SYSTEMD_LOG_LEVEL=debug of systemd-networkd

Setting up a bridge with systemd-networkd does not works for me. I can not
reach other hosts on the same network (i.e. ping the default gateway).
Doing things manually with iproute2 works fine.
The output of "ip addr" looks same in both cases.


-- br0.netdev --
[NetDev]
Name=br0
Kind=bridge
----

-- br0.network --
[Match]
Name=br0

[Network]
Address=192.168.0.77/24
Gateway=192.168.0.1
----

-- enp0s16.network --
[Match]
Name=enp0s16

[Network]
Bridge=br0
----

This is are the steps I am doing for the same thing, that works:
----
ip link add name br0 type bridge
ip addr add 192.168.0.77/24 broadcast + dev br0
ip link set dev enp0s16 master br0
ip link set dev br0 up
ip link set dev enp0s16 up
ip route add default via 192.168.0.1
----


In both cases the output of "ip addr" is:

----
2: enp0s16: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
master br0 state UP group default qlen 1000
    link/ether 00:17:31:bb:44:19 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::217:31ff:febb:4419/64 scope link
       valid_lft forever preferred_lft forever
8: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UP group default
    link/ether 00:17:31:bb:44:19 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.77/24 brd 192.168.0.255 scope global br0
       valid_lft forever preferred_lft forever
    inet6 fe80::217:31ff:febb:4419/64 scope link
       valid_lft forever preferred_lft forever
----

and output of "bridge fdb":
----
01:00:5e:00:00:01 dev enp0s16 self permanent
33:33:00:00:00:01 dev enp0s16 self permanent
33:33:ff:bb:44:19 dev enp0s16 self permanent
00:19:3e:ea:c5:54 dev enp0s16 vlan 0
00:21:29:98:d4:f3 dev enp0s16 vlan 0
00:17:31:bb:44:19 dev enp0s16 vlan 0 permanent
----

If after start networkd, I set br0 to promisc executing "ip
link set br0 promisc on", network works fine, but of course now "br0"
shows PROMISC under "ip link".


OS: Arch Linux (x86_64) running on Linux 3.10.50, systemd-215-4
