01. The Problem & Engineering Challenge
Simulating enterprise-grade peer-to-peer data sharing while strictly maintaining VLAN boundary security and preventing broadcast packet flooding.
02. Architectural Solution
Configured virtualized Cisco router instances in GNS3 with sub-interface routing, Access Control Lists (ACLs), and packet flow validation in Wireshark.
Key Deliverables
- ›Complete enterprise topology emulation file
- ›IP address scheme documentation & routing tables
- ›Packet capture logs with no leakage observed between segmented VLANs in lab captures
03. Technical Decisions & Tradeoffs
Segmented VLAN Subnetting
Isolated workstation traffic from sensitive server clusters.
Wireshark Protocol Analysis
Audited TCP handshake efficiency and dropped unauthorized ICMP packets at boundary switches.
