EXTERNAL BROWSER LAB
SWITCHLAB — LEARN NETWORKING IN YOUR BROWSER A free, install-free platform for practicing networking interactively in the browser. A solid companion to the Packet Tracer labs below when you just want to drill switching concepts without firing up a simulator. Browser-based · Switching · Hands-on · No install

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

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

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

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

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.

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

LAB 11 — PACKET FLOW & ENCAPSULATION Trace one packet host → switch → router → router → switch → server: ARP, MAC learning, encapsulation/decapsulation and TTL at every hop — then the TCP 3-way handshake, UDP, FTP active/passive and DHCP. Driven in the live packet visualizer, with an optional Packet Tracer simulation-mode build. Encapsulation · ARP · TTL · TCP/UDP · DHCP · CCNA Domain 1

LAB 13 — 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._

★ PACKET TRACER LABS — FAQ

Are these CCNA Packet Tracer labs free?

Yes — every lab here is free to download. No account, no signup, no paywall. Grab the .pkt file and open it in Cisco Packet Tracer.

Do I need Cisco Packet Tracer to run them?

Yes. The labs are .pkt files, so you'll need Cisco Packet Tracer — itself free from the Cisco Networking Academy. Download Packet Tracer, open the lab file, and start configuring.

Do the labs come with a walkthrough or answers?

Every lab has a matching lab doc — a full written walkthrough with the topology, IP addressing table, step-by-step tasks, the exact IOS commands, and the reasoning behind each step. Try it yourself first, then check your work against the doc.

What CCNA 200-301 topics do the labs cover?

VLANs and trunking, inter-VLAN routing (router-on-a-stick), STP and RSTP, single- and multi-area OSPF, EtherChannel, CDP/LLDP, and static/floating routes — each one mapped to the official Cisco 200-301 blueprint on the CCNA Study Hub.

Are these good for CCNA 200-301 exam practice?

Yes. The labs are built around the 200-301 blueprint and ramp from guided (Trainee) to exam-style with no handholding (Engineer), so you practice hands-on config the same way the exam tests it.
