指します。
- 最初に、エンドポイントはデフォルトゲートウェイ（ファブリックエッジノード）のARPを解決します
- 次に、エンドポイントはIPパケットをデフォルトゲートウェイ（ファブリックエッジノード上のエニーキャストゲートウェイ）に送信します。
- ファブリックエッジノードはCisco Express Forwarding(CEF)を使用してパケットを送信し、Locator ID Separator Protocol(LISP)がCEFを駆動します。
- ファブリックエッジノードには0.0.0.0/0のデフォルトルートのマップキャッシュエントリがあり、アクションはプロキシ出力トンネルルータ(PETR)またはSDAファブリック境界ノードに向かうすべてのパケットをカプセル化することです。
- ファブリックエッジノードは、元のIPパケットをVXLANにカプセル化し、SDAファブリック境界ノードにパケットを転送します。
- ボーダーノードはパケットをカプセル化解除し、元のパケットの宛先IPアドレスに対してIPルックアップを実行し、適切なネクストホップにパケットを転送します。このネクストホップは、おそらくSDAファブリックの一部ではないアップストリームFusionルータです。
- 次に、SDAファブリック内のエンドポイントに戻るリターントラフィックの場合、パケットはFusionルータによって受信され、宛先IPアドレスに対してIPルックアップも実行されて、適切なネクストホップ（境界ノード）に転送されます。
- ファブリックボーダーノードは、LISPから派生したCEFを参照して、エンドポイントに関連付けられているファブリックエッジノードを判別し、元のパケットをVXLANでカプセル化して送信します。
- ファブリックエッジはパケットのカプセルを解除し、元のパケットをエンドポイントに転送します。
基本ワークフロー
参照トポロジ
この例では、C9000vスイッチはファブリックエッジおよびコロケート境界として機能します。FusionルータとインターネットルータはCSR1Kvルータです。VLAN 1026にあり、red_vn仮想ネットワーク(VN)の一部である10.47.4.2のエンドポイントが、インターネットルータのLoopback0インターフェイスとして存在する8.8.8.8へのpingを試みています。
