Hello Fazail
When you have a non-broadcast network type, in order to configure the OSPF neighbors manually, it is necessary to configure the neighbor command on only one of the two OSPF routers. Once this is done, the hub router will send out OSPF hello packets to the spokes to establish an adjacency. The spoke routers will respond to this and will create the neighbor adjacency.
Just to be sure, I’ve labbed this up myself as well, and after a few seconds, the adjacency does come up. You can see that this is also the case for EIGRP, as stated in this post:
I hope this has been helpful!
