every 5 minutes ospf routing works or not

Fri Jun 10, 2011 12:20 pm

Hello,

I have this problem, have my backbone network set up with ospf. Recently we opened new office and i needed to interconnect it with main network. I have created IPIP with IPSec tunnel with dynamic routing. For dynamic routing i have used OSPF again. Created new instance, new area and added a network. The ospf worked just fine, for 5 minutes and then went down again. This is repeating constantly. The only logs i am getting are:
10:01:51 route,ospf,info OSPFv2 neighbor 10.0.0.2: state change from Full to Init 
10:07:31 route,ospf,info OSPFv2 neighbor 10.0.0.2: state change from Full to Down 
10:13:52 route,ospf,info OSPFv2 neighbor 10.0.0.2: state change from Full to Down 
10:15:22 route,ospf,info OSPFv2 neighbor 10.0.0.2: state change from Full to Down 
I tried to use only one instance and backbone area, but very same story happened there too. Clocks are in sync by same NTP servers.

Using 4.11 and 4.17 RouterOS, same story on both versions.
