Ejemplo: configuración de PBB con EVPN de host único
En este ejemplo se muestra cómo integrar el puente troncal del proveedor (PBB) con la VPN Ethernet (EVPN). Con esta integración, las operaciones del plano de control en el núcleo se simplifican, proporcionando mejoras de convergencia y escalabilidad más rápidas que el EVPN normal. Las aplicaciones PBB-EVPN incluyen interconexión del centro de datos (DCI) y servicios E-LAN Ethernet de operadora.
Requisitos
En este ejemplo se utilizan los siguientes componentes de hardware y software:
Tres dispositivos perimetrales de proveedor (PE), cada uno conectado a sitios de clientes de una sola base.
Cuatro dispositivos perimetrales de cliente (CE) de base única en los dispositivos PE.
Junos OS versión 17.2R1 o posterior ejecutándose en todos los enrutadores PE.
Antes de empezar:
Configure las interfaces del dispositivo.
Configure un IGP, como OSPF, en todos los dispositivos PE.
Establezca una sesión BGP interna entre los dispositivos PE.
Habilite RSVP en los dispositivos PE.
Configure MPLS y rutas de conmutación de etiquetas (LSP) entre los dispositivos PE.
Descripción general y topología
A partir de Junos OS versión 17.2R1, PBB se integra con Ethernet VPN (EVPN) para permitir una reducción significativa en el aprendizaje del plano de control en todo el núcleo, permitiendo que una gran cantidad de servicios de capa 2, como la conectividad del centro de datos, transiten la red de una manera simplificada.
En una red PBB-EVPN, el dispositivo de puente de núcleo troncal (BCB) en el núcleo de PBB se sustituye por MPLS, conservando las propiedades de escalado de servicio del puente de borde troncal (BEB) de PBB. El componente B (instancia de enrutamiento del proveedor) se señala mediante la señalización BGP de EVPN y se encapsula dentro de MPLS mediante dispositivos perimetrales del proveedor (PE) y del proveedor (P). Por lo tanto, PBB-EVPN combina la vasta propiedad de escalado de PBB con la simplicidad de una red central MPLS básica tradicional, lo que resulta en una reducción significativa en la cantidad de información de estado de toda la red, a diferencia del PBB regular.

de base única
En la figura 1, PBB está integrado con EVPN, donde los dispositivos CE son de base única en los dispositivos PE1, PE2 y PE3.
Configuración
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.
