l4-Part 1: Configure Basic Device Settings and Interface Addressing

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

Note: The Layer 2 switch should only have a default configuration.

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 router and the two Layer 3 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

interface Loopback0

ip address 209.165.200.225 255.255.255.224

no shut

exit

interface Loopback1

ip address 192.168.1.1 255.255.255.192

no shut

exit

interface GigabitEthernet0/0

ip address 10.10.0.1 255.255.255.248

no shut

exit

Switch D1

hostname D1

no ip domain lookup

line con 0

logging sync

exec-time 0 0

exit

interface g0/1

no switchport

ip address 10.10.0.2 255.255.255.248

no shut

exit

interface g0/0

no switchport

ip address 10.10.8.1 255.255.255.0

no shut

exit

interface g0/2

no switchport

ip address 10.10.9.1 255.255.255.0

no shut

exit

Switch D2

hostname D2

no ip domain lookup

line con 0

logging sync

exec-time 0 0

exit

interface g0/2

no switchport

ip address 10.10.0.3 255.255.255.248

no shut

exit

interface g0/0

no switchport

ip address 10.10.24.1 255.255.255.0

no shut

exit

interface g0/1

no switchport

ip address 10.10.25.1 255.255.255.0

no shut

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 10.10.0.1 YES manual up up

Loopback0 209.165.200.225 YES manual up up

Loopback1 192.168.1.1 YES manual up up

D1# show ip interface brief | include manual

GigabitEthernet0/0 10.10.8.1 YES manual up up

GigabitEthernet0/1 10.10.0.2 YES manual up up

GigabitEthernet0/2 10.10.9.1 YES manual up up

D2# show ip interface brief | include manual

GigabitEthernet0/0 10.10.24.1 YES manual up up

GigabitEthernet0/1 10.10.25.1 YES manual up up

GigabitEthernet0/2 10.10.0.3 YES manual up up

d. Verify direct connectivity between the highlighted IP addresses of R1, D1, and D2.

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 = 2/2/3 ms

R1# ping 10.10.0.3

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.10.0.3, timeout is 2 seconds:

..!!!

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

All three devices should be able to reach the other directly connected networks (i.e., 10.10.0.0/29). Troubleshoot if necessary.
