OSPF Single Area configuration on Packet Tracer Lab with PDF

OSPF Single Area configuration on Packet Tracer:

This OSPF lab is created in packet tracer and you will learn the OSPF single area configuration from this lab. OSPF is an open standard protocol, you learn more why we use OSPF and OSPF Quiz from here.

Configuring the OSPF Routing Process

This is a basic labs regarding OSPF single area configure related to CCNA or ICND1/2 exam. In following figure there are the three routers with the following specification or required configurations:

Device Name Protocol configuration IP Scheme / Interface configurations
PC0 F0 = 192.168.44.2\24
PC1 F0 = 10.10.22.2\24
Router0 OSPF 1 G0/0 = 192.168.44.1\24, G0/1 = 192.168.55.1\24
Router1 OSPF 1 G0/0 = 192.168.55.2\24,  G0/1 = 172.16.10.1\24
Router2 OSPF 1 G0/0 = 172.16.10.2\24, G0/1 = 10.10.22.1\24

Lab Objective

• Setup an IP addressing scheme on all the devices according to above table.

• Configure and verify Open Shortest Path First (OSPF) routing.

Solution:

Configure and create the above lab in packet tracer and complete the IP configuration with following configurations:

Router0 IP and interface Configuration:

On the router, enter the global configuration mode and configure the hostname as shown in the chart. Then configure the console, virtual terminal and enable passwords. Next configure the interfaces according to the chart.

Router>enable

Router#conf t

Router(config)#hostname Router0

Router0(config)#interface gigabitEthernet 0/0

Router0(config-if)#ip address 192.168.44.1 255.255.255.0

Router0(config-if)#no shut

Router0(config-if)#exit

Router0(config)#interface gigabitEthernet 0/1

Router0(config-if)#ip address 192.168.55.1 255.255.255.0

Router0(config-if)#no shutdown

 

Router1 IP Configuration:

Perform the same configuration as on above router with their IP scheme.

Router>enable

Router#conf t

Router(config)#hostname Router1

Router1(config)#interface gigabitEthernet 0/0

Router1(config-if)#ip address 192.168.55.2 255.255.255.0

Router1(config-if)#no shut

Router1(config-if)#exi

Router1(config)#interface gigabitEthernet 0/1

Router1(config-if)#ip address 172.16.10.1 255.255.255.0

Router1(config-if)#no shutdown

Router2 IP and interface Configuration:

Router>enable

Router#conf t

Router(config)#hostname Router2

Router2(config)#int gigabitEthernet 0/0

Router2(config-if)#ip address 172.16.10.2 255.255.255.0

Router2(config-if)#no shut

Router2(config-if)#exit

Router2(config)#interface gigabitEthernet 0/1

Router2(config-if)#ip address 10.10.22.1 255.255.255.0

Router2(config-if)#no shutdown

PC0 Configuration:

Assign the IP address, subnet mask and gateway. 255.255.255.0 is the Subnet mask and gateway will be the next hope address of router or the IP of router-interface attached with PC, and in this case it is 192.168.44.1. Each workstation should be able to ping the attached router. For more details you can watch this video:

PC1 Configuration:

Configure this workstation with following IPs:

IP address: 10.10.22.2

Subnet Mask: 255.255.255.0

Gateway: 10.10.22.1

Task2 Configure and verify Open Shortest Path First (OSPF) routing:

Configure an OSPF routing process on all routers. Use OSPF process number 1 and ensure all networks are in area 0. For configuring any router with OSPF you need to advertise all the directly connected network in OSPF process. For example on router0 you have the networks 192.168.44.0/24 and 192.168.55.0/24 so you can see that I have advertise these network in area 0 for OSPF configurations.

Router0 OSPF Configuration:

Router0#conf t

Router0(config)#router ospf 1

Router0(config-router)#network 192.168.44.0 0.0.0.255 area 0

Router0(config-router)#network 192.168.55.0 0.0.0.255 area 0

Router0(config-router)#exit

 

Router1 OSPF Configuration:

Router1#conf t

Router1(config)#router ospf 1

Router1(config-router)#network 192.168.55.2 0.0.0.255 area 0

Router1(config-router)#network 172.16.10.0 0.0.0.255 area 0

Router1(config-router)#exit

Router2 OSPF Configuration:

Router2#conf t

Router2(config)#router ospf 1

Router2(config-router)#network 172.16.10.0 0.0.0.255 area 0

Router2(config-router)#network 10.10.22.0 0.0.0.255 area 0

Router2(config-router)#exit

 

Note: You can use the “ip OSPF area 0” command for configuring OSPF. For this you have enter the interface mode and then run the commands in following way. for router2 you can use these commands:

Router2>en

Router2#conf t

Router2(config)#inter gigabitEthernet 0/0

Router2(config-if)#ip ospf area 0

Router2(config)#inter gigabitEthernet 0/1

Router2(config-if)#ip ospf area 0

But you are required the newer version of IOS for configuring these commands.

Testing for correct configuration:

You can ensure the correct configuration by following two ways:

1.      end to end ping should be successful, this mean ping from PC0 to PC1 and vice versa should be successful. you can see the following image, we will have the same results in case of correct configurations.

end-to-end-ping-ospf

2.      Show ip route command will display all the OSPF routes (including the networks which are not connected to router). Screenshot of “Show ip route” on Router0 will have the following output in case of correct configurations.

show ip route ospf

You can also download the packet tracer file  and PDF files which contain the complete configuration for this lab:
