Více VLAN

/etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth0
    iface eth0 inet manual

auto eth0.2
    iface eth0.2 inet static
    address 10.xxx.2.2
    netmask 255.255.255.0

auto eth0.6
    iface eth0.6 inet static
    address 10.xxx.6.2
    netmask 255.255.255.0

auto eth0.7
    iface eth0.7 inet static
    address 10.xxx.7.2
    netmask 255.255.255.0
    gateway 10.xxx.7.1

Nastavení DNS

/etc/systemd/resolved.conf:

[Resolve]
DNS=10.xxx.yyy.1

Tohle je už asi zbytečné:

rm /etc/resolv.conf
ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
systemctl start systemd-resolved.service
systemctl daemon-reload
reboot

Reboot systému není nezbytně nutný, ale je dobré ověřit, že celé nastavení funguje i po restartu.
