Enterprise Networking Project 9: Financial Institution Network Design and Implementation

Introduction

• Importance of the project: Enterprise Networking Project 9 focuses on a financial institution.
• Previous Projects: Links to previous projects from 1 to 8 will be shared in the video description.
• Complexity Level: Project 9 is more complicated than the previous projects.

Project Overview

Case Study: Jubilee Financial Services Limited (JFSL)

• Location: Nairobi, Kenya.
• Operational Structure: 11-story building, with operations primarily on the 7th and 8th floors.
• Departments: 5 departments - Human Resources (HR), Customer Service (CS), Marketing (MK), Legal Management (LM), Information Technology (IT).
  • 7th floor: HR, CS, MK (40 users/devices each)
  • 8th floor: LM, IT (20 users/devices each)

Network Infrastructure Requirements

• Network Management: Current infrastructure managed by Infinity Systems Kenya; JFSL aims to manage its own.
• ISPs: Subscription to two ISPs (Safaricom and JTL) for redundancy and load balancing.
• Equipment Purchased:
  • Two Cisco Catalyst 2911 routers, one for HQ, one for server side.
  • Voice over IP gateway router.
  • Two multilayer switches and six access switches for the departments.
• Security Requirements: Each department on a separate network segment.
• Access Control List (ACL): Used to dictate user access.

Project Requirements

Main Requirements

1. Design Tool: Use Cisco Packet Tracer for design and implementation.
2. Hierarchical Design: Must provide density at every layer.
3. Wireless Network: Each department requires a wireless network for users.
4. Voice over IP: Each department to have IP phones.
5. Subnetting: Calculate correct number of IP addresses for each department.
6. Basic Settings: Configure basic settings for all devices, including hostnames, passwords, etc.
7. Routing Protocol: Use OSPF for routing.
8. Security Configuration: Configure port security, SSH, and Access Control Lists.
9. VoIP Configuration: Configure voice over IP settings and dial numbers.
10. Testing: Ensure all configurations work as expected.

Network Design Steps

• Network Beautification: Visual design of the network layout.
• Basic Settings Configuration: Hostnames, passwords, and disabling unnecessary features.
• VLAN Configuration: Set up VLANs for data and voice.
• DHCP Configuration: Set up DHCP for device IP allocation.
• Routing Configuration: Implement OSPF routing.
• Security Configuration: Implement switch port security features.
• IP Addressing and Subnetting: Properly address devices based on department needs.
• Testing Communication: Verify that all network devices can communicate.

Configuration Details

Layer 3 Switches and Routers

• VLAN Configuration:
  • Data VLANs for each department - HR (10), CS (20), MK (30), LM (40), IT (50).
  • Voice VLAN (120) for all IP phones.
• DHCP Pool Configuration: Each department to have its DHCP pool based on their assigned networks.
• IP Addressing Scheme:
  • HR department: 192.168.20.0/26
  • CS department: 192.168.20.64/26
  • MK department: 192.168.20.128/26
  • LM department: 192.168.21.0/27
  • IT department: 192.168.21.32/27

VoIP Configuration

• Telephone Service Configuration:
  • Assign dial numbers in the format 4XX.
  • Enable DHCP for IP phones.

Security Features

• ACL Configuration for SSH Access: Limit SSH access to IT department only.
• NAT Configuration: For external communication.

Testing and Verification

• Ping Tests: Ensure devices can ping each other and reach the DHCP server.
• VoIP Functionality Tests: Check calling capabilities between IP phones.
