• VLAN 20 handles the device connections to Router 2, using the IP router port 20.0.0.2 and physical 

ports 2/3-5. More ports could be added at a later time if necessary.

The router was assigned the Router ID of 2.2.2.2.

Router 3 (using ports 2/1 and 2/2 for the backbone, and ports 2/3-5 for end devices):

-> vlan 23

-> ip interface vlan-23 vlan 23 address 23.0.0.3 mask 255.0.0.0

-> vlan 23 port default 2/1

-> vlan 31

-> ip interface vlan-31 vlan 31 address 31.0.0.3 mask 255.0.0.0

-> vlan 31 port default 2/2

-> vlan 30

-> ip interface vlan-30 vlan 30 address 30.0.0.3 mask 255.0.0.0

-> vlan 30 port default 2/3-5

-> ip router router-id 3.3.3.3

These commands created VLANs 23, 31, and 30. 

• VLAN 23 handles the backbone connection from Router 2 to Router 3, using the IP router port 

23.0.0.3 and physical port 2/1.

• VLAN 31 handles the backbone connection from Router 3 to Router 1, using the IP router port 

31.0.0.3 and physical port 2/2.

• VLAN 30 handles the device connections to Router 3, using the IP router port 30.0.0.3 and physical 

ports 2/3-5. More ports could be added at a later time if necessary.

The router was assigned the Router ID of 3.3.3.3.

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

Now the area should be created. In this case, we will create area 0.0.0.1. The command for this step is 
below (the command is the same on each router): 

-> ip ospf area 0.0.0.1

Area 0.0.0.1 is created and enabled.

Next, OSPF interfaces must be created, enabled, and assigned to area 0.0.0.1. The OSPF interfaces should 
have the same interface name as the IP router interfaces created above in 

.
