Netplan / systemd-networkd VLAN отсутствует

Я попытался добавить дополнительный виртуальный интерфейс VLAN, но он не виден в ifconfig.

Netplan Config:
    network:
        version: 2
        renderer: networkd
        ethernets:
            enp0s31f6:
                addresses: [95.216.XX.XXX/32,"2a01:4f9:xx:XXXX::2/64"]
                gateway4: 95.216.xx.xx
                gateway6: fe80::1
                nameservers:
                    addresses: [192.168.122.1,213.133.98.98,213.133.99.99,"2a01:4f8:0:1::add:9999","2a01:4f8:0:1::add:10$
        vlans:
            enp0s31f6.4001:
                id: 4001
                link: enp0s31f6
                addresses: [192.168.3.20/24]
                mtu: 1400

Также networkctl не знает устройство VLAN:

~ # networkctl
IDX LINK             TYPE               OPERATIONAL SETUP
  1 lo               loopback           carrier     unmanaged
  2 enp0s31f6        ether              routable    configured

2 links listed.

Может ли кто-нибудь помочь мне решить мою проблему?
