Ejemplo: conservación del ancho de banda con espionaje IGMP en un entorno EVPN-VXLAN
En este ejemplo se muestra cómo configurar la supervisión IGMP en dispositivos perimetrales de proveedor (PE) en una LAN virtual extensible VPN Ethernet (EVPN). Cuando el tráfico de multidifusión llega al núcleo de VXLAN, un dispositivo PE configurado con EVPN reenvía el tráfico solo a las interfaces de acceso local donde hay escuchas IGMP.
Requisitos
En este ejemplo se utilizan los siguientes componentes de hardware y software:
Dos conmutadores QFX10000 configurados como dispositivos PE multihost conectados al CE, uno QFX10000 dispositivo configurado como dispositivo PE conectado a los PE multihost y un QFX5110 configurado como dispositivo CE.
Junos OS versión 17.2R1 o posterior ejecutándose en todos los dispositivos.
Visión general
La supervisión IGMP se utiliza para restringir el tráfico de multidifusión en un dominio de difusión a receptores y dispositivos de multidifusión interesados. En un entorno con tráfico de multidifusión significativo, la supervisión IGMP conserva el ancho de banda porque el tráfico de multidifusión solo se reenvía en aquellas interfaces en las que hay escuchas IGMP. IGMP está habilitado para administrar la pertenencia a grupos de multidifusión.
Cuando se habilita la supervisión IGMP en cada VLAN, el dispositivo anuncia rutas EVPN de tipo 7 y tipo 8 (rutas de unión y salida de sincronización) para sincronizar los estados de unión y salida IGMP entre los dispositivos pares multihost en la instancia de EVPN. En el lado de acceso, los dispositivos solo reenvían tráfico de multidifusión a los oyentes suscritos. Sin embargo, el tráfico de multidifusión sigue inundado en el núcleo de EVPN incluso cuando no hay receptores remotos.
La configuración de la supervisión IGMP en un entorno EVPN-VXLAN requiere lo siguiente:
Dispositivos PE pares multiconexión en modo totalmente activo.
Solo IGMP versión 2. (Las versiones 1 y 3 de IGMP no son compatibles).
Supervisión IGMP configurada en modo proxy para que el PE se convierta en el cuestionario IGMP para las interfaces de acceso local.
Esta función admite el reenvío de multidifusión dentro de VLAN y entre VLAN. Puede configurar un dispositivo PE para que realice una o ambas cosas. En este ejemplo, para habilitar el reenvío entre VLAN, cada dispositivo PE se configura como un punto de encuentro (RP) de multidifusión independiente del protocolo (PIM) definido estáticamente para habilitar el reenvío de multidifusión. También puede configurar la distributed-dr instrucción en el nivel de [edit protocols pim interface interface-name] jerarquía para cada interfaz IRB. Este modo permite a PIM reenviar el tráfico de multidifusión de forma más eficaz al deshabilitar las características de PIM que no son necesarias en este escenario. Cuando se configura esta instrucción, PIM omite el estado de enrutador designado (DR) de la interfaz al procesar los informes IGMP recibidos en la interfaz. Cuando la interfaz recibe el informe IGMP, el dispositivo PE envía mensajes PIM ascendentes de unión para extraer el flujo de multidifusión y reenviarlo a la interfaz, independientemente del estado de DR de la interfaz.
Topología
La figura 1 ilustra un entorno EVPN-VXLAN en el que dos dispositivos PE (PE1 y PE2) están conectados al dispositivo perimetral del cliente (CE). Estos PE tienen doble origen en modo activo-activo para proporcionar redundancia. Un tercer dispositivo PE reenvía el tráfico a los dispositivos PE que se enfrentan al CE. IGMP está habilitado en interfaces de enrutamiento y puente integrados (IRB). El dispositivo CE aloja cinco VLAN; El espionaje IGMP está habilitado en todas las VLAN. Dado que esta implementación no admite el uso de un enrutador de multidifusión, cada VLAN del PE se habilita como una consulta IGMP de capa 2. Los dispositivos PE multihost reenvían el tráfico hacia el CE solo en aquellas interfaces donde hay oyentes IGMP.

Para configurar IGMP Snooping en un entorno EVPN-VXLAN, realice estas tareas:
- Configuración rápida de CLI
- Configuración de PE1
- Configuración de PE2
- Configuración del dispositivo CE
- Configuración de PE3
Configuración rápida de CLI
Para configurar rápidamente este ejemplo, copie los siguientes comandos, péguelos en un archivo de texto, elimine los saltos de línea, cambie los detalles necesarios para que coincidan con su configuración de red, copie y pegue los comandos en la CLI en el nivel de jerarquía y, a continuación, ingrese commit desde el [edit] modo de configuración.

Significado
El SG Sync campo es Enabled y el IM Core next-hop muestra una ruta válida.
Verificar que se aprenden las direcciones de origen y que se reenvía el tráfico de multidifusión
Propósito
Verifique en cada PE que los receptores de multidifusión hayan aprendido la interfaz de origen para el túnel VXLAN.
Acción
Desde el modo operativo, escriba el show evpn igmp-snooping database extensive l2-domain-id 1 comando y los show igmp snooping evpn database vlan VLAN1 comandos.
Estos comandos muestran la salida para VLAN1. Puede usarlos para mostrar la salida de cada VLAN configurada
Desde el modo operativo, ingrese el para verificar que se ha aprendido la show evpn multicast-snooping next-hops interfaz descendente.
