This sample configuration shows a Cisco 1417 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 1417 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.X, 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
1417. 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 1417.
