OSPF protocol is already configured on the routers as pic:

I need solve the problem, but by using Write the instructions in CLI :

Configure loopback interface 0 on each router. Assign the IP address 192.168.0.x/32, where 'x' is the router number (for example 192.168.0.3/32 on R3.) 2. Is there connectivity to the loopback interfaces from the PCs? Why or why not? 3. If there is not, show how your are going to solve the problem 4. Verify the loopback interfaces are in the routing table on R3 5. Verify connectivity from PC1 to the loopback interface on R4 6. Configure the loopback interface and link to R4 as a passive-interfaces on R3. 7. Verify you configuration in part (6)
