Abstract Abstract
This memo defines a new suboption of the DHCP relay agent information This memo defines a new suboption of the DHCP relay agent information
option that allows the DHCP relay to specify flags for the forwarded option that allows the DHCP relay to specify flags for the forwarded
packet. One flag is defined to indicate whether the DHCP relay packet. One flag is defined to indicate whether the DHCP relay
received the packet via a unicast or broadcast packet. This received the packet via a unicast or broadcast packet. This
information may be used by the DHCP server to better serve clients information may be used by the DHCP server to better serve clients
based on whether their request was originally broadcast or unicast. based on whether their request was originally broadcast or unicast.

Any time a client's DHCP packet is broadcast, a local DHCP relay will Any time a client's DHCP packet is broadcast, a local DHCP relay will
process its request and forward it on to the DHCP server. When the process its request and forward it on to the DHCP server. When the
DHCP relay performs this function, it can be configured to use the DHCP relay performs this function, it can be configured to use the
DHCP relay agent information option to forward additional information DHCP relay agent information option to forward additional information
