# ip dhcp-external recreate-subscriber-interface

#### Syntax

[ no ] ip dhcp-external recreate-subscriber-interface

#### Release Information

Command introduced in JunosE Release 9.2.0.

#### Description

Configures the DHCP external server application to delete and re-create the existing dynamic subscriber interface after a bound DHCP client extends its IP address lease by restarting the DHCP discovery process on its primary IP interface instead of by initiating the DHCP renewal process on its dynamic subscriber interface. This command is specific to a virtual router. The no version restores the default behavior, which preserves the dynamic subscriber interface after a bound client restarts the discovery process on its primary IP interface.

#### Mode
