Yes systemd is now at 245.4-4ubuntu3.1 and the interface does come up at boot.
Note my config is also now using the macaddress parameter as mentioned by another commenter above, which may have effected the result.

[test case] On a Focal system, remove all network configuration and create this netplan: network: version: 2 renderer: networkd ethernets: enp4s0: dhcp4: false bridges: br0: interfaces: [enp4s0] dhcp4: no addresses: [192.168.0.4/24] gateway4: 192.168.0.1 nameservers: search: [mydomain] addresses: [192.168.0.1,192.168.0.2,192.168.0.3] Replace the interface name 'enp4s0' with the actual interface name on the test system. Reboot the system, and check the route to the gateway, which will be missing: root@lp1860926-f:~# ip r 192.168.0.0/24 dev br0 proto kernel scope link src 192.168.0.4 The route is expected to be present, e.g.: ubuntu@lp1860926-e:~$ ip r default via 192.168.0.1 dev br0 proto static 192.168.0.0/24 dev br0 proto kernel scope link src 192.168.0.4 [test case, pre-focal] same netplan as above, but remove ethernets: section. Reboot, and the bridge should have its address and route: ubuntu@test-e:~$ ip a show br0 3: br0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000 link/ether 56:11:da:23:bb:93 brd ff:ff:ff:ff:ff:ff inet 192.168.0.4/24 brd 192.168.0.255 scope global br0 valid_lft forever preferred_lft forever ubuntu@test-e:~$ ip r default via 192.168.0.1 dev br0 proto static linkdown 192.168.0.0/24 dev br0 proto kernel scope link src 192.168.0.4 linkdown add and remove carrier, by adding and removing a slave interface: ubuntu@test-e:~$ sudo ip l set dev ens3 master br0 up ubuntu@test-e:~$ ip a show br0 3: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 56:11:da:23:bb:93 brd ff:ff:ff:ff:ff:ff inet 192.168.0.4/24 brd 192.168.0.255 scope global br0 valid_lft forever preferred_lft forever inet6 fe80::5411:daff:fe23:bb93/64 scope link valid_lft forever preferred_lft forever ubuntu@test-e:~$ sudo ip l set dev ens3 nomaster the bridge no longer has its address after losing carrier: ubuntu@test-e:~$ ip a show br0 3: br0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000 link/ether 56:11:da:23:bb:93 brd ff:ff:ff:ff:ff:ff inet6 fe80::5411:daff:fe23:bb93/64 scope link valid_lft forever preferred_lft forever [regression potential] Any regression would likely involve incorrectly configured network after an interface carrier gain/loss. [scope] This is needed for Focal, Eoan, and Bionic. While this only reproduces at boot for Focal, the general loss of configuration on carrier loss even when ConfigureWithoutCarrier=true is reproducable on all releases except Xenial, which does not have the ConfigureWithoutCarrier= parameter.
