  • 1.  Install subscriber routes on more than one subscriber

    Posted 03-19-2021 07:22
    We use a MX204 for access services (PPPoE) as a BNG router.

    The authentication works with radius and the parameters Framed-IP and Framed-Routes are set which works fine.
    When a different user with the same Framed-IP as a existing subscriber session logs in, the session is not set up. That is totally fine and prevents human errors assigning the same IP twice (which is not a must).

    However, the same happens with Framed-Routes - even with different metrics, so the PPPoE Session is not set up because the route already exists for a subscriber.
    If that works would be super helpful for failover scenario but also for load balancing across subscriber sessions.

    Is there a "knob" allowing the same framed route to be installed on different subscriber sessions (and also allow the session to come up)?

    thanks for ideas!

    I found an answer already.

    This scenario described the fallback scenario:
