    Configuring Dynamic Reconfiguration Attempts for DHCP Clients

    You can configure how many attempts the local server makes to initiate reconfiguration of the DHCP client by sending forcerenew messages. You can also specify how long the server waits between attempts. By default, eight attempts are made and the initial interval is two seconds.

    Each successive attempt doubles the interval between attempts. For example, if the first value is 2, the first retry is attempted 2 seconds after the first attempt fails. The second retry is attempted 4 seconds after the first retry fails. The third retry is attempted 8 seconds after the second retry fails, and so on. A group configuration takes precedence over a DHCP local server configuration.

    (Optional) To configure DHCP local server reconfiguration behavior for all DHCP clients:

    1. Specify the number of reconfiguration attempts.
      [edit system services dhcp-local-server reconfigure]
      user@host# set attempts 5
    2. Specify the interval between reconfiguration attempts.
      [edit system services dhcp-local-server reconfigure]
      user@host# set timeout 8

    To override the global configuration for a particular group of clients, include the statements at the [edit system services dhcp-local-server group group-name reconfigure] hierarchy level.

    In a routing instance, you can configure reconfiguration attempts for all DHCP clients at the [edit routing-instances <routing-instance-name> system services dhcp-local-server reconfigure] hierarchy level.
