Este documento proporciona una configuración de ejemplo para la red privada virtual (VPN) de switching de etiquetas multiprotocolo (MPLS) sobre ATM, el paquete sobre SONET/SDH (POS) y el protocolo de reutilización espacial (SRP) en los routers de switch Gigabit (GSR) Cisco 12000.
Estos acrónimos se utilizan en este documento.
CE : router de borde del cliente
PE: router de borde del proveedor

MPLS está disponible para admitir varias interfaces físicas. Estas interfaces incluyen ATM, POS y SRP. Estas interfaces se utilizan normalmente para conexiones de red troncal debido a su alta compatibilidad con el ancho de banda. La función MPLS VPN permite a los proveedores de servicios interconectar varios sitios sin necesidad de ATM, POS o SRP en el lado del cliente.
Hay dos implementaciones de MPLS sobre ATM. Una es el uso del identificador de ruta virtual (VPI) y del canal virtual identificado (VCI) como la etiqueta que también se conoce como MPLS "basado en celdas" sobre ATM. Esta implementación se documenta bajo RFC 3035 . La segunda implementación de ATM es el uso del "encabezado shim" MPLS que también se conoce como MPLS basado en paquetes sobre ATM. Este encabezado shim se inserta entre los encabezados de Capa 2 y Capa 3. El formato del encabezado shim se documenta bajo RFC 3032 . Esta configuración de ejemplo se basa en la implementación del "encabezado shim" para la interfaz ATM.
Packet over Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) es una tecnología que coloca la capa IP directamente sobre la capa SONET. Elimina la sobrecarga necesaria para ejecutar IP sobre ATM sobre SONET. POS admite el formato de encapsulación múltiple. Estos son PPP, HDLC y Frame Relay. El encabezado shim se utiliza para proporcionar soporte MPLS. Esta configuración de ejemplo utiliza la encapsulación HDLC predeterminada en las interfaces POS de Cisco.
El protocolo de reutilización espacial (SRP) es una tecnología de capa 2 que proporciona resistencia en el nivel de capa 2. También se ejecuta sobre SONET/SDH. La implementación del encabezado shim proporciona soporte MPLS.

Esta lista enumera algunas consideraciones realizadas en la configuración de ejemplo:
El servicio de configuración de ejemplo de MPLS VPN EIGRP enruta desde los CE. El Id. de bug Cisco CSCds09932 (sólo clientes registrados) ha introducido el soporte EIGRP para MPLS VPN con Cisco IOS Software Release 12.0(22)S. Esto se ha trasladado a Cisco IOS Software Release 12.2T a través del Id. de bug Cisco CSCdx26186 (sólo clientes registrados) a partir de Cisco IOS Software Release 12.2(15)T. La aplicación del mismo VRF a múltiples instancias EIGRP no se soporta y puede bloquear el router. Una verificación de este problema se integró posteriormente con el ID de bug de Cisco CSCdz40426 (sólo clientes registrados) . Consulte Soporte de VPN MPLS para EIGRP entre el Borde del Proveedor y el Borde del Cliente para obtener más información sobre el soporte de VPN MPLS para EIGRP.
El sistema autónomo EIGRP es el mismo en ambos routers CE. El sistema autónomo BGP es el mismo en ambos routers PE.
La estructura básica MPLS se basa en interfaces POS, ATM y SRP y se configura con OSPF y MP-BGP. La conexión entre PE y CE es Fast Ethernet.
