Should we also make it recommended to use the designated port as the source port? With the may to send arbitrary port and a must to accept an arbitrary port? O.

Servers and relay agents receive DHCP messages on UDP (destination) port 547. Clients, servers, and relay agents MAY send DHCP messages from any UDP (source) port they are allowed to use, including their designated destination ports. Nevertheless, regardless of the source port used, DHCP messages MUST be sent to their designated destination ports.

Nevertheless, regardless of the source port the client uses, the server or relay agent MUST send traffic to the designated destination port of the client. And vice versa, regardless of the source port used by the server or relay agent, the client MUST send traffic to the designated destination port of the server or relay agent.

It’s a lot more important to have the specification clear and unambiguous. I think it has been shown that it isn’t. Happy with whatever solution there is consensus for, but the ambiguity has to be resolved I think.
