Re: Cannot connect two ospf-instances over tun-interface

Hello, I got the server to work. The issue was, that I didn't disable iptables correct. Now two client and the server are exchanging own routes. I connected to one client another one over a router and the router is connected to the ospf-network as well. But somehow I cannot contact the new clien

Hmmm ... will try it on my own network some time this week. If I don't send any report until Monday (April 9th), please ping me. M. On 04/04/2018 11:35 AM, dawid k wrote: > > > 2018-04-04 10:59 GMT+02:00 Jan Maria Matejka >: > > Hello, > > please could you

Re: Cannot connect two ospf-instances over tun-interface

Hello, please could you enable 'debug all' for the ospf protocol at server? It should tell you whether it receives the packets and what is it doing with them. OpenVPN in TUN mode does quite strange things with routing. Have you tried routing by static routes first (to see whether it works or not)

Re: Cannot connect two ospf-instances over tun-interface

Hi Chris, Thank you for your advice, I got a little bit forward. I expended my topology with another pc - another vpn client - and I got these two vpn clients working, but somehow I cannot get the server to work properly. The server remains always in state Init/Other. I can see with tcpdump, th

Cannot connect two ospf-instances over tun-interface

[re-sending to the list with the correct From address] Hi, You should be able to do this with 'topology subnet' on your server end. It doesn't work with net30 (the default) or p2p, but I can confirm that OSPFv2 for IPv4 works in broadcast mode with 'topology subnet'. I think there are issues wit

Re: Cannot connect two ospf-instances over tun-interface

Therefore I tried running ospf in broadcast mode as well, but then it changed automatically: myOSPF3: Cannot use interface tun0 as broadcast, forcing ptp I tried the tap-Interface and it's working (or at least the neighbours were detected) but as said, my system has to use tun and I cannot chang

Re: Cannot connect two ospf-instances over tun-interface

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 t

Cannot connect two ospf-instances over tun-interface

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
