But, the routes on the machine are bogus: # ip r default via 10.0.15.253 dev br0 proto dhcp src 10.0.15.109 metric 100 default via 10.0.15.253 dev br0 proto dhcp src 10.0.15.128 metric 100 10.0.14.0/23 dev br0 proto kernel scope link src 10.0.15.128 10.0.15.253 dev br0 proto dhcp scope link src 10.0.15.109 metric 100 10.0.15.253 dev br0 proto dhcp scope link src 10.0.15.128 metric 100 172.16.0.0/24 dev eno1np0 proto kernel scope link src 172.16.0.2 routes with src 10.0.15.109 should have been removed when lease was renewed. I'm not sure if this is a bug in netplan or systemd. This is 18.04, systemd 37-3ubuntu10.21, netplan 0.40.1~18.04.4.
