3.3.2 PPPoE Encapsulation

The Prestige supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft standard (RFC
2516) specifying how a personal computer (PC) interacts with a broadband modem (i.e. DSL, cable, wireless,
etc.) connection.
For the service provider, PPPoE offers an access and authentication method that works with existing access
control systems (e.g., Radius). For the user, PPPoE provides a login & authentication method that the
existing Microsoft Dial-Up Networking software can activate, and therefore requires no new learning or
procedures for Windows users.
One of the benefits of PPPoE is the ability to let end users access one of multiple network services, a function
known as dynamic service selection. This enables the service provider to easily create and offer new IP
services for specific users.
Operationally, PPPoE saves significant effort for both the end user and ISP/carrier, as it requires no specific
configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the Prestige 314 rather than individual PC's, the machines on the LAN
do not need PPPoE software installed since the P314 does that part of the task. Furthermore, with NAT, all
of the LAN's machines will have access.
If you enable PPPoE in Menu 4, you will see the next screen. For more information on PPPoE, please see the
Appendices.
