Routes with interface inactive
Hello everybody,


I'm trying a pretty simple config using 3 routers, 2 ospf areas and I want to propagate routes from one area to another. R1 is connected directly with R2 (which is ABR) in area 0, and R2 is connected through OpenVPN with R3 in area 1.
Everything works fine, except the fact that routes from R3 looks like this:

#sh ip ro
[..]
O   172.24.172.0/24 [110/21] via 10.111.0.1, tun0 inactive, 03:25:15
O   172.24.200.0/24 [110/21] via 10.111.0.1, tun0 inactive, 03:25:15
O   172.24.255.0/24 [110/21] via 10.111.0.1, tun0 inactive, 03:25:15
O   192.168.1.0/24 [110/20] via 10.111.0.1, tun0 inactive, 03:29:19
O   192.168.2.0/24 [110/21] via 10.111.0.1, tun0 inactive, 03:25:15
O   192.168.10.0/24 [110/1] via 10.111.0.1, tun0 inactive, 03:25:14
O   192.168.11.0/24 [110/1] via 10.111.0.1, tun0 inactive, 03:25:14

My problem is that these routes aren't inserted in kernel, I guess because tun0 appears inactive. But tun0 from R3 is active and participate in ospf process, it is connected with tun0 from R2 (OpenVPN interfaces).
I don't want to make this message too long with unnecessary information, so if you need more details about some things, I will wrote them. One simple question is what "tun0 inactive" message means and at which parameters should I look to understand where could be a misconfiguration.

P.S. I have tested identical configuration with 3 virtual machines and I didn't see this problem.

Thank you for your time.
