Overview
Cisco Modeling Labs (CML) is a networking simulator, and the preferred option for Cisco labs on this site.
Unlike other emulation options (like eveNG, Packet Traces, and GNS3), CML comes with switch and router software images, as well as various server nodes.
CML 2.1 can be deployed as a Virtual Machine, or as bare-metal.
