Re: [dhcwg] recommendation on DHCP6 source port numbers

[David Farmer <[e-mail]>]

Ok, it's a little less wordy this time.

Clients receive DHCP messages on UDP (destination) port 546.  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.

Thanks
