Lab auto-03 - Pushing Config with Netmiko
Your Python script enters config mode on three routers, provisions a loopback on each, verifies its own work, and saves to NVRAM using Netmiko's send_config_set(). All output captured from real IOS XE 17.18.

Lab auto-02 - Reading the Network with Netmiko
Scale the single-router Netmiko connection from Lab auto-01 to the whole topology: R1, R2, R3, and SW1 interrogated in one pass from one Python file. Read-only show command collection, captured live on IOS XE 17.18 in CML Free.
Lab auto-01 - Build Your First Network Automation Host
Build your first network automation host inside the lab: Alpine Linux, Python 3.12, and Netmiko 4.7 SSH into a Cisco IOS XE 17.18 router and pull live output. A free lab for CCNA Domain 6.
Lab ts-cap-01 - Troubleshooting Capstone: The Branch Office Outage
Three faults across three layers, one ticket: the branch is down. This CCNA troubleshooting capstone tests sequencing, fixing the lowest layer first, with every output captured on Cisco IOS XE.
Lab ts-sec-01 - Troubleshooting Security Tickets
Three security troubleshooting tickets on the five-node base topology: an ACL dropping traffic it should permit, a secured port shutting itself down, and a management ACL lockout. Fits CML Free, all output captured on Cisco IOS XE.
Lab ts-ips-01 - Troubleshooting DHCP and NAT Tickets
Three DHCP and NAT troubleshooting tickets on the five-node CCNA base topology. Each one fails quietly until you read the one counter or interface flag that gives it away. All output captured on Cisco IOS XE in CML Free.
Lab ts-ipc-01 - Troubleshooting OSPF Tickets
Three OSPF troubleshooting tickets that drill the key distinction: an adjacency that never forms versus a healthy adjacency with a missing prefix. Runs on the five-node base topology in CML Free, with real IOS XE output.
Lab ts-na-01 - Troubleshooting Switching and VLAN Tickets
Two hosts on the same subnet, both interfaces up, no reachability: the fault is one layer down. Three switching and VLAN troubleshooting tickets on the five-node CCNA topology, with every output captured from a real IOS XE switch.
Lab ts-nf-01 - Troubleshooting Connectivity Tickets (L1/L2/L3)
You inherit a broken network and a ticket that describes a symptom, nothing else. This free preview lab teaches the L1/L2/L3 fault localization method the CCNA tests hardest, on the five-node CML Free topology.
HSRP States: The 6-State Machine with show standby Output
All 6 HSRP states (Initial, Learn, Listen, Speak, Standby, Active), what drives the election, why preempt matters, interface tracking, and real show standby output.
CCNA 200-301 Mega Lab: The All-in-One Hands-On Campus
One 10-node CML topology that exercises the entire CCNA 200-301 hands-on blueprint: VLANs, STP, EtherChannel, HSRP, OSPF, NAT, DHCP, NTP and the security baseline, with real Cisco IOS XE captures.
VLAN vs VXLAN: The L2 Overlay, Demystified
VLAN vs VXLAN explained: a VLAN tags L2 segments, VXLAN encapsulates them across L3. The 4,094 limit, VTEPs, BGP EVPN, and when you actually need VXLAN.
