Hi Martin,

thanks for your feedback.

The kernel module is loaded (`modprobe vrf` returns code 0). My previous tests had no warnings/errors when the module were missing.

I can successful create vrf entries manually.

Any further ideas?

Hi Lars,

Do you have vrf kernel module available on your system? Depending on
the distribution, the module may have to be explicitly installed.

You'd likely see some warnings/errors in the ovn-controller logs if the
module is missing. You can also try creating vrf manually [0] to see if
it succeeds.

Martin.

Hello everone,
I'm exploring the new dynamic routing feature introduced in OVN
v25.03.
I set up a lab environment similar to the tests found
(
https://github.com/ovn-org/ovn/blob/main/tests/system-ovn.at#L15944).
It includes the following lines:
```
ovn-nbctl lrp-add internet [...] \
     -- set Logical_Router_Port internet-phys
options:dynamic-routing-maintain-vrf=true
```
However, my vrf table (`ip vrf`) is empty. Am I missing something?

Thanks
Lars
