CCNP Route Control: Join Two Routing Domains
HQ runs OSPF and the company it bought runs EIGRP. Join them at the boundary router so both sites reach each other.

CCNP VRF & GRE: Two Tenants, One Router
Two tenants share one edge router. Give each its own routing table, so both can use the same service address.

CCNA L3 Switching: Retire the Router-on-a-Stick
The router-on-a-stick is gone. Turn the distribution switch into the gateway for both VLANs.

CCNA Break/Fix: The Branches the Core Cannot See
Daily CCNA troubleshooting drill: Two branches can ping the core over their transit links, yet the core does not learn any branch routes. Your job is to trace how OSPF is enabled on each device, isolate why the core’s routing table is missing the branch LANs and loopbacks, and bring both branches into the correct OSPF area without changing how the core enables it.

CCNA Break/Fix: The Trunk That Carries Only Some VLANs
Your team supports a small campus access layer: two switches, one 802.1Q trunk. The help desk reports VLAN 20 users cannot reach their peers while VLAN 10 users can, and both ends read up and trunking. Campus design: VLANs 10 and 20 are the only VLANs any trunk carries; every trunk's native VLAN is 999.

DHCP Snooping Trust Boundary
Harden the Layer-2 access edge by enabling DHCP Snooping on a single access switch and placing the trust boundary only toward the legitimate DHCP server/gateway. Validate with show commands and end-host connectivity.

CDP Neighbor Discovery and Edge Suppression
Enable Cisco Discovery Protocol (CDP) on R1 to map directly-connected Cisco neighbors while suppressing CDP advertisements on the untrusted management-edge interface. Routers are directly cabled for true CDP adjacency and also share a common management LAN via SW1 alongside an Alpine MGMT host.

CCNA L1: Interface Addressing and Verification
Beginner CCNA lab (1 of 10) focused on configuring and verifying IPv4 interface addressing on Cisco IOS routers. Learners assign given /24 addresses to two router interfaces and validate directly-connected reachability. No routing protocols or static routes are configured in this lab.

CCNA NTP Client: Sync to an Authoritative Server
Beginner CCNA NTP lab. Two IOS routers share a single /30 link with no routing. Configure R1 as an authoritative NTP master at stratum 3 and point R2 to R1 as its NTP server. Verify using show ntp associations, show ntp status, and show clock. Emphasis: deterministic config — grading checks the presence of ntp master 3 on R1 and ntp server 10.0.0.1 on R2, not live convergence.

CCNA: SSH Access Fundamentals on R1
Bring up secure remote management (SSH) on a single Cisco IOS router using a dedicated management LAN. You will configure the deterministic set of running-config lines that enable SSH with a local admin account, restrict VTY to SSH, and verify from a Linux workstation. RSA key generation is performed as an exec step and is not graded; the grading focuses on the presence of the configuration lines that make SSH functional and secure.

eBGP Fundamentals: The First Peering
Build your first external BGP (eBGP) peering between two routers in different autonomous systems over a /30 point-to-point link and exchange one /24 prefix from each side using Loopback0. The topology is intentionally small yet realistic, with two edge routers (AS 65001 and AS 65002) and three Alpine hosts for basic reachability checks and operator context. You will configure deterministic BGP neighbors, originate prefixes with exact-match network statements, and validate reachability and route installation using standard IOS and Linux tools. This is Lab 1 of 10 in the CCNP-aligned BGP Fundamentals series and sets the foundation for later labs on iBGP, route filtering, and path selection.

EIGRP Fundamentals: First Adjacency & Route Exchange
Bring up EIGRP in AS 100 between two routers over a /30 transit and advertise a single LAN. Verify the first adjacency forms and that R2 learns R1's LAN via EIGRP. Includes realistic end hosts on a shared LAN for path testing.
What's unlocked, and what's free
Subscription access, and the labs that need none.
A subscription unlocks every lab on this page for as long as it's active — the whole daily back catalogue, not just the labs published after you join, plus every series lab. Bundles and study paths aren't sold separately; the subscription is the only plan.
Free labs need no subscription at all: every lab you can build and grade without one is the sample, plus the opening lab of each series.
