Overview

Point-to-Point Protocol over Ethernet (PPPoE) extends PPP by transporting PPP packets encapsulated in

Ethernet over point-to-point links.

PPPoE can provide access to the Internet for the hosts in an Ethernet through a remote access device and

implement access control and accounting on a per-host basis. Integrating the low cost of Ethernet and

scalability and management functions of PPP, PPPoE gained popularity in various application

environments, such as residential networks.

459BPPPoE network structure

PPPoE uses the client/server model. The PPPoE client initiates a connection request to the PPPoE server.

After session negotiation between them is complete, the PPPoE server provides access control and

authentication to the PPPoE client.

The following network structures are available:

• As shown in

2323HFigure 61, the PPPoE session is established between devices (Router A and Router B).

All hosts share one PPPoE session for data transmission without being installed with PPPoE client

dialup software. This network structure is typically used by enterprises.
