Public bug reported:
In the old /etc/network/interfaces I could define a virtual interface:
auto eth0
iface eth0 inet static
address aaa.aaa.aaa.aaa
netmask 255.255.255.0
gateway aaa.aaa.aaa.1
auto eth0:0
iface enp7s0f0:0 inet static
address bbb.bbb.bbb.bbb
netmask 255.255.255.0
This is not possible to achieve with the netplan. The only exisiting
posibilities are either to create a VLAN, which may be not an option in
some networks where you have no access to other hosts, or to define both
addresses for one interface:
network:
version: 2
renderer: networkd
ethernets:
eth0:
addresses: [aaa.aaa.aaa.aaa/24, bbb.bbb.bbb/24]
gateway4: aaa.aaa.aaa.1
This solution is not optimal either, because configuring iptables or
some services may require specific interface name for a single network.
It should be possible to add the same physical interfaces with different
networks and different alias names.
