Hi

no /etc/network/interfaces ?

Let’s go for it :-)

vim /etc/netplan/01-netcfg.yaml

network:
  version: 2
  renderer: networkd
  ethernets:
    eno1:
      dhcp4: no
      dhcp6: no
      addresses: [192.168.1.2/24, "XXXX:XXXX:XXXX:XXXX::2/64"]
      gateway4: 192.168.1.1
      gateway6: XXXX:XXXX:XXXX:XXXX::1
      nameservers:
        addresses: [1.1.1.1, 1.0.0.1]

here a bridged example

network:
  version: 2
  renderer: networkd
  ethernets:
    eno1:
      dhcp4: no
      dhcp6: no
  bridges:
    br0:
      interfaces: [eno1]
      dhcp4: no
      dhcp6: no
      addresses: [192.168.1.2/24, "XXXX:XXXX:XXXX:XXXX::2/64"]
      gateway4: 192.168.1.1
      gateway6: XXXX:XXXX:XXXX:XXXX::1
      nameservers:
        addresses: [1.1.1.1, 1.0.0.1]

here a bridged example with vlans

network:
  version: 2
  renderer: networkd
  ethernets:
    enp5s0f0:
      dhcp4: no
      dhcp6: no
  vlans:
    vlan302:
      id: 302
      link: enp5s0f0
      dhcp4: no
      dhcp6: no
    vlan412:
      id: 412
      link: enp5s0f0
      dhcp4: no
      dhcp6: no
  bridges:
    br0:
      interfaces: [vlan302]
      dhcp4: no
      dhcp6: no
      addresses: [1.1.1.2/24]
      gateway4: 1.1.1.1
      nameservers:
        addresses: [1.1.1.1, 1.0.0.1]
    br1:
      interfaces: [vlan412]
      dhcp4: no
      dhcp6: no

the spaces are mandatory!

Have fun
