I don't think that DHCP servers need necessary know all of the architecture information. They and the relays must be configured appropriately such that the relays provide the DHCP server(s) the correct information.

In the particular cases mentioned, I agree with Ralph. In a either address should work. In b, the site-local is all that can be used.

I think it best we specify that a relay should be configureable to return specific information and if it hasn't been configured, it should use the most "global" information it has (either a global address or site-local). It can't use link-local addresses.

Good questions - here are my answers:

a) Doesn't matter - DHCP server MUST be configured with
    enough architecture information to be able to map
    any address to a link
b) Same answer - DHCP server MUST know site-local
    addresses to do the address->link mapping

Perhaps there's a need to include a few words explaining
about what the DHCP server MUST know about...
