Hello Good People,
Thanks to all for nice cooperation in advance. According to my below drawing, pleases suggest me best OSPF configuration. In future, MPLS may be implemented on this network.

Thank you.

Is this a commercial setup?

Still in the lab. But this network will be implemented soon. There's no option to change physical connectivity.

I guess Larsa wanted to say: hire a Mikrotik expert for such kind of questions when it is for commercial use. You make money with it, but want knowledge for free.

But nevertheless, maybe still someone can give you pointers.

Correct, that was the intention behind my question.

OSPF comes with various quirks that one must be aware of, thus there is no standard configuration that can be applied in this case.

You either bring in a consultant or learn the hard way by studying and performing hands-on testing in the lab and get back with specific questions.
