CCNA labs: hands-on Cisco IOS practice in your browser
The fastest way to build the muscle memory the CCNA exam rewards. Describe a network in plain English and get a fully cabled, configurable topology in seconds — then configure and verify it with real Cisco IOS. No Packet Tracer install, no physical routers, no cost to start.
How the labs work
Traditional CCNA lab tools make you drag every router, switch, and cable onto a canvas before you can type a single command. Securedy Labs flips that around:
Type a topology in plain English — for example, “two switches with VLAN 10 and 20 and a router-on-a-stick” — and the AI builds a complete, cabled network with valid addressing.
Open any device’s terminal and run real Cisco IOS. Enter configuration mode, set up OSPF, assign VLANs, write ACLs, and save with copy running-config startup-config.
Run show commands and ping across the topology. Reachability is simulated hop-by-hop through the actual packet path, so a misconfigured ACL or shut interface fails exactly like real gear.
CCNA lab topics covered
Labs span every hands-on domain of the CCNA 200-301 blueprint. A few of the topologies you can generate and configure:
- ·OSPF single & multi-area
- ·Static & default routing
- ·Inter-VLAN routing (router-on-a-stick & SVI)
- ·IPv6 addressing & routing
- ·HSRP first-hop redundancy
- ·VLANs & 802.1Q trunking
- ·Spanning Tree (STP/RSTP)
- ·EtherChannel (LACP/PAgP)
- ·Port security
- ·CDP & LLDP discovery
- ·DHCP server & relay
- ·NAT / PAT
- ·Standard & extended ACLs
- ·SSH & device hardening
- ·DHCP snooping & Dynamic ARP Inspection
A sample OSPF lab
Ask for “three routers running OSPF area 0 in a triangle, each with a LAN,” and you can immediately verify your work the way the exam expects:
R1# show ip ospf neighbor Neighbor ID Pri State Address Interface 2.2.2.2 1 FULL/ - 10.0.12.2 GigabitEthernet0/1 3.3.3.3 1 FULL/ - 10.0.13.2 GigabitEthernet0/2 R1# show ip route ospf O 192.168.2.0/24 [110/2] via 10.0.12.2, GigabitEthernet0/1 O 192.168.3.0/24 [110/2] via 10.0.13.2, GigabitEthernet0/2
Pair your lab time with practice questions and follow the study guide to cover every domain in order.
No installation, works on any device
Because everything runs in the browser, you can lab on a laptop, a Chromebook, or a tablet — anywhere you have a few spare minutes. Your topologies save to your account with full version history, so you can pick up exactly where you left off.
