Ce document montre comment configurer la commutation multiprotocole MPLS (Multiprotocol Label Switching) de réseau privé virtuel (VPN) sur ATM avec des routeurs Cisco 7500 en tant que routeurs de périphérie d'étiquette (LER) et des commutateurs LightStream 1010 en tant que routeurs de commutation d'étiquette (LSR). Deux routeurs connectés par Ethernet, chacun sur un site client distant, font partie d'un VPN. Dans ce document, nous examinons les configurations de périphériques de bout en bout et les commandes show utiles.
Aucune exigence spécifique n'est associée à ce document.
Pour plus d'informations sur les conventions utilisées dans ce document, reportez-vous à Conventions relatives aux conseils techniques Cisco.
Cette section vous fournit des informations pour configurer les fonctionnalités décrites dans ce document.
Ce document utilise la configuration réseau suivante :
La configuration actuelle contient les éléments suivants dans la terminologie VPN :
CE = routeur de périphérie client
PE = routeur de périphérie du fournisseur
P=Routeur fournisseur
La configuration actuelle contient les éléments suivants dans la terminologie MPLS :
LER = routeur de périphérie d'étiquette
LSR = Routeur de commutation par étiquette
TDP/LDP = Tag Distribution Protocol/Label Distribution Protocol
Ce document utilise les configurations suivantes :
PE1 et PE2 sont les ler de notre réseau ATM.
P1 et P2 sont les LSR.
CE1 et CE2 sont des routeurs de périphérie client qui ne connaissent pas et n'exécutent pas de VPN ou MPLS.
CE1 et CE2 sont connectés à Ethernet à PE1 et PE2 respectivement, et exécutent le protocole RIP (Routing Information Protocol).
PE1, PE2, P1 et P2 utilisent le protocole OSPF (Open Shortest Path First) et se trouvent tous dans la zone 0. OSPF est le protocole IGP (Interior Gateway Protocol) utilisé dans le réseau ATM. La commutation Tag-Switching est utilisée sur les interfaces ATM des quatre périphériques ATM. Le protocole TDP (Tag Distribution Protocol) attribue des balises aux routes OSPF.
PE1 et PE2 sont des homologues MP-BGP (Multiprotocol-Border Gateway Protocol).
Les routes RIP sont redistribuées dans MP-BGP. Routes MP-BGP redistribuées dans RIP sur les routeurs PE1 et PE2.
La configuration gère des tables de routage VRF distinctes dans les routeurs PE1 et PE2.
Le nom du VPN utilisé dans cet exemple est NEW.
