🖧 CCNA Network Lab: SOHO Branch – XYZ Company

Design and Implementation of a Small Office Home Office Network – Project #2

📝 Project Description

Design a network in Cisco Packet Tracer for XYZ Company’s new branch in Bonalbo, Eastern Australia, with the following requirements:

• Single-branch network operating separately from HQ.
• Three departments: Admin/IT, Finance/HR, and Customer Service/Reception.
• Each department should have its own VLAN and wireless network.
• All PCs and wireless devices obtain IP addresses via DHCP.
• Printers are assigned static IP addresses outside DHCP pools.
• Devices in all departments should communicate via inter-VLAN routing.
• Base network: 192.168.1.0/24.

🗺️ Topology

• 3 departments: Admin/IT, Finance/HR, Customer Service/Reception
• Each department has PCs connected to a switch
• Wireless Access Points for each department
• Main-Router connects all VLANs via router-on-a-stick

🛠️ Technologies Implemented

• Router-on-a-stick for inter-VLAN routing
• Creating VLANs and assigning switch ports
• Configuring DHCP pools and excluded addresses for static devices
• Configuring wireless access points for each department
• Static IP assignment for printers
• Port-security with sticky MACs
• BPDU Guard and PortFast on access ports
• Subnetting and IP Addressing
• Testing and Verifying Network Communication

✅ Test Results

• All PCs in Admin/IT can ping each other ✅
• All PCs in Finance/HR can ping each other ✅
• All PCs in Customer Service/Reception can ping each other ✅
• Inter-VLAN communication between all departments via Main-Router ✅
• Printers are reachable from all departments ✅
• Wireless clients successfully obtain DHCP addresses ✅

🧪 Testing & Verification

Verify VLAN assignments on the switch:

Main-Switch#show vlan brief

VLAN	Name	Status	Ports
1	default	active
10	Admin_IT	active	Fa0/1, Fa0/2, Fa0/3
20	Finance_HR	active	Fa0/4, Fa0/5, Fa0/6
30	Customer-Service_Reception	active	Fa0/7, Fa0/8, Fa0/9
998	Native	active
999	Parking_Lot	active	Fa0/10, Fa0/11, Fa0/12, Fa0/13, Fa0/14, Fa0/15, Fa0/16, Fa0/17,
			Fa0/18, Fa0/19, Fa0/20, Fa0/21, Fa0/22, Fa0/23, Fa0/24, Gig0/2
1002	fddi-default	active
1003	token-ring-default	active
1004	fddinet-default	active
1005	trnet-default	active

Verify DHCP bindings on the router:

Main-Router#show ip dhcp binding

IP Address	Client-ID / Hardware Address	Lease Expiration	Type
192.168.1.71	000B.BED2.BE00	--	Automatic
192.168.1.72	000A.F3D6.45C3	--	Automatic
192.168.1.134	0002.161D.AAD6	--	Automatic
192.168.1.135	0003.E411.D8A3	--	Automatic
192.168.1.198	0000.0C76.9844	--	Automatic
192.168.1.199	0001.9619.3A87	--	Automatic

Test inter-VLAN connectivity: ping

Verify connectivity to static devices (printers):

Confirm routing between VLANs on the router:

Main-Router>show ip route

Code	Network	Mask	Next Hop / Interface
-	192.168.1.0/24	variably subnetted, 6 subnets, 2 masks	-
C	192.168.1.64/26	255.255.255.192	directly connected, G0/0/1.10
