Overview of PPPoE
PPPoE describes the method used to set up PPPoE sessions and encapsulate PPP datagram over the Ethernet. These functions require a point-to-point (P2P) relationship between the peers instead of the multi-point relationships that are available in the Ethernet and other multi-access environments.
Definition
PPPoE is the short for Point-to-Point Protocol over Ethernet. It connects a network of hosts formed by the Ethernet to a remote access device to gain access to the Internet. It allows you to perform access control and accounting on a per-host basis. As it is highly cost-effective, PPPoE is widely adopted, for example, in network construction for residential areas.
Objective
PPPoE performs the following functions when multiple users access a server using PPP links:
Provides cost effective access services for users and allows a few or no configuration changes. An Ethernet is the most cost-effective networking mode.
Allows a service provider to connect multiple hosts at a remote site to the same access server and supports access control and accounting functions in a way similar to dial-up services using Point-to-Point Protocol (PPP).
Although PPP is widely used, it does not apply to an Ethernet. Therefore, the PPPoE technology was introduced. PPPoE is an extension to PPP and applies PPP to an Ethernet.
PPPoE enables a bridged access server to connect multiple hosts on a network to a remote access server.
A FW currently supports IPv4 PPPoE server and client functions and IPv6 client functions.
