Ubuntu – how to configure dumthe interface with netplan on ubunty 17.10

networkingUbuntu

how do I configure dummy interface with netplan?

I could manually configure them with systemd:

Configure the dummy interface to setup at boot:
edit /etc/systemd/network/dummy0.netdev
add

[NetDev]
Name=dummy0
Kind=dummy

edit /etc/systemd/network/dummy0.network
add

[Match]
Name=dummy0

[Network]
Address=169.254.1.1/32

how do I get the same result with netplan?

There is a bug: https://bugs.launchpad.net/netplan/+bug/1773997

After it is fixed you should be able to create /etc/netplan/02-dummy.yaml with content:

network:
  version: 2
  renderer: networkd
  bridges:
    dummy0:
      dhcp4: no
      dhcp6: no
      accept-ra: no
      interfaces: [ ]
      addresses:
        - 169.254.1.1/32

And execute

( umask 0022; netplan apply; );
