Learning Objectives:

  • Design and document an addressing scheme.
  • Apply a basic configuration to the devices.
  • Configure a Routers Priority and RIDs.
  • Configure OSPF routing.
  • Disable routing updates on appropriate interfaces.
  • Verify full connectivity between all devices in the topology.

Task 1: Design and Document an Addressing Scheme.

Use the to create an efficient addressing scheme that meets the following requirements: (Start with the largest network and move to the smallest. Address the WAN link from R5 to R2 first, then the link between R4 to R6.)

Hostname Interface Number of Hosts
R2 Fa0/1 1000
R3 Fa0/1 400
R4 Fa0/1 120
R5 Fa0/1 6000
R5 Fa0/0 800
R6 Fa0/1 2000
R6 Fa0/0 500

Subnets will also need to be assigned for the two serial links in the topology.

NOTE: Interface Fa0/0 has been preconfigured on R1,R2,R3, and R4.

Task 2: Apply a Basic Configuration.

On each router use the following chart to complete the basic router configurations. Also, be sure to configure addressing and hostnames. (R5 gets the first IP in its link with R2 (DCE). R4 (DCE) gets the first IP in its link with R6.)

Task 3: Configure Single-Area OSPF Routing.

Step 1: Configure OSPF (process ID 1) routing on each Router.

Step 2: Verify that all routes were learned.

Task 4: Fine-tuning OSPF.

Step 1: Use the following guidelines to set the OSPF priority:

  • R1 will never participate in a DR/BDR election.
  • R2 will always become the DR.
  • R3 and R4 will both have the same priority of 100.
  • R4 Should always become the BDR.


Step 2: Use Shutdown/No Shutdown on interfaces to force a BR/DR election.

Task 5: Configure a Loopback Interface.

Step 1: On R1 configure the loopback 0 interface with a address.

Step 2: Create a default route to the loopback interface using the local interface argument.

Step 3: Propagate the route within OSPF updates.

Task 6: View OSPF Updates.

Step 1: Enter Simulation mode.

Step 2: Select only OSPF in the filter.

Step 3: View the updates.
