Routing Protocols and Concepts Exploration Routing: OSPF Skills Based Assessment
Remote_1
Remote_2
Upon completion of this lab, you will be able to:
· Create an addressing scheme to accommodate the hosts on the network
· Cable network according to the diagram
· Configure OSPF
· Configure OSPF priorities
· Configure OSPF cost
· Configure OSPF authentication
· Configure a static default route
You are a network engineer for an ISP with multiple locations that are connected through a switch. You are assigned the task of creating an addressing scheme for each client’s LAN. You must set the OSPF priorities so that the ISP router is the DR and the Remote_1 router is the BDR. You must also make sure that the Remote_2 router never takes part in the DR/BDR election. Authentication must also be set so that a rouge router cannot connect to the network and propagate false routes into the network.
Task 1: Create an Addressing Scheme.
Step 1: Create an addressing scheme for each LAN using the 192.168.1.0/24 address space.
Remote_1:
· Lo0: 60 Hosts
· Lo1: 12 Hosts
Remote_2:
· Lo0: 62 Hosts
· L01: 28 Hosts
Step 2: Record the appropriate subnet address and mask in Table 1.

Task 2: Cable and Configure Network.
Step 1 Cable the network according to the Topology Diagram.
Step 2 Place the correct interface address for each router in Table 2.
Table 2
10.10.10.1
255.255.255.252
188.46.37.254
10.10.10.3
10.10.10.2
Step 3 Verify the configurations.
Task 3: Basic OSPF Configuration.
Step 1 Configure OSPF on each router.
Use Process ID 1 and advertise all directly connected networks in OSPF Area 0. Do not advertise the loopback interface on the ISP router.
Step 2 Verify the OSPF configuration.
Confirm that each router has formed an adjacency with one another and has a path to each network in the topology.
Task 4: Confirm OSPF Priorities.
Step 1: Verify the OSPF priorities.
Confirm that the DR/BDR election took place and that the ISP router is the DR, Remote_1 is the BDR and the Remote_2 router is the DROTHER.
Step 2: Configure the ISP router with the highest possible OSPF priority.
Step 3: Assure that the Remote_2 router will never take place in the DR/BDR election process...
