I asked this question:
How to filter unused routes in MikroTik routers?

But this question marked as off-topic I wonder how a question about routing and configuring routers at an enterprise-level is off-topic here?

servers operating as a router/switch/firewall;
design or theory of protocols used to operate a network (e.g. IP, TCP, routing protocols, STP, etc);

    I read your question... I think you'll be perfectly happy to assign at least two routers as OSPF ASBRs and announce two default routes as OSPF External Type-1 (Cisco calls them E1) routes. Of course the routers you assign to originate the defaults must be able to get to any IP prefix you require. Jun 10, 2022 at 18:10

That question was first closed because it is too broad, lacking enough detail to be able to answer. It needs a good network description or diagram, the network device models, the network device configurations, any logs, debugs, etc. You can refer to the Network Engineering Question Checklist for guidance on what should be included.

The reason for closure was changed when you admitted that the routers are MikroTik. On the What topics can I ask about here? page, it has a couple of caveats, including:

hardware that has a paid support option from the manufacturer (enterprise/provider class products, some small business class devices);

Unfortunately, MikroTik does not offer that, so its devices are off-topic for NE. This Meta answer goes into more detail about that:

The key difference is that vendors who provide paid support for their own product have a vested interest in the product.


Further, devices with paid support options often also provide better documentation.

  • thanks for your answer. I was searching for a feature in OSPF and I did not care about the specific vendor. can you tell me where should I ask such a broad question? Jul 13, 2021 at 13:13
  • Unfortunately, SE does not allow recommendations for off-site resources, which is understandable because SE does not want to promote its competition. I would need to search for such a site, just as you need to search for it, but I really have no incentive to spend my time on that. You could start with your manufacturer's site, where it may have a place to ask such questions.

  • I find my answer now. but I was asking about OSPF which is a routing protocol and I was asking about a feature in this protocol so I do not think this is too broad. when I read the on-topic section I supposed that this question is on-topic because of the part that I quoted here.
