CCNA FOUNDATION
Lab 01
Two networks, one connection
Connect a Cisco branch to a Huawei branch. Interfaces and hosts are ready; add a static route in each direction to deliver the first ping.
Hands-on network labs
Practise real network configuration in your browser.
Build the topology, type the commands, and watch every objective tick as the network comes up. 136 guided labs, from your first static route to vPC, VXLAN and inter-domain multicast.

Pick a track and work through it lab by lab
Each lab sets a goal, gives you a ready-made network, and checks your work from the simulated devices themselves.

A few labs to begin with
Open one, read the objectives, then launch it in the simulator.
CCNA · DEVICE ACCESS
Lab 09
Secure a Cisco router
Harden R1 the Cisco way: hostname, enable secret, console and VTY passwords, a banner and SSH with local users. Save when done.
MULTICAST · MSDP
Lab 94
Multicast: sources in another domain with MSDP
Two PIM sparse-mode domains each keep their own RP: R2 (2.2.2.2) for domain A, where SRC sends, and R3 (3.3.3.3) for domain B, where PC4 has joined 239.1.1.1. RP-B never hears about SRC, so PC4 gets nothing. Peer the two RPs with MSDP so RP-A announces the source in a Source-Active message and RP-B joins it across the border.
CCNP DC · vPC TROUBLESHOOTING
Lab 122
Troubleshoot: vPC peer-gateway and the router MAC
N1 (192.168.10.2, 192.168.20.2) and N2 (.3) route between VLAN 10 and VLAN 20 with plain SVIs, no HSRP. PC1 uses N2’s own address 192.168.10.3 as its gateway. PC1 and PC4 sit behind the same vPC on SW3, yet PC1 cannot reach PC4 (192.168.20.40). Find out why, and fix it in the vPC domain.
HUAWEI · VRP
Lab 07
Huawei VRP from the beginning
Both branch routers run Huawei VRP-style CLI. Configure static routes using system-view and verify two-way reachability.
CCNA / CCNP · ACL
Lab 08
Trace a policy failure
Routing already works. Create an ICMP deny policy on R1, observe the failed ping, then remove the binding and restore reachability.
