OSPF adjancy keeps droping

Hi Guys,
I have a remote router RB1200 talking to the rest of my network via OSPF. It seems that only lately it is loosing connectivity via OSPF to the rest of the network. When I get alerts that its gone down, none of my routers on the network can ping it, only the router it is directly connected to. I have to telnet from the neighbouring router into the RB1200 to do a system reboot. After a minute when the 1200 comes up, all is working again.

The only strange thing that I notice was that on the neighbouring router under ospf/neighbours, it is showing me up to 1000 state changes for the RB1200.

Is there anyway I could track down what is going wrong in the RB1200 from the command line to view the logs or something?

It done it again…but this time I got a snap view of the logs…what do they mean?

Had the same problem awhile ago.
Solved it by replacing the ethet cable.

Anyway some thing you can check…

\

  1. Both routers have same routeros.
  2. Time needs to be the same on both routers.
