The Point-to-Point Protocol over Ethernet (PPPoE) connects multiple hosts on an Ethernet LAN to a remote site through a single customer premises equipment (CPE) device. Hosts share a common digital subscriber line (DSL), a cable modem, or a wireless connection to the Internet.
A J-series Services Router can be configured as the CPE device for PPPoE connections. To use PPPoE, you must configure the Services Router as a PPPoE client, encapsulate PPP packets over Ethernet, and initiate a PPPoE session.

Note: J4300 and J6300 Services Routers with asymmetrical DSL (ADSL) Physical Interface Modules (PIMs) and symmetrical high-speed DSL (SHDSL) PIMs can use PPPoE over Asynchronous Transfer Mode (ATM) to connect through DSL lines only, not for direct ATM connections. For information about configuring ADSL and SHDSL interfaces, see Configuring ATM-over-ADSL Interfaces and Configuring ATM-over-SHDSL Interfaces. |
An M120 Internet router can be configured as a PPPoE access concentrator server. To configure a PPPoE server on an M120 Ethernet logical interface, specify PPPoE encapsulation, include the pp0 statement for the pseudo PPPoE physical interface, and include the server statement in the PPPoE options under the logical interface.
|
Note: PPPoE encapsulation is not supported on an M120 router on an ATM2 IQ interface. |
On the J-series Services Router, PPPoE establishes a point-to-point connection between the client (the Services Router) and the server, also called an access concentrator. Multiple hosts can be connected to the Services Router, and their data can be authenticated, encrypted, and compressed before the traffic is sent to the PPPoE session on the Services Router’s Fast Ethernet or ATM-over-ADSL interface. PPPoE is easy to configure and enables services to be managed on a per-user basis rather than on a per-site basis.
