I had my OSPF working fine, when it was just 1 mikrotik and 2 cisco routers. But since I switched to 2 mikrotiks and 1 cisco, I am still not getting it to work (from thread http://forum.mikrotik.com/viewtopic.php?t=10281 ).
I'm hoping my problem just has to do with configuration. But both my routers are using 2.9.28.
I have not tried it with 2.9.28 yet but I do have quite a few OSPF connections working with 2.9.27. If you could post what you have, it would be easier to troubleshoot for me then just posting what we have. Either that or message me personally and we can email back and forth.
