Select one of these PPPoE implementations for your Digital Subscriber
Line (DSL) service.
Option 1 The Cisco DSL Router is the PPPoE client.
(Recommended) A PPPoE client feature was introduced into
Cisco IOS® Software Release 12.1(3)XG. This feature allows the PPPoE client
functionality to be moved to the Cisco DSL Router, which means you do not need
to load PPPoE client software on each PC on your LAN. This feature also allows
multiple PC clients to be connected to the Ethernet interface of the Cisco DSL
Router and share the single PPPoE session between the Cisco DSL Router and the
ISP gateway router.
This implementation includes configuration examples for Network
Address Translation (NAT) overload, NAT Pool, Static NAT, and Dynamic Host
Control Protocol (DHCP) Server.
Cisco IOS Software Release 12.1(3)XG or later is required on the
Cisco DSL Router to support the PPPoE client feature.
Option 2 The PC is the PPPoE client. This option
requires PPPoE client software such as the Windows PPP over Ethernet (WINPoET)
application to be installed on each PC on a local LAN.
