Hi,
I’ve got same problem as here http://forum.mikrotik.com/t/ospf-neighbors-in-ros-3-14-stuck-in-full-exchange-state/23940/1 but there is still no good answer.
My configuration
[RT1, RB2011L@6.10]-----[RB912U@6.10])))) (((([RB912U@6.10]-----[RT2, RB2011UiAS@6.10]
)))) (((( wireless

area type: stub
adjacency: max 40s
The same situation on nbma and broadcast neighbors.
problem goes away when I reboot one of routers or enable/disable ospf instance, but it’s annoying.
