Bug description:
[impact]
A bridged interface with static ipv4 address and gateway configuration
will fail to properly add the route via the gateway, leaving the
system without a globally working network.
[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: mtu 1500 qdisc noqueue state DOWN

[Touch-packages] [Bug 1860926] Re: Ubuntu 20.04 Systemd fails to configure bridged network
This happens because the bridge interface comes up with carrier (specifically, with +LOWER_UP interface flag) and begins setting its addresses/routes, but then briefly loses carrier.

Title:
Ubuntu 20.04 Systemd fails to configure bridged network
Status in systemd package in Ubuntu:
Confirmed
Status in systemd source package in Focal:
Confirmed
Bug description:
[impact]
A bridged interface with static ipv4 address and gateway configuration
will fail to properly add the route via the gateway, leaving the
system without a globally working network.
[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
[regression potential]
Not SRU - N/A
[scope]
This is not reproducable on Eoan or Bionic; this is needed only for
Focal.

[Touch-packages] [Bug 1860926] Re: Ubuntu 20.04 Systemd fails to configure bridged network
The following has me wondering if this has partly to do with the presence of containers, VMs and similar items. I upgraded my router to 20.04 a few days before release. (Plain Ubuntu command-line OS on a PC Engines APU1 board) That machine has a bridge network comprising two ethernets and one wifi. I've had no problems with it - it comes up nicely on boot. Whereas I have to use the crontab workaround on my main PC which has a bridge for VMs. I'm not clever enough to imagine why this might be the case, but I thought it might be worth noting. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1860926 Title: Ubuntu 20.04 Systemd fails to configure bridged network Status in systemd package in Ubuntu: Confirmed Status in systemd source package in Focal: Confirmed Bug description: [impact] A bridged interface with static ipv4 address and gateway configuration will fail to properly add the route via the gateway, leaving the system without a globally working network.
