New Router cannot maintain OSPF Link: 5 seconds on, 5 seconds off

Tue Jan 03, 2023 10:53 am

Greetings Mikrotik Forum,

I've setup a new CCR1036-12G-4S router at a new office that is opening this month. I've created a GRE tunnel back to the main office router which seems to be stable and working properly. I'm attempting to use OSPF to share routes between the sites. The main office router is router ID 10.1.0.200. The new office is router ID 10.12.0.200. This issue is that on 10.1.0.200 the route back to the new office subnet, 10.12.0.0/16, stays up for 5 seconds, then drops for 5 seconds, comes back for 5 seconds, drops again for 5 seconds, etc. The new office router maintains all its routes full time, the issue appears to be one-way only.

My first thought is that this would be caused by a firewall at the new office. To test, I disabled every firewall rule that drops a packet. The issue was unaffected. This seems to rule out the firewall as the problem.

My next idea was that the issue was related to the GRE tunnel. I disabled the GRE tunnel and setup an LT2P tunnel between the two sites as a test. The L2TP tunnel established fine, but the OSPF issue is exactly the same on this tunnel. It only breaks one-way, and it goes 5 seconds on, 5 seconds off.

To confirm which router has the issue, I created an L2TP tunnel between the new office and a third router at a different site. The OSPF issue still exists on this tunnel, where the third router still drops the route for 5 seconds, then adds it back for 5 seconds. To me, this says the issue must be on the new office router. None of the other dozen routers in our network have ever experienced this issue, but this issue exists whenever I create a tunnel between this new office and another router.

I'm out of ideas why this might be happening, and I request help and the wisdom of the forum. Any help or ideas would be appreciated.

Here is my sanitized router config from the new office:

Re: New Router cannot maintain OSPF Link: 5 seconds on, 5 seconds off

Fri Feb 17, 2023 10:23 pm

Mikrotik Support came through and helped us solve this issue. Apparently we had a duplicate router ID on our network, leftover on another Mikrotik router that previously had the same subnet we reused on our new router. Updating the router IDs to their correct IP addresses has resolved the issue.
