Thanks mrzIf you are running v5 and have simple queues this error may appear. It is fixed in v6.
My topology is basically star and has grown to a tree-like structure.+1I see the same problem for a month now and didn't see it before 5.18. No topology has changed.
I can see this error on 5.24.
My topology prevent routing loops at all.
I can confirm this. Also got confirmation from Mikrotik support. It's a bug and it will be fixed in future version, but they did not say if it's going to be fixed in RoS 5.On another topic, I don't remember where, I read that this problem could be related to designated router decisions...
I've changed priority on routers with this error some days ago and errors disappeared...
RouterOS 5.x (some 5.22, 5.24 and 5.25)
Is this an error?? To a have two routers connected with two differents interface for backup??Then you have a routing loop, or you have multiple interfaces connected to the same routers and on all of them OSPF is set up.
