Downloadable Cisco Packet Tracer labs for the CCNA, built in my home lab and verified in Cisco Packet Tracer 9.0.1. Each lab is a troubleshooting ticket: a broken .pkt file with a symptom and no hints, a working solution .pkt, and a walkthrough built from real Packet Tracer output.
Available Packet Tracer labs
- DHCP relay ticket: VLAN 20 users get no IP address: router-on-a-stick on an ISR4331, a 2960-24TT switch and a Server-PT DHCP server in VLAN 99. Find out why VLAN 20 gets no lease while VLAN 10 works. Free with a PingLabz account.
More tickets are on the way. They'll be added to this page as each one is built and verified.
How the lab files work
- Each lab post is public: the ticket, the topology and the addressing are open to everyone.
- The .pkt downloads and the full walkthrough unlock with a free PingLabz account.
- The files open in Cisco Packet Tracer 9.0.1. Each download is a .zip with the .pkt and a short README.
- Where Packet Tracer behaves differently from real IOS, the lab post says so.
