Comment 2 for bug 1767849

Hello,

Thank you for reporting this issue and helping make Ubuntu better.

Can you include which Ubuntu release, systemd and netplan package version you were using?

I don't believe there is support in netplan 'routes' for a 'from' field, though I see that it does accept the value

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      addresses:
       - 192.168.3.30/24
      dhcp4: no
      routes:
       - to: 192.168.3.0/24
         via: 192.168.3.1
         table: 101
         from: 10.0.0.1
      routing-policy:
       - from: 192.168.3.0/24
         table: 101

Generates:

root@b1:/run/systemd/network# cat 10-netplan-eth0.network
[Match]
Name=eth0

[Network]
Address=192.168.3.30/24

[Route]
Destination=192.168.3.0/24
Gateway=192.168.3.1
From=10.0.0.1
Table=101

[RoutingPolicyRule]
From=192.168.3.0/24
Table=101

Which then systemd-networkd does complain about a From= in a [Routes] section which isn't supported.

However, I believe you want to use the 'routing-policy' to set the From value for a particular route.

Please confirm if using routing-policy allows you to get the configuration you need. If the configuration can't be achieved with the policy, please include your netplan config as you have it now and an ip route show all to help indicate which route you need to add.

Netplan shouldn't render From= in the [Routes] section for sure.
