Part 5.1: Build the Network and Configure Basic Device Settings

In Part 1, you will set up the network topology and configure basic settings and interface addressing on the routers and Layer 3 switches.

Step 1: Cable the network as shown in the topology.

Attach the devices as shown in the topology diagram, and cable as necessary.

Step 2: Configure basic settings for the routers and switches.

a. Console into each router and Layer 3 switch, enter global configuration mode, and apply the basic settings and interface addressing using the following startup configurations for each device.

Open configuration window

Router R1

hostname R1

no ip domain lookup

line con 0

logging sync

exec-time 0 0

exit

banner motd # This is R1, Implement Multi-Area OSPFv2 Lab #

no shut

exit

interface GigabitEthernet0/1

no shut

exit

Router R2

hostname R2

no ip domain lookup

exit

b. Save the running configuration to startup-config.

c. Verify the interface status using the show ip interface brief command.

R1# show ip interface brief | include manual

GigabitEthernet0/0/0 172.16.0.2 YES manual up up

GigabitEthernet0/0/1 10.10.0.1 YES manual up up

R2# show ip interface brief | include manual

GigabitEthernet0/0/0 172.16.0.1 YES manual up up

GigabitEthernet0/0/1 172.16.1.1 YES manual up up

Loopback0 209.165.200.225 YES manual up up

R3# show ip interface brief | include manual

GigabitEthernet0/0/0 172.16.1.2 YES manual up up

GigabitEthernet0/0/1 10.10.4.1 YES manual up up

D1# show ip interface brief | include manual

GigabitEthernet1/0/11 10.10.0.2 YES manual up up

GigabitEthernet1/0/23 10.10.1.1 YES manual up up

D2# show ip interface brief | include manual

GigabitEthernet1/0/11 10.10.4.2 YES manual up up

GigabitEthernet1/0/23 10.10.5.1 YES manual up up

d. Verify direct connectivity between all five devices. R1 is shown as an example.

R1# ping 10.10.0.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.10.0.2, timeout is 2 seconds:

..!!!

Success rate is 60 percent (3/5), round-trip min/avg/max = 2/2/2 ms

R1# ping 172.16.0.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 172.16.0.1, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/1 ms

All five devices should be able to reach the other directly connected networks. Troubleshoot if necessary.
