FWIW I use dhcp6c to get an IPv6 range from my ISP.

My /usr/local/etc/dhcp6c.conf looks like..

interface ng0 {
        send ia-pd 0;
};

id-assoc pd {
        prefix-interface bridge0 {
                sla-id 0;
                sla-len 8;
        };
};

I am using mpd5 for PPPoE and bridge0 is my LAN interface.

My /etc/rtadvd.conf looks like..
# Leaving rltime at the default gives http://www.freebsd.org/cgi/query-pr.cgi?pr=162547
# setting it to 0 prevents it being used as a router. Setting to 1800 (the putative default)
# works..
bridge0:\
        :rltime#1800:\
        :rdnss="xxx":\
        :dnssl="yyy":

where xxx is the IPv6 address of my server and yyy is my domain.

(I'm not sure if the comment regarding rltime is true any more though but it works so I don't touch it ;)
