Introducción

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, miramos las configuraciones de dispositivo de extremo a extremo y los comandos show útiles.

Configurar

En esta sección encontrará la información para configurar las funciones descritas en este documento.

Diagrama de la red

En este documento, se utiliza esta configuración de red:

/image/gif/paws/10533/vpn-mpls-1.gif

Descripción de la Red

La configuración actual contiene estos elementos en terminología VPN:

  • CE = Router borde del cliente

  • PE = router de borde del proveedor

  • Router de P=Provider

La configuración actual contiene estos elementos en terminología MPLS:

  • LER = Router de borde de etiqueta

  • LSR = Label Switch Router

  • TDP/LDP = Tag Distribution Protocol/Label Distribution Protocol

Configuraciones

En este documento, se utilizan estas configuraciones:

  • El PE1 y el PE2 son los LER en nuestra red ATM.

  • El P1 y el P2 son los LSR.

  • El CE1 y el CE2 son el Routers de la frontera del cliente que está inconsciente y no realiza el VPN o el MPLS.

  • El CE1 y el CE2 son Ethernet conectado con el PE1 y el PE2 respectivamente, y realizan el Routing Information Protocol (RIP).

  • El PE1, el PE2, el P1 y el P2 hacen el Open Shortest Path First (OSPF) y son todo en el área 0. OSPF es el Interior Gateway Protocol (IGP) usado en la red ATM. El Tag Switching se utiliza en las interfaces ATM en los cuatro dispositivos ATM. El (TDP) del Tag Distribution Protocol asigna las etiquetas a las OSPF rutas.

  • El PE1 y el PE2 son pares del Multiprotocol-Border Gateway Protocol (MP-BGP).

  • Las rutas del RIP se redistribuyen en el MP-BGP. Rutas MP-BGP redistribuidas en el RIP en el Routers PE1 y PE2.

  • La configuración mantiene las tablas de ruteo separadas VRF en el Routers PE1 y PE2.

  • El nombre del VPN usado en este ejemplo es NUEVO.
