Part 1: Configure Basic Device Settings
In Part 1, you will set up the network topology and configure basic router settings, such as the interface IP
addresses, routing, device access, and passwords.
Step 1: Cable the network as shown in the topology.
Attach the devices as shown in the Topology, and cable as necessary.
Step 2: Initialize and reload the routers and switches.
Step 3: Configure basic settings for each router.
a. Disable DNS lookup.
b. Configure the device name.
c. Encrypt plain text passwords.
d. Create a message of the day (MOTD) banner warning users that unauthorized access is prohibited.
e. Assign class as the encrypted privileged EXEC mode password.
f. Assign cisco as the console and vty password and enable login.
g. Set console logging to synchronous mode.
h. Apply the IP addresses to Serial and Gigabit Ethernet interfaces according to the Addressing Table and
activate the physical interfaces.
i. Set the clock rate to 128000 for DCE serial interfaces.
j. Create Loopback0 on the Central router to simulate access to the Internet and assign an IP address
according to the Addressing Table.
Step 4: Configure routing.
a. Enable single-area OSPF on the routers and use a process ID of 1. Add all the networks, except
209.165.200.224/27 into the OSPF process.
b. Configure a default route to the simulated Internet on the Central router using Lo0 as the exit interface
and redistribute this route into the OSPF process.
c. Issue the show ip route ospf, show ip ospf interface brief, and show ip ospf neighbor commands on
all routers to verify that OSPF is configured correctly. Take note of the router ID for each router.
Branch1:
Branch1# show ip route ospf
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override
Gateway of last resort is 10.1.1.2 to network 0.0.0.0
