Core Configuration of a Router and a Switch in Cisco Packet Tracer – Every Command Explained.

Berg IT Training – In this CCST and CCNA introductory-level video, I perform a line-by-line core configuration of a Cisco router and a Cisco switch using the command line interface (CLI) in Cisco Packet Tracer, explaining each command in detail and verifiying the effects of each command as we go.

We perform all the foundational commands discussed in Cisco’s CCNA: Introduction to Networks version 7 (CCNA 1).
