8.4.2 PPPoE Encapsulation

The EMG2926-Q10A supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF
standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem
(DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection
using PPPoE.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for example Radius).
One of the benefits of PPPoE is the ability to let you 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 individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no
specific configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the EMG2926-Q10A (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the EMG2926-Q10A does that
part of the task. Furthermore, with NAT, all of the LANs' computers will have access.
