How to Configure OSPF on Cisco Router step by step

Router0

Step-1

Router>ena
Router#config t
Router(config)#hostname R1
R1(config)#
R1(config)#int fa0/0
R1(config-if)#ip address 10.0.0.10 255.0.0.0
R1(config-if)#no shut
R1(config)#int se 2/0
R1(config-if)#ip address 20.0.0.1 255.0.0.0
R1(config-if)#clock rate 64000
R1(config-if)#no shut
R1(config-if)#do sho ip route
R1(config-if)#exit

Step-2

R1(config)#router ospf ?
<1-65535> Process ID
R1(config)#router ospf 1 (Process ID)
R1(config-router)#network ?
A.B.C.D Network number
R1(config-router)#network 
R1(config-router)#network 20.0.0.0 ?
A.B.C.D OSPF wild card bits
R1(config-router)#network 20.0.0.0 255.0.0.0 ?
area Set the OSPF area ID
R1(config-router)#network 20.0.0.0 255.0.0.0 area 0
R1(config-router)#network 10.0.0.0 255.0.0.0 area 1
R1(config-router)#exit
R1(config)#

Router1

Step-1

Router>ena 
Router#config t
Router(config)#hostname R2
R2(config)#int fa 0/0
R2(config-if)#ip address 30.0.0.10 255.0.0.0
R2(config-if)#no shut
R2(config-if)#int se 2/0
R2(config-if)#ip address 20.0.0.2 255.0.0.0
R2(config-if)#no shut

Step-2

R2(config)#router ospf 1
R2(config-router)#network 20.0.0.0 255.0.0.0 area 0
R2(config-router)#network 30.0.0.0 255.0.0.0 area 2
R2(config-router)#exit
