Introduction

In this implementation, your Cisco Digital Subscriber Line (DSL) Router is unable to provide value-added services and acts as a simple Asymetric Digital Subscriber Line (ADSL) to Ethernet bridge. Therefore, you must load Point-to-Point-Protocol over Ethernet (PPPoE) client software on each PC on the LAN that requires access to the Internet.

Tip: If you are not familiar with configuring Cisco devices and would like to follow a step-by-step configuration, refer to Step-by-Step Configuration of a PC Acting as a PPPoE Client.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

This document is not restricted to specific software and hardware versions.

Conventions

Refer to Cisco Technical Tips Conventions for more information on document conventions.

Tasks to Perform

  • Configure the ATM interface (the ADSL interface) of the Cisco DSL Router with an ATM permanent virtual circuit (PVC) and encapsulation.

  • Configure bridging on your Cisco DSL Router.

  • Disable IP routing on your Cisco DSL Router.

  • Load PPPoE client software on each PPPoE client PC.

  • Configure each PPPoE client per instructions from the software vendor or Internet Service Provider (ISP); for example, domain name, username, and password).

Configure

In this section, you are presented with the information to configure the features described in this document.
