如何在 /etc/systemd/network 中創建虛擬介面？

我正在嘗試為 systemd 創建與以下內容等效的內容。

auto strongswan0
iface strongswan0 inet static
 address 10.0.2.1/24
 pre-up ip link add strongswan0 type dummy

弄清楚了！

cat << "EOF" >> /etc/systemd/network/10-strongswan0.netdev
[NetDev]
Name=strongswan0
Kind=dummy
EOF
cat << "EOF" >> /etc/systemd/network/20-strongswan0.network
[Match]
Name=strongswan0

[Network]
Address=10.0.2.1/24
EOF
