Ten hands-on DHCP labs — server pools, exclusions, reservations, relay (ip helper-address), and lease troubleshooting — on CML free-tier (5 nodes or fewer).
Build a single-scope DHCP server on an IOS-XE router and verify two Alpine Linux clients lease addresses dynamically across a pure Layer-2 switch. Configure only the canonical pool (network + default-router). Verify leases from the router and from each client.
View lab detailsConfigure an IOS-XE router as a DHCP server with a correctly scoped pool and an excluded-address range that protects the gateway and a reserved static server (.10). Two Alpine clients obtain addresses dynamically from the remaining range (starting at .11). Verify leases, confirm the excluded count, and ensure the reserved static never appears as a DHCP binding.
View lab detailsConfigure an IOS-XE router as a DHCP server delivering a complete, production-grade option set (gateway, DNS servers, domain suffix, explicit 8-hour lease) to two Alpine Linux clients over a pure L2 access switch. Validate that clients obtain dynamic addresses in-scope and that /etc/resolv.conf reflects the delivered DNS and domain options. The graded outcome is the deterministic router DHCP configuration — not the clients’ dynamic addresses.

10 hands-on, auto-graded CCNA labs spanning 17 topics — each one a real Cisco Modeling Labs scenario you build on Cisco IOS. It's a one-time $29.99 and every lab is yours to keep forever.
A one-time purchase — $29.99. Buy once and own every lab in the bundle permanently; it's separate from the daily-lab subscription, so there's nothing recurring.
Yes — each lab is a Cisco Modeling Labs (CML) topology you import and build on real Cisco IOS, and the CML free tier is enough. You download the topology and lab guide, then build it yourself.
Every lab ships as a problem to solve. You build it in CML, then submit your config to grade it against the answer key — you get a pass/fail on each objective, so you know exactly what's right and what to fix instead of guessing.
CCNA. The labs are sequenced to build the hands-on configuration and troubleshooting skills CCNA candidates are expected to demonstrate on real gear.
Configure a centralized DHCP server on an IOS-XE router and relay DHCP from a remote branch LAN using ip helper-address on a branch router. Verify leases, helper configuration, and end-host reachability across a routed path.
Build and verify two independent DHCP address pools on a single Cisco IOS router, each serving a different LAN. Two Alpine Linux clients obtain leases from their respective pools via directly attached access switches. You will configure the pools, excluded addresses, default gateways, DNS, and domain names, then verify with IOS show commands and Linux tools. The focus is deterministic router DHCP configuration; clients lease dynamically and are verified rather than graded.
View lab detailsConfigure an IOS router as a DHCP server and have another IOS router obtain its uplink address dynamically via DHCP on a shared LAN. Validate the lease from both the client and server perspectives and test reachability from attached hosts.
View lab detailsConfigure a Cisco IOS router as a DHCP server with a general LAN pool and a per-host manual binding (reservation) so that CLIENT-A always receives 172.20.10.5 based on its MAC, while CLIENT-B receives a normal dynamic address from the same subnet. Verify with router show commands and Linux host tools. Focus strictly on DHCP: pool scope, excluded addresses, options, and a hardware-address-tied manual binding.
View lab detailsHands-on IOS DHCP server practice focused on validating pool state, inspecting conflicts, and fixing a real address conflict caused by a legacy static host on the LAN. You will verify server-side leases and exclusions, observe a conflict entry, then permanently exclude the static IP and clear the stale conflict so a client can obtain a clean address.
View lab detailsBuild a central DHCP service on an IOS-XE router and service two branch departments across a routed hop via DHCP relay. Configure two DHCP pools (SALES and SUPPORT) with proper options and excluded ranges on the HQ server, and enable ip helper-address on both branch LAN interfaces so clients obtain leases from the correct pool. Verify leases and bindings using Linux and IOS show commands, and confirm return-path reachability with prebuilt static routes.
View lab detailsAdvanced CCNA troubleshooting capstone for centralized DHCP across a relay. A centralized IOS-XE router (DHCP-SRV) serves the branch LAN behind BR-RTR via ip helper-address. The lab imports in a deliberately broken state: the DHCP pool scope and gateway are misconfigured on the server, and the relay configuration is missing on BR-RTR. Learners must diagnose using show outputs and Linux tools, fix all three discrepancies, and verify that two Alpine clients dynamically receive usable leases and can reach DHCP-SRV.
