In this lab we will learn to configure multi area ospf using cisco packet tracer.
In below Network Topology Diagram you can see there are Two area Area 0 and Area 1.

Now you have to configure OSPF such that devices in area 0 can easily communicate with devices in Area 1

 

multi area ospf lab

STEP 1:First assign ip address on each interfaces as show in above Diagram.

STEP 2:Now configure OSPF on Router R1:
Router(config)#host R1


R1(config)#router ospf 1


R1(config-router)#network 1.0.0.0 0.255.255.255 area 0


R1(config-router)#network 2.0.0.0 0.255.255.255 area 0


R1(config-router)#router-id 1.1.1.1

 

STEP 3:Configure OSPF on Router R2:
Router(config)#host R2
 
R2(config-router)#network 2.0.0.0 0.255.255.255 area 0
 
R2(config-router)#network 3.0.0.0 0.255.255.255 area 1 
R2(config-router)#router-id 2.2.2.2

 

STEP 4:Now finally Configure OSPF on Router R3:
Router(config)#host R3

R3(config)#router ospf 1


R3(config-router)#network 3.0.0.0 0.255.255.255 area 1



R3(config-router)#network 4.0.0.0 0.255.255.255 area 1


R3(config-router)#router-id 3.3.3.3

 

STEP 5: Now verify your ospf Configuration:

For verification go on middle router named R2:

Verify Route First:

 

R2#show ip route



 

Step 6:Now Verify Protocols running on the ROUTER r2:
R2#show ip protocols


Routing Protocol is "ospf 1"

IF YOU carefully watch the output you will find Two AREA Area 0 and Area 1 active on this Router.

 

STEP 7:Display ospf routing basic information

here you will also see the information about AREA in Details.

 

 

R2#show ip ospf


Routing Process "ospf 1" with ID 3.0.0.1
STEP 8: See OSPF Neighbors.
R2#show ip ospf neighbor

 

SEE Little More details suing below command.

 

R2#show ip ospf neighbor detail
