Configuring network interfaces

Configure PPP over Ethernet

PPP over Ethernet (PPPoE) is a means of establishing a PPP connection over the top of an Ethernet
connection. The implementation provided is compliant with RFC 2516, "A Method for Transmitting PPP
Over Ethernet". A typical application would be to allow non-PPPoE enabled devices to access Internet
services where the connection to the Internet is provided by an ADSL bridge device.
É
Web
There is no dedicated web page for configuring the router to use PPPoE. Instead, there are several
parameters on other web pages you must use together to establish a PPPoE connection over the
appropriate Ethernet interface. In particular, the following configuration pages and parameters are
important.
1. Go to the Configuration > Network > Interfaces > Advanced > PPP n-n > PPP n pages for
the PPP connections that require PPPoE.
2. Set the following parameters:
As a minimum requirement, set the Username and Password parameters.
n
The setting This PPP interface will use x,y defines the physical Ethernet interface
n
over which the PPPoE session will operate. In most cases, this physical interface is
PPPoE 0 (for Ethernet 0). The fact that you have selected PPPoE 0 as the physical
interface for operation with PPP automatically enables PPPoE mode. If the router uses
another Ethernet instance, for example, Eth 1, you must select PPPoE 1 to ensure the
router uses the correct MAC address. This parameter value is in the format 0 or blank
for port 0, 1 for port 1, 2 for port 2 etc.
If necessary, go to the page Configuration > Network > Interfaces > Advanced > PPP
n
n-n > PPP n > Advanced and set the Enable "Always On" mode of this interface
parameter to On to configure the router so that it will attempt to renegotiate the PPP
link should it go down for any reason.
PPP negotiation: Initialize the advanced PPP options on this page as required by your
n
ISP.
Desired Local MRU and Desired Remote MRU: Set to 1492.
n
Request Local ACFC and Request Remote ACFC: Set to No.
n
Request Local PFC and Request Remote PFC: Set to No.
n
Desired Local ACCM and Desired Remote ACCM: Set to 0xffffffff.
n
3. Click Apply on each PPP settings page when done.
Command line
There are no specific PPPoE commands available to the user via the text command interface. Use the
appropriate ppp commands to set the required options.
