Lab Simulation 35
Guidelines
This is a lab item in which tasks will be performed on virtual devices.
- Refer to the Tasks tab to view the tasks for this lab item.
- Refer to the Topology lab to access the device console(s) and perform the tasks.
- Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.
- All necessary preconfigurations have been applied.
- Do not change the enable password or hostname for any device.
- Save your configurations to NVRAM before moving to the next item.
- Click Next at the bottom of the screen to submit this lab and move to the next question.
- When Next is clicked, the lab closes and cannot be reopened.
Topology

Tasks
Refer to the topology. All physical cabling is in place. Routers 2 and 3 are inaccessible. Configure OSPF routing for the network and ensure R1 has joined Area 0 without using network statements.
Task 1
- Configure OSPF on R1 with a process ID and router- ID only as follows:
o use process ID 33
o use EO/1 IP as the router ID
Task 2
- Configure R1 to establish neighbor adjacencies with R2 and R3. The network statement under the OSPF process must not be used.
- Configure R1 to always become the DR for Area 0
Correct Answer:
R1# configure terminal
R1(config)# interface e0/1
R1(config-if)# ip address 10.0.22.1 255.255.255.252
R1(config-if)# exit
R1(config)# interface e0/2
R1(config-if)# ip address 10.0.33.1 255.255.255.252
R1(config-if)# exit
R1(config)# interface e0/0
R1(config-if)# ip address 10.0.233.1 255.255.255.240
R1(config-if)# exit
R1(config)# router ospf 33
R1(config-router)# router-id 10.0.22.1
R1(config-router)# interface e0/0
R1(config-if)# ip ospf 33 area 0
R1(config-if)# ip ospf priority 255
R1(config-if)# exit
R1(config-router)# interface e0/1
R1(config-if)# ip ospf 33 area 0
R1(config-if)# ip ospf priority 255
R1(config-if)# exit
R1(config-router)# interface e0/2
R1(config-if)# ip ospf 33 area 0
R1(config-if)# ip ospf priority 255
R1(config-if)# exit
