GNS3 Networking Labs
250+ GNS3 labs give you hands-on access to various networking devices from popular vendors. These labs begin with preconfigured topologies and well-defined task objectives. Once the lab tasks are completed, a learner can view detailed solutions for each lab. GNS3-based labs are unlocked, meaning that users can modify the existing topology any way they wish or even use them as a sandbox environment for creating entirely new topologies for experimentation with networking protocols and features.
