Introduction

This document provides a sample configuration that shows a Cisco 827 Digital Subscriber Line (DSL) Router connecting to a Cisco 6130 Digital Subscriber Line Access Multiplexer (DSLAM) and terminating on a Cisco 6400 Universal Access Concentrator (UAC). The Cisco 827 has been configured as a Dynamic Host Configuration Protocol (DHCP) server with PPP over ATM (PPPoA).

The Internet Service Provider (ISP) has given the subscriber a range of IP addresses, 10.0.0.1 to 10.0.0.?, with a mask of 255.0.0.0. IP address "10.0.0.1" will be manually configured on the Ethernet interface of the Cisco 827. The remaining IP addresses will be assigned to a DHCP pool and leased to local LAN devices attached to the Ethernet network of the Cisco 827.
