Now it is required that the RTC must not learn the routes configured in the above RTA, what configurations can be performed on the router?

In the topology shown in the figure, perform the following configurations on RTA and RTB respectively

RTA-ospf-1-area-0.0.0.1] network 192.168.0.0 0.0.0.255

RTA-ospf-1-area-0.0.0.1] network 192.168.1.0 0.0.0.255

RTA-ospf-1-area-0.0.0.1] network 192.168.2.0 0.0.0.255

RTA-ospf-1-area-0.0.0.1] network 192.168.3.0 0.0.0.255

RTA-ospf-1-area-0.0.0.1] network 192.168.4.0 0.0.0.255

Now it is required that the RTC must not learn the routes configured in the above RTA, what configurations can be performed on the router? (Multiple choice)
