Public bug reported:
Using ubuntu 22.04 I try to assign the two IP addresses
`192.168.200.100` and `169.254.1.0` to the ethernet device
`enx00e04c680202`. Following [this tutorial][1] and [this answer][2] I
created a file `/etc/netplan/01-network-config_home.yaml` with the
following content:
network:
version: 2
renderer: NetworkManager
ethernets:
enx00e04c680202:
addresses:
- 192.168.200.100/24
- 169.254.1.100/24
routes:
- to: default
via: 192.168.200.220
metric: 200
routes:
- to: default
via: 169.254.1.220
metric: 300
and applied the changes using the command
sudo netplan apply
I checked the configuration with the command `ip address show dev enx00e04c680202`, but it seems only one address is shown:
3: enx00e04c680202: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 00:e0:4c:68:02:02 brd ff:ff:ff:ff:ff:ff
inet 192.168.200.100/24 brd 192.168.200.255 scope global noprefixroute enx00e04c680202
valid_lft forever preferred_lft forever
But the other configured address `169.254.1.0` seems to be working; I am
able to connect to a device with the IP address 169.254.1.0.
However, when I add an IP address to that adapter `enx00e04c680202`
using the following command
sudo ip addr add 169.254.1.100/24 dev enx00e04c680202
then I see the following output of the command `ip address show dev
enx00e04c680202`:
3: enx00e04c680202: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 00:e0:4c:68:02:02 brd ff:ff:ff:ff:ff:ff
inet 192.168.200.100/24 brd 192.168.200.255 scope global noprefixroute enx00e04c680202
valid_lft forever preferred_lft forever
inet 169.254.1.100/24 scope global enx00e04c680202
valid_lft forever preferred_lft forever
This is what I would expect in both cases.
It has been suggested that this is a bug.
