The above works.

Unfortunately, that one does not. I do not get any IPv6 addresses

I didn't re-try my original configuration, but I will at another time.

Both of your recommendations failed until I entered ipv6_enable="YES" in
/etc/rc.conf. I did not have this line prior, yet the addresses were
successfully applied, just no default gateway.

Either way, thanks much :)

I will try out your second recommendation again in the future. For now,
problem resolved.
