How to set 1 router? / gimana caranya setting 1 router?

I use software cisco packet tracer to analyze.

1. Make the network topology as below

2. double klik on router icon  and klik CLI tab

 Commands CLI tab:

    --- System Configuration Dialog ---

Continue with configuration dialog? [yes/no]: n

Press RETURN to get started!

Router>enable
Router#config t

Router(config)#interface fa 0/0
Router(config-if)#ip address 192.168.1.20 255.255.255.0
Router(config-if)#no shutdown

Router(config-if)#exit
Router(config)#exit
Router#write
Building configuration...
[OK]
Router#exit

- As well as the setting of the second network, change ip network becomes 192.168.0.20 255.255.255.0

Router>enable
Router#config t

Router(config)#interface fa 0/0
