Configuring Point-to-Point Protocol over Ethernet

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—a J-series Services Router. Hosts share a common digital subscriber line (DSL), a cable modem, or a wireless connection to the Internet. To use PPPoE, you must initiate a PPPoE session, encapsulate Point-to-Point Protocol (PPP) packets over Ethernet, and configure the Services Router as a PPPoE client.

J4300 and J6300 Services Routers with asymmetrical digital subscriber line (ADSL) Physical Interface Modules (PIMs) can use PPPoE over Asynchronous Transfer Mode (ATM) to connect through DSL lines only, not for direct ATM connections.

You can use either the J-Web configuration editor or CLI configuration editor to configure PPPoE.
