    DHCP Local Server Handling of Client Information Request Messages

    Dynamic Host Configuration Protocol (DHCP) clients that already have externally provided addresses might solicit further configuration information from a DHCP server by sending a DHCP information request that indicates what information is desired. By default, DHCP local servers ignore any DHCP information requests that they receive. You can override this default behavior to enable processing of these messages. Include the process-inform statement at the [edit system services dhcp-local-server overrides] hierarchy level.

    In a routing instance, include the process-inform statement at the [edit routing-instances routing-instance-name system services dhcp-local-server overrides] hierarchy level.

    The information requested by the clients has typically been configured with the dhcp-attributes statement for an address pool defined by the address-assignment pool pool-name statement at the [edit access] hierarchy level.

    When you enable processing of DHCP information requests, you can optionally specify the name of the pool from which the local server retrieves the requested configuration information for the client.

    DHCP local server responds to the client with a DHCP acknowledgment message that includes the requested information—if it is available. No subscriber management is applied as a result of the DHCP information request message.
