Cannot connect two ospf-instances over tun-interface

Following commands resulted in similar output on client and server with
different IP-Addresses.

birdc show interfaces:

        10.29.0.1/32 (Primary, opposite 10.29.0.2, scope site)

birdc show ospf interface:

birdc show ospf neighbors: no neighbours.

tcpdump -v -s 0  proto ospf -i tun0

Where server is the name of my server.

In logs I can see only  multiple <TRACE> myOSPF3: HELLO packet sent via
tun0 - messages and once after start initial logs like adding area and
originating lsa for routes from static-protocol.



Now i'm trying to establish ptp-connection for ospf, but in future the
server should run in ptmp mode. I suppose, that there is somethnig wrong
with the IP-Address of peer, since the server has IP-Address 10.29.0.1 and
the client 10.29.0.10. But I declared these IP-Adresses as neighbour in
config file. Maybe there is an issue, that the IP-Addresses are in
/32-network? But unfortunately I cannot change anything in openvpn
settings. Do you have any idea, what I'm doing wrong?
