Introducción

Este documento describe el propósito de los infra-vlans del nve del sistema ordena en las telas extensibles virtuales de los Ethernetes VPN (BGP EVPN del protocolo Protocolo de la puerta de enlace marginal (BGP) LAN VXLAN) basadas en los 9000 Switch del nexo de Cisco que funcionan con el sistema operativo NX-OS.

Cuando se configuran los 9000 Switch del nexo como la hoja VXLAN cambia también conocido como extremo del túnel VXLAN señalan (VTEP) en el dominio del canal del puerto virtual (vPC), usted debe tener una adyacencia de reserva de la encaminamiento entre ellos sobre el par-link del vPC con el uso de los vlans del interfaz en caso de una falla de link ascendente. Este vlan se debe ser local al Switches y no estirar a través de la tela VXLAN.

Asegúrese que el comando de los infra-vlans del nve del sistema exista en el nexo 9000 Plataformas con CloudScale ASIC (Tahoe) como los 9300 Switch del nexo que termine en EX, FX y FX2 para especificar el vlan usado mientras que uplink puede remitir correctamente el marco con la encapsulación VXLAN.

Nota: Este documento es no corresponde a los 9000 Switch del nexo de Cisco que se ejecutan en el modo céntrico de la infraestructura de la aplicación (ACI) y manejado por el regulador de la infraestructura de la directiva de la aplicación de Cisco (APIC).

Prerrequisitos

Requisitos

Cisco recomienda que tenga conocimiento sobre estos temas:

Software del nexo NX-OS
BGP EVPN VXLAN

Componentes Utilizados

La información que contiene este documento se basa en las siguientes versiones de software y hardware.

Cisco N9K-C93180YC-EX
Versión 7.0(3)I7(6) NXOS

La información que contiene este documento se creó a partir de los dispositivos en un ambiente de laboratorio específico. Todos los dispositivos que se utilizan en este documento se pusieron en funcionamiento con una configuración verificada (predeterminada). Si tiene una red en vivo, asegúrese de entender el posible impacto de cualquier comando.

Nota: Este documento hace uso del conmutador de la hoja de los términos, del VTEP y del ToR alternativamente.

Configurar

En este decorado, HOJEAN A y la HOJA B son VTEPs en el vPC.

Vlan 777 se ha elegido para participar en el protocolo de la encaminamiento de la arpillera que en este caso es Open Shortest Path First (OSPF).

En el Switches de cada HOJA A y de la HOJA B, el OSPF ha formado una adyacencia con el conmutador de la ESPINA DORSAL sobre uplink y entre él sobre el par-link del vPC.

El OSPF o el Intermediate System-to-Intermediate System (IS-IS) puede ser el protocolo de la encaminamiento funcionando en la arpillera.

Nota: No se configura ningún comando del vn-segmento conforme a las 777 secciones de configuración vlan. Esto indica que el vlan no está estirada a través de la tela VXLAN y es local en el Switches.

Agregue los infra-vlans del nve del sistema ordenan en el modo de configuración global y eligió 777 vlan puesto que es el vlan usado para la adyacencia OSPF de la arpillera.

Nota: Los infra-vlans del nve del sistema se requieren solamente en el nexo 9000 con CloudScale ASIC (Tahoe) como el nexo 9300 que termina en EX, FX y FX2.

Nota: Los interfaces de la capa 3 son la recomendación para que uplinks transporte el tráfico VXLAN dentro de la tela. Los sub-interfaces de la capa 3 no se utilizan. Para utilizar los vlans del interfaz para transportar el tráfico VXLAN, asegúrese que el vlan también está identificada con los infra-vlans del nve del comando system.

Troubleshooting

En caso que el conmutador de la HOJA A sufra de una falla de link ascendente y conecta no más directamente con el conmutador de la ESPINA DORSAL, el reachability se puede todavía lograr con infra-VLAN sobre el par-link del vPC usado como de reserva uplink hacia el conmutador de la ESPINA DORSAL.
