Cisco Packet Tracer Project: Network Topology and Routing

This project involves the creation of a network topology and routing configuration using Cisco Packet Tracer. The primary goal of this project is to establish communication between various network devices, including routers, switches, servers, and end-user devices.

About the Project

The network topology consists of the following components and configurations:

• Routers: The project includes three routers. The connections between these routers are configured using the RIP routing protocol.
• Switches: switches are used to interconnect various devices within the network.
• Servers: The network includes DHCP, DNS, HTTP, and Email servers.
• Wireless Network: A wireless network is established using an Access Point (AP), connecting laptops and PCs wirelessly.
• PCs and Laptops: Different subnets contain PCs and laptops, some connected via wired and others via wireless connections.
• Printer: A single printer is included in the network, with its IP address manually configured.

Configuration Details

• RIP Routing: Dynamic routing between routers is enabled using the RIP protocol.
• DHCP: The DHCP server is configured to automatically assign IP addresses to devices in the network.
• DNS: The DNS server is configured to resolve domain names to IP addresses.
• HTTP: The HTTP server provides web services.
• Email: The Email server is configured to provide email services using SMTP/POP3/IMAP protocols.
• VLAN: VLAN configuration is implemented on the switches to isolate certain devices within the network.

Setup and Usage

1. Opening the Project in Packet Tracer:

   • Launch Cisco Packet Tracer.
   • Use the File > Open option to load the .pkt project file.

2. Verifying Network Functionality:

   • Ensure that each device has obtained the correct IP address.
   • Test connectivity by pinging between devices.
   • Check access to the HTTP server using web browsers.
   • Verify email server access with email clients.

3. Troubleshooting:

   • If connectivity issues arise, check the configurations on routers and switches.
   • Ensure the DHCP server is operational and assigning IP addresses correctly.
   • If DNS resolution fails, verify the DNS server configuration.
