Want the full lab as a free PDF? Download it now, no cost. It’s a real 7-router BGP project you automate end to end with Python. No manual CLI. Grab the file, open GNS3, run one script, watch BGP converge across 4 autonomous systems.

Here’s the short version. This free download hands you a working network automation project, not a theory dump. You get the topology, the IP plan, the full Python script, and the verification commands. Build it once and you’ve got a portfolio piece hiring managers actually recognise.

What’s inside the free PDF?

One file. Everything you need to build and automate the lab.

  • The full topology – 7 Cisco routers across AS100, AS200, AS300 and AS400
  • Complete IP addressing plan – every interface, loopback and subnet mapped out
  • The whole Python + Netmiko script – copy, paste, run. It configures all 7 routers for you.
  • eBGP and iBGP design – update-source, ebgp-multihop, next-hop-self, full-mesh iBGP
  • OSPF as the IGP inside AS400 – so your iBGP loopback sessions actually form
  • Step-by-step setup – Python, VS Code, GNS3, and how to pull console ports
  • Verification and troubleshooting – the exact show commands and the fixes for common BGP errors

Print it, keep it on a second monitor, or follow it click by click. The free lab guide works either way.

Why bother learning network automation?

Because the pay gap is real, and it’s growing.

The average network automation engineer in the US earns about $130K a year (Salary.com, 2026). Automation skills add a 15% to 30% premium over a traditional network engineer at the same level, and Python plus a tool like Ansible or Terraform can add $15K to $30K to an offer.

The demand side is just as loud. Gartner projects that 30% of enterprises will automate more than half of their network activity by 2026, up from under 10% in 2023. Python now shows up in roughly 22% of network engineer job postings. Translation? “Knows BGP” is table stakes. “Automates BGP with Python” is what gets you hired.

This free BGP lab sits right at that intersection. Real routing protocol, real automation, one project.

Who is this free lab for?

  • CCNP and CCIE students who want a hands-on BGP project, not just flashcards
  • Network engineers moving from CLI into Python and Netmiko
  • Career switchers who need one strong portfolio project to show
  • Anyone studying for a routing exam who learns better by building

If you’ve configured a router by hand before and you’re curious what “zero-touch” really means, start here. Get the PDF free and see it work.

What you’ll actually build

The lab is a multi-AS BGP network, the kind that mirrors how the internet is stitched together.

  • 4 autonomous systems connected through eBGP border routers
  • Full-mesh iBGP inside AS400 across R4, R5, R6 and R7 (6 sessions total)
  • OSPF Area 0 carrying loopbacks so those iBGP sessions can form
  • Best-practice BGP attributes applied consistently across every device
  • One Python script that pushes IP config, static routes, OSPF and BGP to all 7 routers, then saves the config

You run it once. Ninety seconds later BGP is converging and routes are crossing AS boundaries. That’s the whole point of automation. Hours of typing become one command.

How to use the download

  1. Grab the free PDF from the button above
  2. Install Python, VS Code and GNS3 (the guide walks you through it)
  3. Build the 7-router topology in GNS3
  4. Paste the automation script and run it
  5. Verify with show ip bgp summary and watch every neighbor hit Established

That’s it. No paywall, no trial. It’s a free download you keep.

Frequently asked questions

Is the BGP lab PDF really free?
Yes. It's a 100% free download. Add your email and the PDF is yours to keep, print and reuse.
What's in the free download?
The full BGP Multi-AS topology, the IP addressing plan, the complete Python and Netmiko automation script, OSPF and BGP config, plus verification and troubleshooting steps.
Do I need to pay for any tools?
No. Python, VS Code and GNS3 are all free. The lab runs on free software end to end.
What will I learn from this free lab?
How to automate a real 7-router, 4-AS BGP network with Python and Netmiko, how eBGP and iBGP differ, why OSPF supports iBGP loopback sessions, and how to verify BGP convergence.
Is this good for CCNP or CCIE prep?
Yes. It's a strong hands-on project for anyone studying routing at the CCNP or CCIE level, and a solid portfolio piece for interviews.
