Contenu
Introduction
Ce document décrit comment configurer le serveur PPPoE (Point-to-Point Protocol over Ethernet) avec l'interface de domaine de pont (BDI) et la plage de VLAN.
Conditions préalables
Conditions requises
Cisco vous recommande de prendre connaissance des rubriques suivantes :
- La connectivité de bout en bout de la couche 1 est correcte
- Les notions de base de PPP et de PPPoE sont bien comprises
Components Used
Les informations contenues dans ce document sont basées sur les versions de matériel et de logiciel suivantes :
- HÔTE 1 - CISCO887G
- HÔTE 2 - CISCO887
- COMMUTATEUR - WS-C3560-24TS-S
- SERVEUR PPPoE - ASR1001-X
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
