    Dear forum,


    I'm trying to trial an MX80 for a BRAS role and am not sure if I need a license for this or not.

    Basically I need the router to:


    - act as pppoe server on specific interfaces

    - authenticate users via chap or pap 

    - assign ppp users the framed-ip-address it receives from the radius server


    No accounting or other features needed.


    Do I need any license for this or not ?


    Thank you.

    Yes, you need a Subscriber Service Management Feature license.

    Hi Alex,


    As you mentioned trial for B-RAS, In Junos releases "prior" to "16.1", MX BNG functionality is enabled at f ull scale (uncapped) features for 30 days upon initial configuration of BNG features. Upon expiration of the 30 day Demo license, subscriber scale is limited to a maximum of 1,000 subscribers.

    Beginning with Junos release 16.1 and all subsequent releases,the 30 day Demo l icense will continue to allow full BNG scale for 30 days. However, after 30 days, the subscriber scale will be limited to 10 subscribers.

    If testing at scale is needed beyond the expiration of the 30 day Demo license grace period, the system must be reinitialized via USB. The typical procedure follows:

    • Copy the configuration and any other needed files off of the router.
    • Reinitialize the router via USB with the desired SW release.
    • Copy the configuration back onto the router to continue testing.

    Note: You require license only when your on production setup. For trail, Testbed/PoC, you dont require license.

    Hi Folks,

    Just my 2 cents on this…


    Software Features That Require Licenses on MX Series Routers Only

    Could you check if your radius server is reachable via source  c0a80a14 ( 

    Do a ping to towards the radius.


    Couple of questions:

    what the JUNOS version? and was your radius server up and running before or is this the first you setting up radius with MX?

    Also check if the radius server is UP or Down?

    BTW, the orginal thread/post is not related to your problem. I would suggest to log a new post on forum.
