Abstract
In one embodiment, each of a plurality of devices in a computer network is configured to i) transmit a unicasted dynamic host configuration protocol (DHCP) solicit message to a neighbor device having a route to a border router as an assumed DHCP relay without regard to location of a DHCP server, and ii) operate as a DHCP relay to receive unicasted DHCP solicit messages and relay the solicit message to the border router of the network without regard to location of the DHCP server, and to relay a DHCP reply to a corresponding requestor device.
