Introduction

This document provides a sample configuration for a Cisco 1417 Digital Subscriber Line (DSL) Router that connects to a Cisco 6130 DSL Access Multiplexer (DSLAM) and terminates on a Cisco 6400 Universal Access Concentrator-Node Route Processor (UAC-NRP).

The Cisco 1417 configuration has Point to Point Protocol over ATM (PPPoA) with Network Address Translation (NAT). The IP address negotiation is turned on. The Cisco 1417 also serves as a DHCP server for the local Ethernet clients.
