IPv6 configuration is still a work in progress. Currently, you can't
enable and auto-configure IPv6 *after* the initial boot. The reason for
this is that the IPv6 configuration subroutines require all IPv6 interfaces
to have a link-local address first. However, the rc.d/auto_linklocal script
is executed before all the networking stuff and if IPv6 is not enabled it sets
a sysctl(8) variable to prevent the IPv6 subsystem in the kernel from
assigning link-local addresses. If you don't want to reboot, then you
have to assign the link-local addresses yourself with ifconfig(8) and then
run rc.d/network_ipv6 (should work in theory, haven't tried it).
I've found a way:
# sysctl net.inet6.ip6.auto_linklocal=1
# ifconfig em0 down up
will assign link-local address to interface.
after all required interfaces have link-local addresses,
run /etc/rc.d/network_ipv6 start and all will be set ! :)
