Lab 6.2.1 Configuring and Verifying Single Area OSPF

Step 1: Connect the equipment

1. Connect Router 1 Serial 0/0/0 interface to Router 2 Serial 0/0/0 interface using a serial cable.
2. Connect Router 1 Fa0/0 interface to Switch 1 Fa0/1 port using a straight-through cable.
3. Connect each PC with a console cable to perform configurations on the router and switches.
4. Connect Host 1 to the Switch 1 Fa0/2 port using a straight-through cable.
5. Connect a crossover cable between Host 2 and the Fa0/0 interface of Router 2.

Step 2: Perform basic configuration on Router 1

1. Connect a PC to the console port of the router to perform configurations using a terminal emulation program.
2. Configure Router 1 with a hostname, interfaces, console, Telnet, IP addresses, and privileged passwords according to the table and topology diagram. Save the configuration.

Step 3: Perform basic configuration on Router 2

Perform basic configuration on Router 1 as the gateway router with a hostname, interfaces, console, Telnet, and privileged passwords according to the table and topology diagram. Save the configuration.

Step 4: Perform basic configuration on Switch 1

Configure Switch 1 with a hostname, console, Telnet, and privileged passwords according to the table and topology diagram.

Step 5: Configure the hosts with the proper IP address, subnet mask, and default gateway

a. Configure each host with the proper IP address, subnet mask, and default gateway.

1) Host 1 should be assigned 192.168.1.130/26 and the default gateway of 192.168.1.129.

2) Host 2 should be assigned 192.168.0.2/24 and the default gateway of 192.168.0.1.

b. Each workstation should be able to ping the attached router. If the ping was not successful, troubleshoot as necessary. Check and verify that the workstation has been assigned a specific IP

address and default gateway.

Step 6: Verify that the network is functioning

1. From the attached hosts, ping the FastEthernet interface of the default gateway router.

Was the ping from the first host successful? yes

Was the ping from the second host successful? yes

If the answer is no for either question, troubleshoot the router and host configurations to find the error.

Ping again until they are both successful.

b.    Use the command show ip interface brief and check the status of each interface. What is the state of the interfaces on each router?

R1:

FastEthernet 0/0: _____ up

Serial 0/0/0: _____ up

Serial 0/0/1: _____administratively down

R2:

FastEthernet 0/0: ______up

Serial 0/0/0: _______p

Serial 0/0/1: ______administratively down

c.     Ping from one of the router connected serial interfaces to the other connected serial interface. Was the ping successful? Jawaban: Ya

Step 7: Configure OSPF routing on R1

1. Configure an OSPF routing process on router R1. Use OSPF process number 1 and ensure that all networks are in Area 0.

Step 8: Configure OSPF routing on R2

1. Configure an OSPF routing process on router R2. Use OSPF process number 1 and ensure that all networks are in Area 0.
2. Examine the R2 running configuration. Did the IOS automatically add any lines under the router ospf 1 command?Jawaban: yes

Step 8: Test network connectivity

Ping Host 2 from Host 1.

Was it successful?Jawaban:  yes

If the answer is no, troubleshoot to find the error. Ping again until successful.

Step 9: Reflection

1. What is an advantage of using OSPF as the routing protocol in a network? Jawaban : that OSPF is efficient, provides fast convergence, and scales well in large networks.

What is a disadvantage of using OSPF as the routing protocol in a network? Jawaban : that OSPF is more difficult to configure and requires proper planning.
