Assuming that there is another requirement for the above figure:
Device A shall give preference to device B to reach the destination network of
192.168.23.0/24. To achieve this goal, the cost of neighbor shall be specified
while configuring this neighbor.
Execute the following commands on device A:
router ospf 1
neighbor 192.168.123.2 cost 100
neighbor 192.168.123.3 cost 200

Requirements
Four devices form a OSPF routing domain. Network 192.168.12.0/24 and
192.168.23.0/24 belong to area 0, and network 192.168.34.0/24 belongs to area
34. Details about IP address assignment and device connection are shown in Fig
