5. (Optional) Initiate reconfiguration of some or all client bindings.

In a routing instance, you can configure dynamic reconfiguration of DHCP clients at the
[edit routing-instances routing-instance-name system services dhcp-local-server] hierarchy
level.

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
