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
