Well the requesting router could announce the route.  ISC's client
has hooks that allow this to be done.  That is, after all, how
routing is designed to work.  The DHCP server usually is sitting
in a data center on the other side of the country with zero ability
to inject approptiate routes.

The DHCP relay could also have injected routes but that is a second
class solution.

A CPE announcing the route is fine as long as the ISP controls the CPE.

If the CPE is controled by the customer, then the ISP's problems are
similar. They need to find a way to filter the CPE's announcement so
that it can announce only the prefixes delegated to it.

Which is why I mentioned the DHCP relay.

Somewhere back towards the beginnings of this thread there was a
reference to a blog post that complained that they couldn't workout
how to send a git pull request to us.  I've forwarded that to our
dhcp team.  For future reference dhcp-bugs () isc org or dhcp-suggest () isc org
would have been fine places to send the request.  So to the bug
reporting form on isc.org which lets you select if it is bug,
suggestion or a security issue.  There also the general contact
form which would get to the dhcp team after being forwarded a couple
of times.
