Configuring Dynamic Reconfiguration of DHCP Clients to Avoid Extended Outages Due to Server Configuration Changes

The DHCP local server can initiate reconfiguration of its clients to avoid extended outages because of server configuration changes. In addition to requesting that the DHCP local server initiate reconfiguration, you can specify the reconfiguration behavior.

To configure dynamic reconfiguration of DHCP clients:

  1. Enable dynamic reconfiguration with default values for all clients.
    [edit system services dhcp-local-server]
    user@host# set reconfigure
  2. (Optional) Override the global configuration for a particular group of clients.
    [edit system services dhcp-local-server group-name]
    user@host# set reconfigure
  3. (Optional) Configure how the server attempts reconfiguration.

    See Configuring Dynamic Reconfiguration Attempts for DHCP Clients.

  4. (Optional) Configure the response to a failed reconfiguration.

    See Configuring Deletion of the Client When Dynamic Reconfiguration Fails.

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

    See Requesting DHCP Local Server to Initiate Reconfiguration of 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.
