Configuring OSPF OSPF Application Example

Step 2: Enable OSPF

The next step is to load and enable OSPF on each router. The commands for this step are below (the commands are the same on each router):

-> ip load ospf

-> ip ospf status enable

Step 3: Create and Enable the Areas and Backbone

Now the areas should be created and enabled. In this case, we will create an area for each router, and a backbone (area 0.0.0.0) that connects the areas.

The commands for this step are below:

Router 1

-> ip ospf area 0.0.0.0

-> ip ospf area 0.0.0.0 status enable

-> ip ospf area 0.0.0.1

-> ip ospf area 0.0.0.1 status enable

These commands created area 0.0.0.0 (the backbone) and area 0.0.0.1 (the area for Router 1). Both of these areas are also enabled.

Router 2

-> ip ospf area 0.0.0.0

-> ip ospf area 0.0.0.0 status enable

-> ip ospf area 0.0.0.2

-> ip ospf area 0.0.0.2 status enable

These commands created Area 0.0.0.0 (the backbone) and Area 0.0.0.2 (the area for Router 2). Both of these areas are also enabled.

Router 3

-> ip ospf area 0.0.0.0

-> ip ospf area 0.0.0.0 status enable

-> ip ospf area 0.0.0.3

-> ip ospf area 0.0.0.3 status enable

These commands created Area 0.0.0.0 (the backbone) and Area 0.0.0.3 (the area for Router 3). Both of these areas are also enabled.

Step 4: Create, Enable, and Assign Interfaces

Next, OSPF interfaces must be created, enabled, and assigned to the areas. The OSPF interfaces should have the same IP address as the IP router ports created above in “Step 1: Prepare the Routers” on page 1-33.

Router 1

-> ip ospf interface 31.0.0.1

-> ip ospf interface 31.0.0.1 area 0.0.0.0 -> ip ospf interface 31.0.0.1 status enable
