[systemd-devel] No default route after "systemctl restart systemd-networkd"

[Gena Makhomed]

Hello, All!

How to fix or workaround this problem with default route?

-------------------------------------------

Configuration file /etc/systemd/network/eth0.network:

[Match]
Name=eth0

[Network]
Gateway=111.111.111.111

[Address]
Address=222.222.222.222/32
Peer=111.111.111.111/32

-------------------------------------------

After server boot:

# ip r

default via 111.111.111.111 dev eth0 proto static
111.111.111.111 dev eth0 proto kernel scope link src 222.222.222.222

And now server is reachable from network.

-------------------------------------------

After executing command "systemctl restart systemd-networkd":

# ip r

111.111.111.111 dev eth0 proto kernel scope link src 222.222.222.222

And now server is unreachable from network.
