Bridge wlan0 to br0 resulting in error

Hi guys,

im running vyos in a vm and i’m trying to bridge wlan0 in client (station) mode to my attached usb eth1 via br0.

When i try to commit wlan0 to br0 i get the following error.

vyos@vyos# commit
[ interfaces bridge br0 ]
VyOS had an issue completing a command.

returned (err):
Error: Device does not allow enslaving to a bridge.

Is there a solution to this?

Or probably a better way to reach the final go:
The final goal is to provide local lan access to my bare metal host which cant handle wifi connections.
Locallan - Vyos br0 (wlan0,eth1) - Unraid server eth0

Thx hixquix

This looks to me as though the br0 interface is already a bridge.
Could you post the set commands you’re using to set this up?

i used the tab function for auto completion.

This is what i did:

set interface bridge br0 address dhcp

set interface bridge br0 member eth1
set interface bridge br0 member wlan0
