I'm having some trouble with OSPF routing.
I have quite simple network see URL: http://jirka.ehm.cz/temp/ospfnetwork.pdf
Router's A, B, C are in area 0.0.0.0 and router A is connected to internet.
Problem is with this topology router B somehow think's that better way for network's in area2 and area 3 is all the way throught area1 router's ( B > R1 > R2> R3 > C ) instead of using simple fast ethernet and go B > C.
I also draw to image OSPF cost's to links between mikrotik's.
So is this a feature or bug or I have something misconfigured?
thank you for any help!
