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. Read more here https://www.freebsd.org/doc/handbook/network-ipv6.html ifconfig_rl0_ipv6="inet6 accept_rtadv" rtsold_enable="YES" 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.
