OSFP Configuration With single Area 

Configuration of interface

R1(config)# int f0/0
R1(config-if)# ip address 192.168.1.1 255.255.255.0
R1(config-if# no shutdown

R2(config)# int f0/0
R2(config-if)# ip address 192.168.1.2 255.255.255.0
R2(config-if# no shutdown

R2(config)# int s0/0
R2(config-if)# ip address 193.168.1.1 255.255.255.0
R2(config-if# no shutdown



R3(config)# int s0/0
R3(config-if)# ip address 193.168.1.2 255.255.255.0
R3(config-if# no shutdown

Configuration of Routing Protocol OSPF

R1(config)# router ospf 1
R1(config-router)#network 192.168.1.0 0.0.0.255 area 0

R2(config)# router ospf 2
R2(config-router)#network 192.168.1.0 0.0.0.255 area 0
R2(config-router)#network 193.168.1.0 0.0.0.255 area 0

R3(config)# router ospf 1
R3(config-router)#network 193.168.1.0 0.0.0.255 area 0

Now check OSPF protocol working

Troubleshooting command

R1#show ip interface brief

  R1#show ip protocols

R2#show ip protocols

R2#show ip ospf  neighbor

R3#show ip Ospf neighbor
