The client gets delegated a prefix, but there is no routing information in the table afterward. The prefix delegated to the client should also be routed to the client.

With ISC there is a script which scrapes the data and handles the route, I don't see it running when Kea is enabled:

/usr/local/sbin/dhcpleases6 -c /usr/local/bin/php-cgi -f /usr/local/sbin/prefixes.php -l /var/dhcpd/var/db/dhcpd6.leases

Will need to hook into Kea run_script support that was added for Unbound integration to install/deinstall routes as IA_PD leases are issued and expired.
