Hello i would like to ask for some assistance with ospf route preference.
Lets say i have Router A that connect to two upstream routers(B/C). Both Routers B / C run their own ospf area. I wanna make router A to prefer upstream router B as long as its reachable. So far i have tryed to play with cost values, but its random as to what path will be taken, sometimes after cost changes it chooses one path, othertimes other path. I tryed both ways, b with higher cost and lower.
If it helps the client router is Mikrotik and Upstream routers are junipers.
