2. On R1 enable OSPF routing with process 1 and area as 200 for the network 192.168.1.0
3. On R2 enable OSPF routing with process 1 and area as 200 for the network 192.168.1.0,192.168.1.4,192.168.1.8
4. On R3 enable OSPF routing with process 1 and area as 200 for the network 192.168.1.0
5. On R4 enable OSPF routing with process 1 and area as 200 for the network 192.168.1.8
6. Ping R3 from R2, you will see ping failure
7. Ping R2 from R1 and R4, you will see ping success 
8. Issue show running-config command on R3 to check the output.
