The existing documentation for setting up IPv6 over a tunnel is incorrect.
Specifically: gifconfig is deprecated. Use cloned_interfaces="gif0" instead.

I have filed a PR: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193523
I have the following configuration for my IPv6 tunnel on FreeBSD 9.3 from
Hurricane Electric.
Given:
IPv6 Tunnel Endpoints
Server IPv4 Address: 209.51.x.y
Server IPv6 Address: 2001:470:xx06:9ea::1/64
Client IPv4 Address: 96.245.100.201
Client IPv6 Address: 2001:470:xx06:9ea::2/64
Routed /64: 2001:470:xx07:9ea::/64
My /etc/rc.conf includes
cloned_interfaces="gif0”
ifconfig_gif0="tunnel 96.245.100.201 209.51.x.y mtu 1480”
ifconfig_gif0_ipv6="inet6 2001:470:xx06:9ea::2 2001:470:xx06:9ea::1 prefixlen
128"
ifconfig_em0_ipv6="inet6 2001:470:xx07:9ea:1::1”
ipv6_defaultrouter="2001:470:xx06:9ea::1"
ipv6_gateway_enable=“YES"
rtadvd_enable=“YES”
Comments? Suggestions?
While we're at it, "Routers only store network aggregation addresses in
their routing tables, thus reducing the average space of a routing table
to 8192 entries. This addresses the scalability issues associated with
IPv4, which required every allocated block of IPv4 addresses to be
exchanged between Internet routers, causing their routing tables to
become too large to allow efficient routing."
isn't true and neither is
"These addresses are syntactically indistinguishable from unicast
addresses but they address a group of interfaces. The packet destined
for an anycast address will arrive at the nearest router interface.
Anycast addresses are only used by routers."
No idea what you'd put in place, though :)
