Hi,

> We're deploying in managed CPE, so the hint will for sure not change anything.  I agree it is also "just" a hint, but the req in the RFC says you SHOULD flag "too small" and it's exactly that part which is not ok, not the fact that you should sent a hint or anything.

I really can't see the point of this.

Your CPE is configured to have 2 different LAN zones, and 1 WiFi zone.

IETF says "a /64 per routed interface".  So you count 1..2..3 and request
a /62 or /60.

The ISP gives you a /63.  You count again "1..2...oops".

You log "to number all (3) interfaces a /62 has been requested by DHCP-PD
and only a /63 has been delegated.  Interface 3 (WiFi) will not receive
an IPv6 address, we're sorry".


Now which is the step that you are unable to do?

(Maybe I'm daft, or it's because I've never worked for a mass marked CPE
producer, but this really seems straightforward and easy to implement to
me...)
