We are have a link between 2 locations on our network that seem to have their OSPF Neighbor Status intermittently bounce from Exchange to 2-Way. Here is a basic layout.
Switch------MikrotikEndRouter----MicrowaveBridge1----------------------------------------MicrowaveBridge2----MikrotikCoreRouter-----CORE-NETWORK
Most of the time everything works fine, however intermittently my OSPF neighbor relationship between the MikrotikEndRouter and MikrotikCoreRouter will start bouncing between Exchange and 2-Way States and the MikrotikEndRouter will be inaccessible except from the local network it belongs to. I.E. I can telnet from MikrotikCoreRouter to MikrotikEndRouter but can't get to it from anywhere else on my network.
The temporary fix is to reboot the MicrowaveBridge1 and my OSPF Neighbor relationships will start working again from anywhere from a few hours to a few weeks.
I also noticed in my MikrotikCoreRouter logs the error message "Ignoring Link State Acknowledgment packet: wrong peer state=2-Way"
Any thoughts as to what might be causing this issue and what the fix might be? My Microwave Link appears rock solid and I never have problems accessing either of the Microwave radios.
What do you think?
