LABS_
Free Packet Tracer lab files for CCNA practice. Every lab comes with a topology diagram, IP addressing table, and step-by-step tasks. Download, build it, break it, understand it.
TRAINEE — single concept, guided
ANALYST — multi-concept
ENGINEER — complex, less guidance
Need to sharpen your subnetting before you start? Practice network, host, and broadcast calculations with random questions.

LAB 1 — VLAN SEGMENTATION
Two switches, six PCs. Students on VLAN 10, Staff on VLAN 100, trunk between switches. Configure from scratch and verify isolation with ping tests.
VLANs · Access Ports · Trunk Ports · 802.1Q · Portfast

LAB 2 — INTER-VLAN ROUTING
Add SW3 and a router. Configure dot1q subinterfaces on R1 to route between Student and Staff subnets. Two parts — isolation then routing.

LAB 3 — STP ROOT BRIDGE
Build a redundant switched topology and watch STP elect a root bridge, assign port roles, and block redundant paths.
STP · Root Bridge · Port Roles · BPDU · show spanning-tree

LAB 4 — OSPF SINGLE AREA
Configure OSPF across three routers, verify adjacency, and understand how LSAs build the link-state database.
OSPF · Router ID · Adjacency · LSA · show ip ospf neighbor

LAB 5 — NAT OVERLOAD (PAT)
Configure NAT overload to allow multiple inside hosts to share a single public IP. The most common NAT in the wild.
NAT · PAT · Inside/Outside · ip nat pool

LAB 6 — FULL CCNA TOPOLOGY
VLANs, trunking, inter-VLAN routing, OSPF, NAT, ACLs all in one topology. Exam-style, no handholding.

[ ★ WHAT'S COMING ]
More CCNA labs are in the pipeline — STP, OSPF, NAT, and a full exam-style topology. Every lab gets a matching lab doc that walks through the why, not just the how. If there's a topic you'd like a lab for, send it through on the contact page._
