Routing & VPN Basics Lab
Posted · Updated
Designed and operated a multi-site network simulation lab to practice routing fundamentals, VPN tunnel configuration, and connectivity troubleshooting, reinforcing Cisco networking concepts through hands-on experimentation with both static and dynamic routing protocols.
Project details
Configured multi-branch network topologies simulating enterprise WAN connectivity, including static routing paths for predictable traffic patterns and dynamic routing protocol scenarios that demonstrated how networks adapt to link failures and topology changes in production environments.
Implemented VPN tunnel configurations across isolated network segments, practicing split-tunnel, full-tunnel, and failover scenarios to understand how encrypted connectivity is established and maintained between geographically separated sites.
Captured detailed troubleshooting logs, packet traces, and failover behavior records for each lab scenario, building a documented reference library of common routing and VPN issues along with validated resolution steps for repeatable lab exercises.
Bridged theoretical networking concepts with practical implementation by systematically working through real-world scenarios such as routing table convergence, asymmetric path detection, and VPN re-establishment after link failures, using both Packet Tracer simulations and physical lab equipment.
Work Context: At Pures College (IT Systems Support and Computer Instructor, 2024–2025), I used these routing and VPN exercises to guide learners through structured troubleshooting and network behavior analysis.
Current Implementation: I continue extending these scenarios in my personal lab to test failover handling and connectivity recovery patterns.
