IETF RFC 5010
The Dynamic Host Configuration Protocol Version 4 (DHCPv4) Relay Agent Flags Suboption
|Publication Date:||1 September 2007|
This memo defines a new suboption of the Dynamic Host Configuration Protocol (DHCP) relay agent information option that allows the DHCP relay to specify flags for the forwarded packet. One flag is defined to indicate whether the DHCP relay received the packet via a unicast or broadcast packet. This information may be used by the DHCP server to better serve clients based on whether their request was originally broadcast or unicast.
