Dans le cadre de la documentation associée à ce produit, nous nous efforçons d’utiliser un langage exempt de préjugés. Dans cet ensemble de documents, le langage exempt de discrimination renvoie à une langue qui exclut la discrimination en fonction de l’âge, des handicaps, du genre, de l’appartenance raciale de l’identité ethnique, de l’orientation sexuelle, de la situation socio-économique et de l’intersectionnalité. Des exceptions peuvent s’appliquer dans les documents si le langage est codé en dur dans les interfaces utilisateurs du produit logiciel, si le langage utilisé est basé sur la documentation RFP ou si le langage utilisé provient d’un produit tiers référencé. Découvrez comment Cisco utilise le langage inclusif.

Ce document décrit la procédure de configuration du protocole PPPoE (Point to Point Protocol over Ethernet) sur le routeur de service d'agrégation Cisco ASR 920 agissant en tant que client.
Cisco vous recommande de connaître la connectivité de bout en bout de la couche 1.
Les informations de ce document sont basées sur le matériel Cisco ASR 920.
Les informations de ce document ont été créées à partir des périphériques d'un environnement de travaux pratiques spécifique. Tous les périphériques utilisés dans ce document ont démarré avec une configuration effacée (par défaut).
Note: Si votre réseau est en ligne, assurez-vous de bien comprendre l’incidence possible des commandes.
Note: Utilisez l'Outil de recherche de commande (clients inscrits seulement) pour obtenir plus d'informations sur les commandes utilisées dans cette section.
La configuration sur les routeurs s'effectue de l'arrière vers l'arrière (client et serveur).
Il est spécifique à la plate-forme ASR 920.
