7.2.4 PPPoE or PPPoA
PPPoA (point-to-point protocol over ATM) and PPPoE (point-to-
point protocol over Ethernet) are authentication and connection
protocols used by many service providers for broadband
Internet access. These are specifications for connecting multiple
computer users on an Ethernet local area network to a remote
site through common customer premises equipment, which
is the telephone company’s term for a modem and similar
devices. Users share a common Digital Subscriber Line (DSL),
cable modem, or wireless connection to the Internet. PPPoE
and PPPoA combine the Point-to-Point Protocol (PPP), commonly used in dialup connections, with the Ethernet
protocol or ATM protocol, which supports multiple users in a local area network. The PPP protocol information is
encapsulated within an Ethernet frame or ATM frame.
Before configuring the router, check with your ISP to ensure you have the correct information.
