Configuring DHCP Duplicate Client Support

You can optionally configure DHCP local server and DHCP relay to include a client subinterface when distinguishing between two clients that have the same MAC address or client ID. The configuration is a global setting for each logical system/routing instance.

To configure DHCP local server to include the client subinterface:

1. Specify that you want to configure DHCP local server.
   [edit system services]user@host# edit dhcp-local-server
2. Configure the optional duplicate client support.
   [edit system services dhcp-local-server]user@host# set duplicate-clients-on-interface

To configure DHCP relay agent to include the client subinterface:

1. Specify that you want to configure DHCP relay agent.
   [edit forwarding-options]user@host# edit dhcp-relay
2. Configure the optional duplicate client support.
   [edit system services dhcp-relay]user@host# set duplicate-clients-on-interface
