Assigning a Dynamic Profile and Routing Instance to a Service Name or ACI/ARI Pair for Dynamic PPPoE Interface Creation

You can create a dynamic PPPoE subscriber interface based on the service name, agent circuit identifier (ACI), and agent remote identifier (ARI) information provided by the PPPoE client during PPPoE negotiation. To do so, you assign a previously configured PPPoE dynamic profile to a named service, empty service, or any service entry in a PPPoE service name table, or to an ACI/ARI pair defined for these services.

Similarly, to specify the routing instance in which to instantiate the dynamic PPPoE subscriber interface, you can assign a previously configured routing instance to a named service, empty service, or any service in a PPPoE service name table, or to an ACI/ARI pair defined for these services.

Observe the following configuration guidelines when you assign a dynamic profile and routing instance to a PPPoE service name table to create a dynamic PPPoE subscriber interface:

  • The dynamic profile and routing instance must already be configured on the router.
  • The dynamic profile or routing instance assigned to the PPPoE service name table overrides the dynamic profile or routing instance assigned to the PPPoE underlying interface on which the dynamic subscriber interface is created.
  • You cannot configure a dynamic profile or routing instance for an ACI/ARI pair already configured with a static interface (by using the static-interface statement). Conversely, you cannot configure a static interface for an ACI/ARI pair already configured with a dynamic profile or routing instance.

Before you begin:

  1. Configure a PPPoE dynamic profile in either of the following ways:
  2. Configure the routing instance in which you want the router to instantiate the dynamic profile.

    For information about configuring routing instances, see the JUNOS Routing Protocols Configuration Guide.

  3. Create the PPPoE service name table on the router.

    See Creating a Service Name Table in the JUNOS Network Interfaces Configuration Guide.

To create a dynamic PPPoE subscriber interface based on the service name and, optionally, associated ACI/ARI pair configured in a PPPoE service name table, do one of the following:

  • Assign a previously configured dynamic profile and routing instance to a named, empty, or any service.
    [edit protocols pppoe service-name-tables table1]user@host# set service premium dynamic-profile premiumProfile routing-instance premiumRI
  • Assign a previously configured dynamic profile and routing instance to the ACI/ARI pair defined for a named, empty, or any service.
