Hi,

   I've tried to establish SIT tunnel to Hurricane Electric, using systemd v214.
It does not work, device do not appear.  I'm concerned about networkd discarding
part of netlink messages, see below.  Original instruction is provided by HE,
rest is my shot at translating it into netdev (nb. manpage wasn't updated when
tunnel features went in).

The se.network file has conf problem. you need to put the interface
name rather tunnel name like eth0/em1


Original instruction:
---------------------
modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.66.80.162 local 109.107.25.67 ttl 255

ip tunnel add he-ipv6 mode sit remote 216.66.80.162 local dev eth0

ip link set he-ipv6 up
ip addr add 2001:470:70:68d::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr


$ cat he.netdev
---------------
[NetDev]
Name=he
Kind=sit

[Tunnel]
Local=109.107.25.67
Remote=216.66.80.162


$ cat he.network
----------------
[Match]
Name=he

you need to supply the interface name here

[Match]
Name=em1 <==========interface name


12: he: <POINTOPOINT,NOARP> mtu 1480 qdisc noop state DOWN mode DEFAULT
group default link/sit 109.107.25.67 peer 216.66.80.162

[Network]
Tunnel=he
Address=2001:470:70:68d::2/64


$ SYSTEMD_LOG_LEVEL=debug /lib/systemd/systemd-networkd
