Hello Dawid, I fought with this one for some time, I did get it working with OpenVPN but threw it out in favor of Tinc in the end… Here is are the couple gotchas I ran into for OenVPN; 1. Use tap instead of tun 2. Ensure you have an interface (show interfaces) If you do not have interfaces on the “client side” add; protocol device { scan time 10; } The tricky part after getting OSPF online was actually getting anything to route… but that is for later (; Cheers, Mike -- Michael McConnell WINK Streaming; email: michael@winkstreaming.com toll free: 877-GO-4-WINK x 7400 direct: +1 312 281-5434 cell: +506 8706-2389 skype: wink-michael web: http://winkstreaming.com

Here my configuration (client):

tcpdump -v -XX proto ospf -i tun0 (confirmation, that hello messages are sent and received) :

The server is using similar configuration. It differs only by IP(10.29.0.1) and router-ID.
2018-03-29 13:37 GMT+02:00 dawid k <tookie009smieci@gmail.com <mailto:tookie009smieci@gmail.com>>: I'm trying to set up pretty simply configuration consisting of two linux machines connected over tun-interface created by OpenVPN.
The VPN-connection is working fine - I can send data over this interface. Now I installed bird and configured ospf on both devices. I can see that both bird instances are sending hello packets on tun-interface however no one of them is getting the message.
I can see with tcpdump, that every device is getting the hello-message. However they are not forwarded to bird or bird just ignores them.
I tried my setup over cabel with eth0-interface and everything is working fine. Right now every machine is advertising just one example static network. I will focus on correct advertising later after I connect those two instances.
The tun0 interface is working in type ptp and the netmask is 255.255.255.255. Do you have any idea what's wrong?
Thanks for every input, tookie009
