IP Addressing & Subnetting
IPv4 subnetting and VLSM, IPv6 addressing (SLAAC/EUI-64), and connectivity verification.
Graded, hands-on Cisco labs grouped by topic — CCNA fundamentals through CCNP multi-area OSPF, ACLs and VLANs.
Every bundle below is included with a subscription — the only plan we sell. See plans.
IPv4 subnetting and VLSM, IPv6 addressing (SLAAC/EUI-64), and connectivity verification.
Ten hands-on labs building VLAN segmentation from the ground up — access ports, VLAN databases, voice/data separation, and verification.
Trunk configuration, allowed/native VLANs, DTP behavior, and trunk troubleshooting.
Ten hands-on labs routing between VLANs — router-on-a-stick, subinterfaces, SVIs on a layer-3 switch, and gateway verification.
Root election, port roles/costs, PortFast/BPDU Guard, Rapid-PVST, and loop troubleshooting.
LACP/PAgP/static bundles, layer-2 and layer-3 port-channels, load balancing, and bundle troubleshooting.
Directly-connected/recursive next-hops, default and floating static routes, IPv6 statics, and path verification.
Progressive hands-on OSPFv2 labs — from a first single-area adjacency through DR/BDR election, multi-area design, route summarization, stub areas, authentication, and a troubleshooting capstone.
HSRP virtual gateways, priority/preempt, interface tracking, MD5 authentication, timers, HSRPv2, multi-group load-sharing, and VRRP.
Server pools, exclusions, reservations, relay (ip helper-address), and lease troubleshooting.
Static NAT, dynamic pools, PAT/overload, port forwarding, and translation troubleshooting.
Master/client/peer, authentication, stratum behavior, and time-sync verification.
Each bundle is a sequenced set you work through in order.
Every lab runs on CML free-tier (5 nodes or fewer) and is included with a subscription — the only plan we sell. See plans.
A sequenced set of graded Cisco Modeling Labs on one topic. Every lab is a real CML topology you build on Cisco IOS and then submit for automatic grading against the answer key. Open any bundle to see its full lab list and learning objectives.
A subscription includes them — every lab in every bundle, for as long as it's active. Bundles aren't sold separately any more. If you bought one before, nothing changed: it stays downloadable and gradable, permanently.
A bundle is a fixed set of labs on one topic, worked through in order; the daily is a fresh graded lab each day. One subscription unlocks both — every bundle lab, and the whole daily back catalogue, not just the labs published after you join.
You need somewhere to run the labs. Every lab is built for Cisco Modeling Labs on free-tier images (IOL, IOL-L2, IOSv) and imports in one click — the getting-started guide covers free ways to run CML.
