Packet Tracer

🛡️ Redundant Network Design with VLANs in Cisco Packet Tracer

I designed a fault-tolerant network using Cisco Packet Tracer to simulate an enterprise environment. The setup includes redundant links, VLANs, and EtherChannel to ensure high availability and efficient traffic management.

🖥️ Network Layout:

  • Network 1: VLAN 10, VLAN 20, VLAN 30

  • Network 2: VLAN 70, VLAN 80

  • Redundant Routers: Two ISR4331 routers for inter-VLAN routing and failover

🔁 Key Features:

  • Redundancy: Multiple links grouped into EtherChannel for load balancing and failover

  • VLAN Segmentation: Logical separation of traffic for better performance and security

  • Subnetting: Each VLAN has a unique IP range

  • Scalability: Easily expandable for future needs

✅ Why It Works:

  • High Availability: Redundant paths minimize downtime

  • Improved Performance: EtherChannel boosts bandwidth and link reliability

  • Structured Network: VLANs and subnetting enhance security and management

This project highlights how redundancy and VLAN management create a resilient, scalable network — essential for handling real-world demands.
