Resolución de Problemas de SDA Forwarding North-South Traffic Flow
Contenido
Introducción
Este documento describe cómo validar el flujo de tráfico Norte-Sur como parte del acceso definido por software (SDA).
Prerequisites

Antecedentes
El flujo de tráfico SDA Norte-Sur hace referencia al concepto en el que un terminal que existe dentro del fabric SDA y desea comunicarse con un terminal o servidor que no se encuentra dentro del fabric SDA.
- En primer lugar, el terminal resuelve el ARP para su gateway predeterminada, que es el nodo de Fabric Edge
- A continuación, el terminal envía el paquete IP hacia el gateway predeterminado, que es Anycast Gateway en el nodo de Fabric Edge.
- El nodo de Fabric Edge utiliza Cisco Express Forwarding (CEF) para enviar el paquete, que es el protocolo LISP (del inglés Locator ID Separator Protocol, protocolo de separación de ID de localizador) que controla CEF.
- El nodo de borde del fabric tiene una entrada de caché de mapas para 0.0.0.0/0, ruta predeterminada y la acción es encapsular todos los paquetes hacia el router de túnel de salida de proxy (PETR) o los nodos de borde del fabric SDA.
- El nodo de borde del fabric encapsula el paquete IP original en VXLAN y reenvía el paquete hacia los nodos de borde del fabric SDA.
- El nodo de borde desencapsula el paquete y ejecuta una búsqueda de IP contra la dirección IP de destino del paquete original, y reenvía el paquete hacia el siguiente salto apropiado, que es más que probable que sea un router de fusión ascendente que no forme parte del entramado SDA.
- A continuación, para el tráfico de retorno dirigido al terminal dentro del entramado SDA, el paquete es recibido por el router Fusion y también ejecuta una búsqueda de IP en la dirección IP de destino y la reenvía hacia el siguiente salto apropiado, que es un nodo de borde.
- El nodo de borde de fabric consulta a CEF, que se deriva de LISP, para determinar qué nodo de borde de fabric está asociado con el terminal, encapsular el paquete original en VXLAN y enviarlo.
- El extremo del fabric desencapsula el paquete y reenvía el paquete original hacia el terminal.
Flujo de trabajo básico
Topología de referencia
A efectos de este ejemplo, los switches C9000v funcionan como bordes de fabric y bordes colocados. Los routers Fusion y el router de Internet son routers CSR1Kv. El punto final en 10.47.4.2 que está en la VLAN 1026 y forma parte de la red virtual (VN) red_vn está intentando hacer ping a 8.8.8.8 que existe como una interfaz Loopback0 en el router de Internet.
