Configure PPP Support for AGF

This example describes how to configure the Access Gateway Function (AGF) to support a subscriber using Point-to-Point Protocol over Ethernet (PPPoE) for authentication.


CLI Quick Configuration

To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, and then copy and paste the commands into the CLI at the [edit] hierarchy level.

Step-by-Step Procedure

  1. Configure the dynamic profile for the Point-to-Point Protocol (PPP) subscriber.

  2. Set the access authentication method for the subscriber group to use Non-Access Stratum (NAS) signaling.

  3. Configure the following options for NAS signaling between the AGF and the AMF.

    • Maximum number of outstanding request—The number of unanswered request messages from the AMF.

    • Number of retries—The number of attempts for a registration or deregistration request .

    • Timeout—The duration that the AGF waits for a response from the AMF.

  4. Define the profile with a set of AAA options for the PPP subscriber by performing the following steps:

    • Create the access profile (access-profile) for the subscriber group.

    • Specify the logical-system:routing-instance (LS:RI) that the subscriber session uses for AAA (RADIUS) interactions.
    • Specify the LS:RI where the subscriber interface is placed. In this case, we are using the default routing instance.

    Alternatively, you can create a domain map and apply the domain map to the access profile.

  5. Configure the routing instance.
