Ejemplo: Configuración de la interoperación de VPLS basada en BGP H-VPLS y LDP
En este ejemplo, se muestra cómo configurar el servicio de LAN privada virtual jerárquica (H-VPLS) en un escenario que usa VPLS basado en LDP y VPLS basado en BGP que interoperan en una implementación multiconexión. Este escenario es útil cuando la implementación de un cliente tiene los dos tipos diferentes de VPLS en uso y debe integrarlos. Otro ejemplo es cuando el ISP-A ejecuta VPLS basado en BGP e ISP-B ejecuta el VPLS basado en LDP, y los dos ISP están fusionando sus redes.
Requisitos
No se requiere ninguna configuración especial más allá de la inicialización del dispositivo antes de configurar este ejemplo.
Visión general
En este ejemplo, los dispositivos PE2 y PE3 actúan como enrutadores de borde (PE) de proveedor de internet con terminación VPLS basada en BGP y LDP.
Los dispositivos de este ejemplo tienen las siguientes funciones:
BGP VPLS solo PE— Dispositivo PE1
LDP VPLS solo PE— Dispositivo PE4
BGP-LDP VPLS PE— Dispositivos PE2 y PE3
La figura 1 muestra la topología utilizada en este ejemplo.
Figura 1: H-VPLS con interoperación VPLS basada en LDP y BGP
Desde el dispositivo PE4, el pseudocable hasta el dispositivo PE3 es la ruta principal o que funciona. El pseudocable dispositivo PE2 es la ruta de copia de seguridad.
La configuración rápida de CLI muestra la configuración de todos los dispositivos en la Figura 1. La sección Procedimiento paso a paso describe los pasos en los dispositivos PE1, PE2 y PE4.

Si ha terminado de configurar los dispositivos, ingrese commit desde el modo de configuración.
Verificación
Confirme que la configuración funciona correctamente. En una situación de multiconexión con VPLS BGP-LDP, los pseudocables de LDP están en estado inactivo para el PE de respaldo (DISPOSITIVO PE2). Mientras que en el VPLS PE (dispositivo PE4) solo para LDP, los pseudocables a los dispositivos de PE BGP-LDP primarios y de respaldo están en estado ascendente.
- Verificar las conexiones VPLS
- Activar manualmente un conmutador desde el pseudocable activo al pseudocable de respaldo
- Comprobación de la conectividad
- Comprobar las tablas de enrutamiento VPN de capa 2 del BGP
- Comprobación de las tablas de enrutamiento de circuitos de capa 2
Verificar las conexiones VPLS
Propósito
Verifique que las conexiones VPLS funcionen como se esperaba.
Acción
Desde el modo operativo, ingrese el show vpls connections comando.

Significado
En el dispositivo PE1, la conexión BGP-VPLS al dispositivo PE2 está activa. En una condición de estado estable, el dispositivo PE2 es el enrutador principal y tiene todos los pseudocables que terminan en él. El tráfico fluye de CE1 a PE1, a PE2, a PE4 a CE4.
En el dispositivo PE2, la conexión BGP-VPLS al dispositivo PE1 está activa. La conexión al dispositivo PE3 está en estado RN. La conexión LDP-VPLS al dispositivo PE4 está activa.
En el dispositivo PE3, todas las conexiones VPLS están en estado LN. Esto se espera porque el dispositivo PE3 es la copia de seguridad.
En el dispositivo PE4, el enrutador VPLS solo para LDP, el pseudocable principal al dispositivo PE2 y el pseudocable de respaldo al dispositivo PE3 están en estado ascendente.
Activar manualmente un conmutador desde el pseudocable activo al pseudocable de respaldo
Propósito
Compruebe que cuando el dispositivo PE2 deja de estar disponible, el flujo de tráfico cambia al dispositivo PE3.
Acción
En el dispositivo PE2, desactive las interfaces.
