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.
