Here's what works for my ISP (I'm still on 8.4):
ipv6_enable=YES
ipv6_defaultrouter="fe80::1%em0"
ipv6_ifconfig_em0="fe80::2/64"
ipv6_ifconfig_em0_alias0="2607:f2f8:3080::/64"
ipv6_gateway_enable=YES
I own the /48, but they want their leg to me to be the first /64 of
that. Unlike most ISPs, they're using link-local addresses for that leg
for routing... and they send anything for my /48 to fe80::2 on that leg.
And yes, I'm using the ::0 address as my primary machine address. It
works. :)
$ host red.stonehenge.com
red.stonehenge.com has address 208.79.95.2
red.stonehenge.com has IPv6 address 2607:f2f8:3080::
