While there is a DHCPv6 protocol, it doesn't do quite the same things
as DHCP for v4 does. And most IPv6 networks use a combination of
router soliciation and prefix auto-configure on the interfaces, as
this was the original specification that IPv6 networks did.

If you are in a network that actually uses stateful DHCPv6 assignments
(rare), there are various dhclient options to make it work, although I
don't have such a setup to tell you what is needed.
And DHCPv6_PD is something else altogether different used by many ISP CPE if
that is what you are trying to do. I'd see what pfsense does to properly set that up.
