Este documento muestra cómo configurar Multiprotocol Label Switching (MPLS) de Red Privada Virtual (VPN) sobre ATM con routers Cisco 7500 como Router de Borde de Etiqueta (LER) y switches LightStream 1010 como Label Switch Routers (LSR). Dos routers conectados por Ethernet, cada uno en un sitio de cliente remoto, forman parte de una VPN. En este documento, analizamos las configuraciones de dispositivos de extremo a extremo y los útiles comandos show.
No hay requisitos específicos para este documento.
En esta sección encontrará la información para configurar las funciones descritas en este documento.
En este documento, se utiliza esta configuración de red:
La configuración actual contiene estos elementos en la terminología VPN:
CE = Router de extremo del cliente
PE = Router de borde del proveedor
P=Router del proveedor
La configuración actual contiene estos elementos en la terminología MPLS:
LER = Router de borde de etiqueta
LSR = Router de switch de etiquetas
TDP/LDP = Protocolo de distribución de etiquetas/Protocolo de distribución de etiquetas
En este documento, se utilizan estas configuraciones:
PE1 y PE2 son las LER en nuestra red ATM.
P1 y P2 son los LSR.
CE1 y CE2 son routers periféricos del cliente que desconocen y no realizan VPN o MPLS.
CE1 y CE2 son Ethernet conectados a PE1 y PE2 respectivamente, y llevan a cabo el protocolo de información de routing (RIP).
PE1, PE2, P1 y P2 realizan Open Shortest Path First (OSPF) y se encuentran en el Área 0. OSPF es el protocolo de gateway interior (IGP) utilizado en la red ATM. La conmutación de etiquetas se utiliza en las interfaces ATM de los cuatro dispositivos ATM. El Protocolo de distribución de etiquetas (TDP) asigna etiquetas a las rutas OSPF.
PE1 y PE2 son pares de Multiprotocol-Border Gateway Protocol (MP-BGP).
Las rutas RIP se redistribuyen en MP-BGP. Rutas MP-BGP redistribuidas en RIP en routers PE1 y PE2.
La configuración mantiene tablas de ruteo VRF separadas en los routers PE1 y PE2.
El nombre de la VPN que se utiliza en este ejemplo es NEW.
