Configuring PPPoE

Overview

Point-to-Point Protocol over Ethernet (PPPoE) extends PPP by transporting PPP frames
encapsulated in Ethernet over point-to-point links.
PPPoE specifies the methods for establishing PPPoE sessions and encapsulating PPP frames over
Ethernet. PPPoE requires a point-to-point relationship between peers instead of a point-to-multipoint
relationship as in multi-access environments such as Ethernet. PPPoE provides Internet access for
the hosts in an Ethernet through a remote access device and implement access control,
authentication, 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 access networks.
For more information about PPPoE, see RFC 2516.

Command and hardware compatibility

Commands and descriptions for centralized devices apply to the following routers:
•
MSR1002-4/1003-8S.
•
MSR2003.
•
MSR2004-24/2004-48.
•
MSR3012/3024/3044/3064.
•
MSR954(JH296A/JH297A/JH298A/JH299A/JH373A)
•
MSR958(JH300A/JH301A)
Commands and descriptions for distributed devices apply to MSR4060 and MSR4080 routers.

PPPoE 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, a session is established between them,
and the PPPoE server provides access control, authentication, and accounting to the PPPoE client.
Depending on the starting point of the PPPoE session, the following network structures are
available:
•
As shown in
Router B). All hosts share one PPPoE session for data transmission without being installed with
PPPoE client software. This network structure is typically used by enterprises.
Figure 10, the PPPoE session is established between routers (Router A and
