Abstract
(EN)
Implementation of a VPN service such as a VPLS (Virtual Private Local area network Service) is performed utilizing a two-stage process. Two-stage process involves providing notification of whether a PE (Provider Edge) router in a label-switching network has VPLS capability. Notification can include broadcasting a message from a PE router to remote PE routers in the label-switching network to indicate whether the broadcasting PE router is VPLS enabled. A second stage of the two-stage process involves, based on receiving a notification that a PE router is VPLS enabled, generating a query message to discover a set of VPLS instances to which the broadcasting PE router belongs. A given PE router generating the query message can identify other PE routers in the label-switching network associated with the same VPLS for purposes of setting up the VPLS in the label-switching network.

L'invention porte sur la mise en oeuvre d'un service de réseau privé virtuel (VNP) tel qu'un service de réseau privé virtuel local (VPLS) qui s'effectue en deux étapes consistant: (i) à obtenir notification que le routeur PE (de bord de prestataire) d'un réseau à commutation d'étiquettes à la capacité VPLS, la vérification pouvant consister à faire diffuser sur le réseau à commutation d'étiquettes par le routeur PE à des routeurs PE distants, un message indiquant qu'il a bien la capacité VPLS, et (ii) la notification reçue confirmant la capacité VPLS du routeur PE, à créer un message d'interrogation pour découvrir un ensemble d'instances VPLS auxquelles appartient le routeur PE diffuseur. Un routeur PE donné produisant le message d'interrogation peut identifier d'autres types de routeurs dans le réseau à commutation d'étiquettes associé au même VPLS afin d'installer le VPLS dans le réseau à commutation d'étiquettes.
