Course Outline
Introduction to Network Simulation with GNS3
- GNS3 architecture and its capabilities for design and testing.
- Comparative analysis: GNS3 versus physical labs and other simulators.
- Optimal hardware, OS requirements, and configuration recommendations.
Setting Up the GNS3 Workspace
- Installation of the GNS3 GUI and GNS3 VM.
- Integration of GNS3 with physical hardware and virtual machines.
- Leveraging Docker containers, network appliances, and auxiliary tools.
Constructing Enterprise Network Frameworks
- Layer 2 and Layer 3 network infrastructure components.
- Simulating multi-site WAN and data center environments.
- Representing cloud and hybrid architectures within GNS3.
Production Environment Replication
- Extracting configurations from active networks.
- Importing existing routing and switching configurations.
- Creating scalable testbeds populated with realistic traffic patterns.
Testing, Verification, and Documentation
- Techniques for traffic generation and fault injection.
- Automated testing scenarios, including BGP failover, QoS, and ACLs.
- Packet analysis and flow validation using Wireshark.
Tool Integration Strategies
