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 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
