PC connected via VPN links with tincd.<br>
<br>
IP packets with destination 10.195.228.128 loop between routers<br>
10.179.155.153 and router 10.179.196.113 The loop is stable over time.<br>
I can SSH in the routers and see the weird entries in the routing<br>
table that cause the loop.<br>
<br>
Configuration of the nodes is generated with this script:<br>

<br>
(this should explain why the etx values are all "ones" with a little<br>
introduced error.)<br>
<br>
How can I debug this problem ? I really have never seen anything like<br>
this before and I have no idea how to debug the problem.<br>
<br>
Looks like dot draw plugin shows the links to 10.195.228.128 but<br>
routers do not forward to that link. Resetting OLSR with the same<br>
configuration on 10.179.155.153 and 10.179.196.113 fixed the routing<br>
tables.<br>
