I’m not sure this functionality works. There was another user who posted a few months back with the same issue. http://forum.mikrotik.com/t/ospf-vrf-connected-static-route-redistribution/39793/1
I can confirm redistribute-static and redistribute-connected work when using BGP as the routing protocol; /routing bgp instance vrf. I’ll setup a test environment to try and redistribute connected routes via OSPF, but for now this is the only input I can offer.
