IPoE configuration problem on MX204

  • 1.  IPoE configuration problem on MX204

    Posted 01-03-2023 10:03
    I have configured IPoE on MX204 according to the juniper subscriber configuration guidelines with the following link:
    [Subscriber Management] Configuration Example - end-to-end IPv6 or Dual-Stack IPoE Subscriber (
    however, while attempting to commit, I received this error message:  commit check
    [edit interfaces demux0]
    'unit "$junos-underlying-interface-unit"'
    Can't get unit # for ifd demux0
    error: configuration check-out failed

    Does anybody has any good solution for that or any other way to configure IPoE for our Subscriber instead of PPPoE?
