5 / 50 Labs
STEP 01
Network Architecture Overview (The Big Picture)
Understand what network we are building, the design model used, and how this single lab will cover the full CCNA syllabus.
Covers: HO + Branch • three-tier concept • collapsed core (ROAS)
STEP 02
Add Devices (Router, Switch, PCs)
Add the key devices and learn what each one does in the network.
Covers: router vs switch • access layer • layout
STEP 03
Add Serial ports to R2 and R3
Prepare for WAN links by adding serial interfaces/modules in Packet Tracer.
Covers: serial interfaces • WAN readiness • modules
STEP 04
Cabling & Links (Access vs Uplinks)
Connect devices correctly and identify which links will become trunks/uplinks later.
Covers: cabling • interfaces • link purpose
STEP 05
Basic Device Setup (Hostnames, Passwords)
Do the base configuration so the lab is ready for VLANs, routing, DHCP, and security.
Covers: hostname • passwords • saving config
