Abstract: In an embodiment, an electronic digital data packet router performs receiving a DHCP initiation message on a particular interface among a plurality of network interfaces; modifying the DHCP initiation message by adding a particular DHCP option that signals a DHCP server to provide router configuration data, resulting in a modified DHCP initiation message; relaying the modified DHCP initiation message to the DHCP server; receiving, from the DHCP server, a DHCPOFFER message that comprises the particular DHCP option containing configuration data; configuring the router using the configuration data; relaying the DHCPOFFER message without the particular DHCP option on the particular interface toward another data packet router.
