    Configuring the Router to Maintain DHCP Subscribers During Interface Delete Events

    You can specify a configuration in which the router does not log out a subscriber when the subscriber’s interface is deleted.

    To configure the router to maintain DHCP subscribers when the subscriber interface is deleted:

    1. Specify that you want to configure subscriber management.
      [edit system services]
      user@host# edit subscriber-management
    2. Configure the router to support the maintain-subscriber feature.
      [edit system services subscriber-management]
      user@host# edit maintain-subscriber
    3. Configure the router to enable the maintain-subscriber feature when an interface-delete event occurs.
      [edit system services subscriber-management maintain-subscriber]
      user@host# set interface-delete

    In a routing instance, you can configure subscriber management at the [edit routing-instances routing-instance-name system services subscriber-management] hierarchy level.
