La extensión que permite que BGP transporte la información de IP de Capa 2 MAC y Capa 3 es EVPN y utiliza Multi-Protocol Border Gateway Protocol (MP-BGP) como protocolo para distribuir la información de alcance que pertenece a la red superpuesta VXLAN.
Resolución de problemas de EVPN VXLANv6 en switches Catalyst serie 9000
Introducción
Este documento describe cómo resolver problemas de EVPN VXLANv6 en switches Catalyst serie 9000.
Prerequisites
Requirements
Cisco recomienda que tenga conocimiento sobre estos temas:
- función VxLAN de EVPN unidifusión, BGP y MVPN (red privada virtual multidifusión).
- Unidifusión IPv4 e IPv6
- Conceptos de multidifusión y funcionamiento de la multidifusión
Componentes Utilizados
La información que contiene este documento se basa en las siguientes versiones de software y hardware.
- Catalyst 9000 Series Switches
Nota: los modelos 9200, 9500X y 9600X no admiten VXLANv6
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.
Terminology
| EVPN |
Red privada virtual Ethernet |
|
| VXLAN |
LAN extensible virtual (red de área local) |
VXLAN está diseñado para superar las limitaciones inherentes de las VLAN y el STP. Se propone un estándar IETF [RFC 7348] para proporcionar los mismos servicios de red Ethernet de capa 2 que las VLAN, pero con mayor flexibilidad. Funcionalmente, es un protocolo de encapsulación MAC-in-UDP que se ejecuta como una superposición virtual en una red subyacente de Capa 3. |
| VTEP |
Terminal de túnel virtual |
Este es el dispositivo que realiza la encapsulación y desencapsulación |
| EVI |
Instancia de EVPN |
La instancia de EVPN (EVI) se representa mediante el identificador de red virtual (VNI). Un EVI representa una VPN en un router PE. Cumple la misma función que un routing y reenvío de VPN IP (VRF), y a las EVI se les asignan objetivos de ruta de importación y exportación (RT) |
| NVE |
Interfaz virtual de red |
Interfaz lógica donde se produce la encapsulación y la desencapsulación |
| VNI |
identificador de red VXLAN |
Identifica de forma exclusiva cada subred o segmento de capa 2. Existen dos tipos de VNI: Simétrico (L2VNI): los VTEP tienen el mismo VNI Asimétrico (L3VNI): Los VTEP no tienen el mismo VNI y se enrutan a través de un único VNI común. |
| VAGABUNDO |
Difusión, unidifusión desconocida, multidifusión |
El tráfico BUM se envía a través del grupo Mcast vinculado al VNI en la configuración NVE. |
| TRM |
Multidifusión enrutada por arrendatario |
Solución basada en BGP-EVPN que permite el routing multidifusión entre orígenes y receptores conectados en VTEPS en el fabric VxLAN [RFC7432]. Existen dos tipos L2TRM (TRM de capa 2) y L3TRM (TRM de capa 3) |
| MDT |
Árbol de distribución de multidifusión |
El árbol de multidifusión creado entre VTEP para la encapsulación y la tunelización del tráfico de multidifusión de arrendatarios. |
| PVLAN |
VLAN privada |
Divide el dominio de broadcast Ethernet de una VLAN en subdominios, lo que le permite aislar entre sí los puertos en el switch. |
| MIB |
Base de información para administración |
R Objeto de monitor del Protocolo simple de administración de red (SNMP) |
| PIM-BIDIR |
Multidifusión independiente de protocolo bidireccional |
Tipo de PIM en el que el tráfico sólo se reenvía a lo largo de un árbol compartido que tiene su raíz en el punto de encuentro (RP) del grupo. |
| VFI |
Instancia de reenvío virtual |
Puerto de puente virtual que puede realizar funciones de puente nativas, como reenvío, basadas en la dirección MAC de destino, el aprendizaje y la antigüedad de la dirección MAC de origen, etc. |
| IRB |
Routing y puente integrados |
habilita una VPN de capa 2 y una superposición de VPN de capa 3 que permite que los hosts finales de la superposición se comuniquen entre sí dentro de la misma subred y entre diferentes subredes dentro de la VPN. |
| IMET |
Etiqueta Ethernet de multidifusión inclusiva |
también llamado BGP Route Type 3 (RT3), para la detección automática de peers remotos para configurar los túneles BUM sobre VXLAN. Las rutas IMET llevan los VNI remotos (de salida) anunciados de los peers remotos, que pueden ser diferentes de los VNI locales. Estos VNI remotos se denominan VNI asignados en sentido descendente. |
| DAG |
Gateway Anycast Distribuido |
Función de gateway predeterminada en todos los VTEP. La misma IP de gateway reside en todos los VTEP y permite la movilidad en el fabric. |
| IR(B) |
Routing integrado (y conexión en puente) |
Habilita una VPN de Capa 2 y una superposición de VPN de Capa 3 que permite que los hosts finales a través de la superposición se comuniquen entre sí dentro de la misma subred y a través de diferentes subredes dentro de la VPN. |
| RNH |
Salto siguiente remoto |
El VTEP remoto |
| RPF |
Reenvío de Trayectoria Inversa |
Ruta de acceso unidifusión de vuelta al origen. Los paquetes de multidifusión entrantes no se aceptan/reenvían a menos que se reciban en la misma ruta que la tabla de ruteo de unidifusión. ('ip multicast multipath', casos de uso excluidos). |
| RP |
Punto de encuentro |
Función que desempeña un dispositivo en el modo disperso de PIM. El punto de encuentro común para fuentes y receptores de multidifusión. |

Topología VXLANv6 de EVPN Greenfield
Verificar (Greenfield o doble pila)
Antes de realizar la resolución de problemas por flujo de tráfico, se debe verificar la información del nivel de topología de EVPN VXLANv6 para garantizar un funcionamiento correcto. Esta sección muestra los comandos de verificación para ambas implementaciones. Elija los comandos de verificación aplicables en función de la implementación.
Conectividad subyacente
Verifique la conectividad subyacente de IPv6 entre VTEP y Spines (para VXLANv6 Greenfield, solo necesita verificar la conectividad subyacente de IPv6).

Nota: En el caso de rutas IMET de salto doble de siguiente salto, el atributo de túnel PMSI en la ruta importada EVI tiene su dirección de salto siguiente principal como identificador de túnel. BGP reemplaza eso por la dirección de próximo salto secundaria del atributo encap del túnel si la preferencia local es la de la familia de direcciones de próximo salto de encapsulamiento del túnel. En este ejemplo, aunque BGP muestra el extremo del túnel como 10.2.2.2, mientras se instala en L2RIB, reemplaza con 2001:DB8:2::2. Esto se hace porque BGP no cambia la entrada de atributo en la tabla de atributos.

Reenvío de tráfico BUM (replicación de multidifusión)
Esta sección proporciona un ejemplo para resolver problemas del tráfico BUM de VTEP1 a VTEP2 en EVI 2 donde el tipo de replicación se configura como estático.
Verifique que el Tipo de Replicación esté configurado en Estático para el EVI en el Administrador de EVPN en ambos VTEP
-
Ambos VTEP deben configurarse con el mismo grupo de multidifusión subyacente para el mismo EVI. La información del grupo de multidifusión subyacente proviene de NVE. Verifique la configuración de la interfaz NVE si no está configurada correctamente.

Reenvío unidifusión entre VTEP (misma VLAN mediante L2VNI)
Esta sección proporciona un ejemplo para la resolución de problemas del tráfico unicast:
- desde el host H11 conectado a VTEP1 en la VLAN 11 (con dirección MAC aabb.0000.0011 e IP 192.168.11.11)
- al host H31 conectado a VTEP3 en la VLAN 11 (con la dirección MAC aabb.0000.0031 y la dirección IP 192.168.11.31).
Verifique que ARP para la dirección IP de destino se resuelva en el host de origen
-
Los paquetes ARP se gestionan como parte del tráfico BUM en el fabric EVPN. Si ARP no se resuelve en un host, utilice los pasos de troubleshooting para el reenvío de tráfico BUM de EVPN para el tipo de replicación configurado apropiado utilizado en su red.

Transferencia de EVPN entre la Hoja Fronteriza y el Router VPN MPLS
Esta sección se aplica tanto a la transferencia L3VPN como a la entrega Multi VRF (VRF Lite/PE-CE)
Verifique el prefijo IP en el router VPN remoto (R1) anunciado a Border-Leaf (vtep3) en el fabric EVPN
- El nodo VPN R1 tiene una base MPLS, es una pila única. El nodo de hoja de borde Leaf3 y el resto del fabric EVPN pueden estar en modo de pila única o doble,
Verifique estos puntos si hay un problema de tráfico con EVPN Route-type 5 (RT5):
Paso 1. Confirmar que la ruta RT5 está en la tabla global EVPN
Paso 2. Verifique que la ruta se importe en VRF
- Debe tener la RT de importación configurada para el VRF.
- Costura de Route-Target (RT) para un escenario de transferencia en border-leaf/border-spine
- Asegúrese de que la configuración BGP EVPN "advertise l2vpn evpn" esté presente en el vrf de la familia de direcciones
- Asegúrese de que se realice la configuración de importación correcta en la familia de direcciones l2vpn evpn y en la entrega de L3VPN de error vpnv4/vpnv6 (en el nodo de borde), como se muestra aquí:

Paso 3. Verifique el estado de VTEP local con este comando
VTEP3#show bgp l2vpn evpn local-vtep vrf red
Local VTEP vrf red:
Protocol: IPv4
RMAC Address: AABB.CC81.F700
VTEP-IP:10.3.3.2
SEC-VTEP-IP:2001:DB8:3::2
VNI: 30000
BDI:Vlan3
Protocol: IPv6
RMAC Address: AABB.CC81.F700
VTEP-IP:10.3.3.2
SEC-VTEP-IP:2001:DB8:3::2
VNI: 30000
BDI:Vlan3
Paso 4. Verifique que Remote Nexthop (RNH) esté instalado para el VRF.
- RNH garantiza la adyacencia para la ruta instalada en el RIB.
- BGP instala la ruta RT5 en la tabla VPN BGP, que luego se instala en la tabla IP VRF correspondiente.
- La adyacencia del nexthop instalado se garantiza mediante los parámetros del VTEP remoto (como RMAC, eVNI y RTEP). RTEP sería igual que la dirección de próximo salto de la ruta.
- BGP instala el RNH en el L3-EVPN/NVE directamente.
Cuando RNH no es correcto, la entrada CEF para las rutas tendría adyacencia incompleta.
- En un escenario de doble pila, debe verificar si el siguiente salto para la ruta y el RTEP RNH (extremo de túnel remoto) son iguales.
Cuando una ruta no está instalada o la ruta instalada tiene adyacencia incompleta, verifique los parámetros RNH y correlaciónelos con la configuración en el nodo local y el valor de los parámetros en la ruta.

[30000 / AABB.CC81.F500 / 2001:DB8:1::2 / yes]
Paso 5: Comprobar el estado del par NVE
- El estado del peer NVE es activo cuando BGP recibe una ruta del peer remoto y se instala correctamente en el subsistema RIB y L3-EVPN/NVE.
