TRAINEE PACKET TRACER
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
ANALYST PACKET TRACER
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.
Router-on-a-Stick · Dot1Q · Subinterfaces · Default Gateway
ANALYST BROWSER LAB
LAB 3 — STP ROOT BRIDGE ELECTION
Walk through the 4-step STP algorithm, then drill it in an interactive browser lab. Quiz mode, step-by-step walkthrough, and a sandbox where you change priorities and watch STP recalculate.
STP · Root Bridge · Port Roles · Port Costs · BPDU
ANALYST PACKET TRACER
LAB 4 — RAPID SPANNING TREE (RSTP)
Same triangle as Lab 3, faster recovery. Configure 802.1w / Rapid-PVST+ on three switches and watch a link failure reconverge in under a second.
RSTP · 802.1w · Rapid-PVST+ · PortFast · BPDU Guard · Edge Ports
ANALYST PACKET TRACER
LAB 5 — OSPF SINGLE AREA
Multilayer switch and one router, three PC LANs and a server segment. Configure OSPFv2 area 0, watch the adjacency reach FULL, and verify routes appear in every table.
OSPF · Area 0 · Router-ID · LSDB · Adjacency · L3 Routed Ports
ANALYST PACKET TRACER
LAB 6 — STATIC & FLOATING STATIC
Six routers, four LANs. Build full reachability with nothing but ip route, then watch your AD-100 statics beat the pre-configured OSPF on a contested link. Bonus: flip the contest with a floating static at AD 120.
Static Routes · Default Routes · Administrative Distance · Floating Static · OSPF AD Compare
ANALYST PACKET TRACER
LAB 7 — ETHERCHANNEL (PAgP / LACP / STATIC)
Three EtherChannel modes in one topology. Build a routed PAgP /30 between distribution switches, an LACP trunk between access switches, and a Static bundle on the third — then ping end-to-end through all three.
EtherChannel · LAG · PAgP · LACP · Static · L3 Port-Channel · Inter-VLAN
ANALYST PACKET TRACER
LAB 8 — OSPF MULTI-AREA
Six routers, five OSPF areas. Backbone area 0 with R100/R200, three ABRs (R10/R20/R30) using loopback router-IDs and network statements, and R40 configured in modern interface-mode. Watch type-3 summary LSAs leak between areas in show ip ospf database.
OSPF · Multi-Area · ABR · LSA Types · Loopback Router-ID · Interface-Mode OSPF
ANALYST PACKET TRACER
LAB 9 — CDP & LLDP NEIGHBOR DISCOVERY
Four devices, two discovery protocols. Observe CDP, manipulate it globally and per-interface, then enable LLDP across the topology and compare. Learn why CDP doesn't cross switches, why you turn it off on edge interfaces, and exactly what an attacker harvests from one frame.
CDP · LLDP · 802.1AB · Neighbor Discovery · Security · Edge Hardening
ANALYST BROWSER LAB
LAB 10 — ACL EVALUATION (STANDARD, EXTENDED, NAMED)
Top-down, first-match-wins, implicit deny. Read sample ACLs by hand, then build standard, extended, and named ACLs from CLI templates. Drill the matching logic on randomized packets in the browser drill — Standard, Extended, and Mixed modes.
ACL · Standard · Extended · Named · Wildcard Mask · access-class · CCNA Domain 5
ANALYST PACKET TRACER
LAB 11 — 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 12 — FULL CCNA TOPOLOGY
VLANs, trunking, inter-VLAN routing, OSPF, NAT, ACLs all in one topology. Exam-style, no handholding.
Everything · Comprehensive · Exam-ready
◌ COMING SOON
[ ★ WHAT'S COMING ]
More CCNA labs are in the pipeline — NAT overload and a full exam-style topology that ties everything together. 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._
