Exactly. That's the problem. If you know you can't or aren't very
likely to be able to relay DHCP options to customer's end-nodes, you
don't bother sending them. The myriad of DHCP(v4 and v6) options that
exist that may be useful to an SP are currently of no or very little use
because they can't be conveyed directly to customer's end-nodes across
the CPE boundary.
One could imagine a situation where the CPE makes configures itself with
those options, and by default then transmits them to clients it acts as
a server for. That is probably a different document though.
If the CPE doesn't understand the options, it can't pass them on.
Well of course, yeah.
Only a DHCPv6 relay can effectively convey (relay) options it
doesn't understand because it doesn't actually try to understand them.
I understand how relays work, but thanks. :) You're presuming however
that both end users and SPs would want this behavior, and that both
would want it in spite of it being dramatically different than what is
done currently with IPv4. I don't think either of those is true, but I
don't have research to back it up.
