link-local address is assigned by default, even with ifconfig_IF_ipv6="up".
root@freebsd:~ # grep -Ev '^[[:space:]]*#|^$' /etc/rc.conf ; ifconfig
em0 | grep -E '^[[:space:]]*inet6' | head -2
hostname="freebsd"
ifconfig_em0="up"
ipv4_addrs_em0="192.168.168.20-24/24"
defaultrouter="192.168.168.1"
ipv6_network_interfaces="em0"
ipv6_defaultrouter="2001:6a0:1cb::ffff"
ifconfig_em0_ipv6="up"
ipv6_addrs_em0="2001:6a0:1cb::1-e/128"
sshd_enable="YES"
dumpdev="NO"
named_enable="YES"
inet6 fe80::a00:27ff:fe02:8371%em0 prefixlen 64 scopeid 0x1
inet6 2001:6a0:1cb::1 prefixlen 128
Of course using "inet6 auto_linklocal" instead of "up" seems a better
way to do it, thank you for this tip.
