CyberPatriot Cisco Labs Guide (Modules 1โ€“7)
This guide shows how to create three essential Packet Tracer labs for the CyberPatriot Cisco round.
Each lab includes the topology diagram, step-by-step setup, and commands to verify success.
Lab 1 โ€“ Basic Device Configuration + Connectivity
Goal: Connect two PCs through two routers and verify end-to-end communication.
Topology Diagram:
PC1 --- Switch1 --- Router1 --- Router2 --- Switch2 --- PC2
Step 1: Assign IP addresses according to the following table.
Device Interface IP Address Subnet Mask
PC1 NIC 192.168.1.10 255.255.255.0
Router1 G0/0 192.168.1.1 255.255.255.0
Router1 G0/1 10.0.0.1 255.255.255.252
Router2 G0/0 10.0.0.2 255.255.255.252
Router2 G0/1 192.168.2.1 255.255.255.0
PC2 NIC 192.168.2.10 255.255.255.0
Step 2: Configure routers.
enable configure terminal hostname Router1 interface g0/0 ip address 192.168.1.1
255.255.255.0 no shutdown interface g0/1 ip address 10.0.0.1 255.255.255.252 no
shutdown ip route 192.168.2.0 255.255.255.0 10.0.0.2
Repeat similar steps for Router2.
Step 3: Test connectivity using ping between PCs.
Lab 2 โ€“ VLANs + Trunking
Goal: Configure VLANs and trunking so only PCs in the same VLAN can communicate.
Topology Diagram:
PC1---S1---S2---PC2 | | | +--PC3
VLAN Setup:
VLAN Name PCs
10 Accounting PC1, PC2
20 Engineering PC3

CyberPatriot Cisco Labs Guide (Modules 1โ€“7)

This guide shows how to create three essential Packet Tracer labs for the CyberPatriot Cisco round.

Each lab includes the topology diagram, step-by-step setup, and commands to verify success.

Lab 1 โ€“ Basic Device Configuration + Connectivity

Goal: Connect two PCs through two routers and verify end-to-end communication.

Topology Diagram:

PC1 --- Switch1 --- Router1 --- Router2 --- Switch2 --- PC

Step 1: Assign IP addresses according to the following table.

Device Interface IP Address Subnet Mask

PC1 NIC 192.168.1.10 255.255.255.

Router1 G0/0 192.168.1.1 255.255.255.

Router1 G0/1 10.0.0.1 255.255.255.

Router2 G0/0 10.0.0.2 255.255.255.

Router2 G0/1 192.168.2.1 255.255.255.

PC2 NIC 192.168.2.10 255.255.255.

Step 2: Configure routers.

enable configure terminal hostname Router1 interface g0/0 ip address 192.168.1. 255.255.255.0 no shutdown interface g0/1 ip address 10.0.0.1 255.255.255.252 no shutdown ip route 192.168.2.0 255.255.255.0 10.0.0.

Repeat similar steps for Router2.

Step 3: Test connectivity using ping between PCs.

Lab 2 โ€“ VLANs + Trunking

Goal: Configure VLANs and trunking so only PCs in the same VLAN can communicate.

Topology Diagram:

PC1---S1---S2---PC2 | | | +--PC

VLAN Setup:

VLAN Name PCs

10 Accounting PC1, PC

20 Engineering PC

Configuration commands:

vlan 10 name Accounting vlan 20 name Engineering interface f0/1 switchport mode access switchport access vlan 10 interface f0/2 switchport mode access switchport access vlan 20 interface f0/24 switchport mode trunk

Verify using 'show vlan brief' and 'show interfaces trunk'.

Lab 3 โ€“ Router-on-a-Stick (Inter-VLAN Routing)

Goal: Allow VLANs to communicate through a router using subinterfaces.

Topology Diagram:

PC1(VLAN10) -- Switch -- Router -- PC2(VLAN20)

Router Configuration:

interface g0/0.10 encapsulation dot1Q 10 ip address 192.168.10.1 255.255.255. interface g0/0.20 encapsulation dot1Q 20 ip address 192.168.20.1 255.255.255. interface g0/0 no shutdown

Switch Configuration:

vlan 10 vlan 20 interface g0/1 switchport mode trunk interface f0/2 switchport mode access switchport access vlan 10 interface f0/3 switchport mode access switchport access vlan 20

Verify connectivity using ping between PCs in VLAN10 and VLAN20.
