Provisioning Ppp Pta Session; Creating Pppoe Profiles - Cisco ASR 9000 Series Configuration Manual

Establishing Subscriber Sessions

Provisioning PPP PTA Session

In a PPP Termination and Aggregation (PTA) session, the PPP encapsulation is terminated on BNG. After it
is terminated, BNG routes the traffic to the service provider using IP routing. A typical PTA session is depicted
in this figure.
Figure 6: PTA Session
PPPoE session configuration information is contained in PPPoE profiles. After a profile has been defined, it
can be assigned to an access interface. Multiple PPPoE profiles can be created and assigned to multiple
interfaces. A global PPPoE profile can also be created; the global profile serves as the default profile for any
interface that has not been assigned a specific PPPoE profile.
The PPP PTA session is typically used in the Network Service Provider (retail) model where the same service
operator provides the broadband connection to the subscriber and also manages the network services. The
process of provisioning a PPP PTA session involves:
• Creating a PPPoE profile for PPPoE session. See,
• Creating dynamic template that contains the various settings for the PPPoE sessions. See,
• Creating policy-map to activate the dynamic template. See,
• Enabling subscriber creation, and apply the PPPoE profile and service-policy on the access interface.

Creating PPPoE Profiles

Perform this task to create PPPoE profiles. The PPPoE profile will later be applied to an access interface.

The subscriber creation function must be explicitly enabled on BNG. Unless this function is enabled,
the system will not attempt subscriber classification. As a result, the packets get forwarded based on the
incoming interface mode.
