Exploration Routing: OSPF Skills Based Assessment (Instructor
Version)
Exam Objectives
Completion of this exam requires the following tasks:

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

Verify OSPF operation

Configure a static default route
Scenario
You are a network engineer for a company 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 HQ 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.

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

Task 3: Basic OSPF Configuration.
Step 1 Configure OSPF on each router.
Use Process ID 1and advertise all directly connected networks in OSPF Area 0. Advertise the loopback
interface on the HQ router.
Remote_1:
Remote_1(config)#router ospf 1
Remote_1(config-router)#network 10.10.10.0 0.0.0.7 area 0
Remote_1(config-router)#network 192.168.1.0 0.0.0.63 area 0
Remote_1(config-router)#network 192.168.1.160 0.0.0.15 area 0
Remote_2:
Remote_2(config)#router ospf 1
Remote_2(config-router)#network 10.10.10.0 0.0.0.7 area 0
Remote_2(config-router)#network 192.168.1.64 0.0.0.63 area 0
Remote_2(config-router)#network 192.168.1.128 0.0.0.31 area 0
HQ:
HQ(config)#router ospf 1
HQ(config-router)#network 10.10.10.0 0.0.0.7 area 0
HQ(config-router)#network 188.46.37.252 0.0.0.3 area 0
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 Remote_1 router is the DR, Remote_2 is the
BDR and the HQ router is the DROTHER.

Step 2: Configure the HQ router with the highest possible OSPF priority.
HQ(config)#int fa0/0
HQ(config-if)#ip ospf priority 255
Step 3: Assure that the Remote_2 router will never take place in the DR/BDR election process.
Remote_2(config)#int fa0/0
Remote_2(config-if)#ip ospf priority 0
Step 4: Reboot the switch using the reload command to force the OSPF election process.
Step 5: Verify that the OSPF election has occurred.
Confirm that the HQ router is now the DR, the Remote_1 router is the BDR and the Remote_2 router is now
the DROTHER.

Task 7: Static Default Route
Step 1: Configure a static default route on the HQ router.
HQ(config)#ip route 0.0.0.0 0.0.0.0 lo0
Step 2: Propagate the static default route to the other routers in the network.
HQ(config)#router ospf 1
HQ(config-router)#default-information originate
Step 3: Verify that each router can see the static default route in their routing table.

Instructor’s Initial ______
Task 8: Verify Connectivity
Step 1 Ping the loopback interface on the HQ router from the Remote_1 and Remote_2 routers.
Remote_1:
Remote_1#ping 188.46.37.254
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 188.46.37.254, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
Remote_2:
Remote_2#ping 188.46.37.254
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 188.46.37.254, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
