PPPoA Overview

If you do not include this field, any access concentrator is acceptable. By
default, no access concentrator is specified.

Identifying PPPoE Services

You can also control which PPPoE session offer the Secure Router OS accepts
by specifying the PPPoE services that are required. From the PPP interface
configuration mode context, enter:
Syntax: pppoe service-name <name>
Replace <name> with a text string of up to 255 characters that identifies the
service-name tags outlined in RFC 2516. If you need to configure the Secure
Router OS to select an access concentrator by service name, your service
provider will give you the service name to enter.
By default, no service names are specified.
PPPoA Overview
Like PPPoE, PPPoA provides several advantages to service providers, includ-
ing the following:
Service providers can control access, track usage, provide services, and
bill for usage on a per-user basis, rather than on a per-site basis.
Service providers can use PPP authentication to ensure that the hosts
requesting access to network services are authorized to use those ser-
vices.
Service providers can build a scalable infrastructure because they can
terminate a large number of PPP sessions through one access
concentrator.
After the ADSL physical connection is established, the router will try to
establish a PPP connection with an access concentrator on the other side of
the DSLAM. The two devices will begin exchanging frames in the customary
sequence for PPP.
PPP peers exchange PPP frames in the order shown in Figure 7-12.
