Introduction

The Cisco 1700, 2600, and 3600 series routers support the Asymmetric Digital Subscriber Line (ADSL)

WAN Interface Card (WIC). All three platforms are configured essentially the same, but there are differences

in hardware and in the Cisco IOS® Software release required for each one. Throughout this document, the

Cisco 1700/2600/3600 is referred to as the Cisco ADSL WIC.

This sample configuration shows you how to support a Point−to−Point Protocol over Ethernet (PPPoE) client

when it is connected to the Ethernet interface of a Cisco ADSL WIC.

The Cisco ADSL WIC is configured with RFC 1483

Access Concentrator (UAC) that has been configured to support PPPoE using a multipoint ATM subinterface.

The PPPoE feature allows you to initiate a PPP session on a simple bridging Ethernet connected client. The

session is transported over the ATM link via encapsulated Ethernet−bridged frames. The session can be

terminated at either a local exchange carrier central office or an Internet service provider (ISP) point of

presence.

PPPoE is a client−initiated connection. On the Customer Premises Equipment (CPE) side, a PC with an

Ethernet Network Interface Card (NIC) and the PPPoE client code are established. This PC and other PCs are

connected to the ADSL WIC Ethernet segment.

The ADSL WIC ATM interface is connected to a Cisco 6130 DSL Access Multiplexer (DSLAM) and

terminates on a Cisco 6400 UAC.
