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?

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.
