This is the same for rtadvd.

with rtadvd you can use an empty config file, the conf is made by rc.conf in
this case
for manual way just add :
ifconfig [interface1] 3ffe:4008:1b:1:: prefixlen 64 anycast
ifconfig [interface2] 3ffe:4008:1b:2:: prefixlen 64 anycast
ex :
ifconfig xl0 3ffe:4008:1b:1:: prefixlen 64 anycast
ifconfig fxp0 3ffe:4008:1b:1:: prefixlen 64 anycast
etc
and start rtadvd with interface parameter ex :
rtadvd fxp0 xl0

PS: don't use rtadvd and radvd at the same time! (are you using 2 dhcp
daemon at the same time ?)
PS2: if you're using IPF and DENY by default in the kernel, ensure the
router advertisment pass the rules.
