About

Use this tag for questions related to Point-to-Point Protocol over Ethernet (PPPoE), which is a network protocol for encapsulating PPP frames inside Ethernet frames developed by UUNET, Redback Networks and RouterWare (now Wind River Systems).

PPPoE is used mainly either:

  1. with DSL services where a modem-router connects to the DSL service and sends Internet traffic over PPPoE. Note that the PPPoE over DSL side of things is occasionally referred to as "PPPoE over ATM" (PPPoEoA); or,
  2. when a DSL modem is connected to a (residential) router using an Ethernet cable.
