Cisco packet tracer vs gns312/10/2023 Candidates with experience have passed CCNA with well-designed practice tests only. It is true that experience plays a significant part in any certification exam. It is important to dispel the marketing hype and confusion that often surrounds CCNA lab training. CCNA 200-301: What Does It Really Require? The best lab training platform provide features, functionality, ease of use, and cost. It is often used in conjunction with a study guide or course. Lab training is a learn by doing approach for real-world experience with configuration of network topologies. This article compares lab training platforms available for CCNA and CCNP certification. This is suitable for both the senior engineers that prefer Mininets for its complex and comprehensive functions, as well as the engineers that prefer Containerlab for its flexibility.Selecting the proper lab training platform is key to preparing for Cisco certification. It allow the usage of Docker containers as hosts in emulated network topologies. The ultimate weapon: Containernet.Ĭontainernet is a fork of the famous Mininet but ulitizing the idea of Containerlab. Containerlab is flexible and easy to use, and it has gained popularity among network engineers and DevOps teams. It uses Docker containers to simulate network devices, and it provides a simple YAML-based syntax to define network topologies. Containerlab:Ĭontainerlab is a newer network emulation tool that is designed to create container-based network topologies. Mininet is customizable, and its performance is dependent on the underlying hardware resources. It is commonly used by network engineers and researchers to test and prototype network applications and protocols. Mininet hosts run standard Linux network software, and its switches support OpenFlow for flexible custom routing and Software-Defined Networking (SDN). ![]() Mininet is an open-source network emulator that allows users to create a virtual network within Linux environments. GNS3's GUI is very intuitive and easy to use compared to other emulation tools. Compared to other Emulation tools, the biggest advantage of GNS3 lies in its name "Graphical". ![]() It is widely used by network engineers for testing and troubleshooting complex network topologies. GNS3 supports a wide range of devices and provides a more realistic network emulation environment compared to Packet Tracer. ![]() GNS3 (Graphical Network Simulator 3):Īlthough named Network Simulator, GNS3 is actually a network emulator, which allows users to run real network operating systems (OS) such as Cisco IOS, Juniper Junos, and others on a virtual environment. Packet Tracer is a great tool for learning network design and configuration for Cisco devices, but it has limited support for deep hard-ware related features of those devices, as well as non-Cisco ones. It provides a graphical user interface (GUI) that allows users to design and simulate networks consisting of Cisco devices. Cisco Packet Tracer:īeing a Cisco-propietary network simulator, it is widely used by students to learn networking concepts, especially those related to Cisco's devices. Overall, Simulators are more simple and more suitable for education purposes, while Emulator is more suitable for the deployment and testing of production systems. ![]() In contrast, an emulator also tries to mimic all of the software and hardware features of the system within the system's own environment, then link these environment together as if they are linked in the real production systems. The difference is that a simulator is designed to mimic the behaviors and variables of the software of an actual system within the simulator's environment. Overall: Network Simulators vs Emulators.Ĭisco Packet Tracer, GNS3, Mininet, and Containerlab are all network simulation and emulation tools that are commonly used by network engineers and students to design, test, and troubleshoot network topologies.Īmong them, Packet Tracer is the only network simulation tool, while the rest are categorized as network emulators. Comparison of several famous network emulators and simulators from my experience.
