“OSPF always prefers intra-area routes over the inter-area routes, this may cause suboptimal routing…” That is my problem.
RFC 5185 OSPF Multi-Area Adjacency is able to solve this issue. Does RouterOS support RFC 5185? How implement it?
I have used this on Cisco equipment but from what I recall attempting to place an interface in multiple areas within the same OSPF instance gives an error on RouterOS which gave me the impression that it was not implemented.
