University Network Design Project

Main Building (3 Sub-Buildings), Each connected to a Layer 3 switch

Building A:

Contains 4 departments. Each department has:

Assigned to its own VLAN from VLAN 10 to VLAN 40

Building B:

Has 2 departments, each has:

Assigned VLAN 50 and VLAN 60

Building C:

Has 2 sections:

One section hosts a Web Server and an FTP Server in VLAN 80

The second section uses VLAN 70

Second Building

Contains 2 departments:

Each connected to a Layer 3 switch

Assigned VLAN 90 and VLAN 100

? Key Technologies Used:

VLAN Configuration

Each department/section is segmented using VLANs (from VLAN 10 to 100) for better security, traffic management, and broadcast isolation.

VLANs were defined on the Layer 3 Switch with proper interface configurations.

Trunk & Access Ports

*Access ports were used to connect end devices (PCs and printers) to their designated VLANs.

*Trunk ports were configured to carry multiple VLANs between switches and to the Layer 3 switch.

Layer 3 Switch

Used for Inter-VLAN Routing within each building to enable communication between VLANs while maintaining segmentation.

DHCP Configuration

· Configured DHCP pools on both the Main Campus router and the Second Campus router to automatically assign IP addresses to hosts in their respective VLANs.

· Each router handles DHCP for its local VLANs, ensuring devices in each building receive the correct IP

management.

Main Router (Main Campus Router)

Connects:

The Main Building’s Layer 3 Switch

The Second Building’s Layer 3 Switch

A separate Mail Server

Routing Protocol: Configured RIP Version 2 for dynamic routing between buildings and the mail server router.

Serial Connection

Used serial connections between routers (DCE/DTE) to simulate WAN-like links and enable inter-building routing.
