description |
Configuring "/etc/netplan/01-netcfg.yaml" with an anonymous bridge seems to require running "ip link set dev br0 up" to bring the bridge up after boot. A bridge configured with an IP address is automatically up after boot.
This is only a problem if you want an anonymous bridge which comes up automatically after boot. For example, if you preferred to isolate host traffic from your autostarting virtual machine traffic.
Configuration that results in the bridge being down after boot:
network:
version: 2
renderer: networkd
ethernets:
enp22s2:
dhcp4: yes
enp22s3:
dhcp4: no
bridges:
br0:
interfaces: [enp22s3]
dhcp4: false
parameters:
stp: false
forward-delay: 0
Enabling DHCP results in a bridge that is automatically up after boot:
network:
version: 2
renderer: networkd
ethernets:
enp22s2:
dhcp4: yes
enp22s3:
dhcp4: no
bridges:
br0:
interfaces: [enp22s3]
dhcp4: true
parameters:
stp: false
forward-delay: 0
Setting a static IP address results in a bridge that is automatically up after boot:
network:

renderer: networkd
ethernets:
enp22s2:
dhcp4: yes
enp22s3:
dhcp4: no
bridges:
br0:

[Impact]
Netplan users setting up bridges.
[Test cases]
1) Add a new bridge configuration in netplan yaml, without an IP address set:
[...]
bridges:
br0:
interfaces: [ interface ]
dhcp4: false
parameters:
stp: false
forward-delay: 0
[Regression potential]
Possible regression scenarios might be for a configured bridge not to come up / not be created or added by systemd-networkd when the network is configured; or for a bridge to be configured with addresses that should not be present (ie. dhcp when it is not enabled, or link-local address when not configured).
