[systemd-devel] VRF - netdev could not be created: Operation not supported

[Martin Belanger]

Hi,

I'm trying to create a vrf netdev, but I get this error message:

systemd-networkd[3818]: vrf-test: netdev could not be created: Operation not supported

It's not clear what "operation not supported" means. Is it because the kernel doesn't support VRF?

Here's some info about my system:

systemd 232
Debian GNU/Linux 9.3 (stretch)
Linux 4.9.30

I created this file /etc/systemd/network/vrf-test.netdev with this content:
[NetDev]
Name=vrf-test
Kind=vrf

[VRF]
TableId=42

Here's the status of systemd-networkd:

# systemctl status systemd-networkd
