簡介
本檔案介紹如何驗證作為軟體定義存取(SDA)一部分的北南流量。
必要條件
需求
思科建議您瞭解以下主題：
- IP轉送
- 邊界閘道通訊協定(BGP)
- 軟體定義存取(SD-Access)
採用元件

背景資訊
SDA南北流量是指存在於SDA交換矩陣內並且希望與不在SDA交換矩陣內的終端或伺服器通訊的概念。
- 首先，終端為其預設網關（交換矩陣邊緣節點）解析ARP
- 然後終端將IP資料包傳送到預設網關，即交換矩陣邊緣節點上的任播網關。
- 交換矩陣邊緣節點使用思科快速轉發(CEF)將資料包傳送出去，哪個位置ID分隔協定(LISP)驅動CEF。
- 交換矩陣邊緣節點具有用於0.0.0.0/0的預設路由的對映快取條目，操作是封裝通向代理出口隧道路由器(PETR)或SDA交換矩陣邊界節點的所有資料包。
- 交換矩陣邊緣節點將原始IP資料包封裝到VXLAN中，並將資料包轉發到SDA交換矩陣邊界節點。
- 邊界節點對資料包解除封裝，並針對原始資料包目標IP地址執行IP查詢，然後將資料包轉發到適當的下一跳，而下一跳很可能是不屬於SDA交換矩陣的上游Fusion路由器。
- 接下來，對於返回到SDA交換矩陣內端點的流量，Fusion路由器會收到該資料包，並且還會對目標IP地址執行IP查詢並將其轉發到適當的下一跳（即邊界節點）。
- 交換矩陣邊界節點會諮詢從LISP派生的CEF，以確定哪個交換矩陣邊緣節點與端點關聯並將原始資料包封裝到VXLAN中並傳送出去。
- 交換矩陣邊緣將資料包解除封裝，並將原始資料包轉發到終端。
基本工作流程
參考拓撲
在本示例中，C9000v交換機用作交換矩陣邊緣和並置邊界。Fusion路由器和Internet路由器是CSR1Kv路由器。位於10.47.4.2（位於VLAN 1026中）的終端和red_vn虛擬網路(VN)的一部分正在嘗試ping 8.8.8.8,8.8作為Internet路由器上的Loopback0介面存在。
