Hi Abdurahman,

The longest matched is determined based on the destination address which you are tying to reach.

According the snap shot the destination you are tryhting to reach is 192.168.3.23.

You have two routes here in the routinng table i.e.

192.168.0.0/22

192.168.1.0/24

The ip's included in the subnet 192.168.1.0/24 is from 192.168.1.0 to 255 and this does not include 192.168.3.23. Since 192.168.3.23 is not in the subnet range of 192.168.1.0/24 router will match the next avialable network which is 192.168.0.0 (i.e route 1 as per your snapshot)

So the solution in the snap shot is correct.
