Question

This is my network, and assuming all cost for ospf in the links are 1, there are two path from 1-4 obviously.
I tried in the real network and the result shows that the network tries to get advantage of these two paths together but in my OMNeT++ simulation always one path which is 1-2-4 is prefered, What things is wrong in my files and how can i change it to make it more closer to real network?
