This must be done by the delegation router (if you are talking about the DHCPv6 packet itself) - as it is the one that constructs the Advertise and Reply messages to the client.

3GPP system uses these in the above manner i.e. Framed-IPv6-Prefix -> what you put into RA, Delegated-IPv6-Prefix -> what you delegate via DHCPv6. And in this case what was in Framed-IPv6-Prefix goes into OPTION_PD_EXCLUDE.

Hello,

In your opinion, should the copying Framed-IPv6-Prefix -> OPTION_PD_EXCLUDE be rather be done (1) by the RADIUS server (assuming that a new separate hypothetical RADIUS attribute exists) or (2) by the delegating router?
In other words, do you see any benefits in (1)?
