Technical question on networking

[GGlow]

Hi,

I am new to networking, but I have a question about setting up a home lab to learn routing and switching.  I would like advice on whether I should prioritize real hardware or if GNS3/Packet Tracer is sufficient for hands-on learning.

You can learn much from using software based simulators (like PT - good for CNA level) or emulators (like GNS3).  I suggest starting with software.

At some point, it's nice to work with hardware, current gen hardware and current IOS software, can be a might expensive.

There's much that can be learned on out-of-date platforms, but they're just that, i.e. out-of-date.

BTW, GNS is great, but obtaining IOS images for it can be difficult, and the devices it support, may also be out of date.

Cisco, I believe, now provides a 5 node version of CML, "free".  It's software, is fairly close to current, and pretty full featured, however, it can be a resource hog on the platform it runs on.

Yes, start with PT before CML and GNS. PT is ideal for learning basic networking fundamentals and basic IOS for CCNA level exam. It enough to pass CCNA exam but u must pay attention to a few things (differences) between PT and what is described as "real-world behavior" mentioned in books. 

also, you should go to CLN https://learningnetwork.cisco.com/s/ for learning and studying tips, exams info, etc

Hello,

As other have mentioned PT is a great start. If you are fortunate to be working in the field then you will also have real equipment available to you.

PT is fine for hands on learning as the technology is the same regardless of the equipment hardware/software. You would just be limited on some functionality and may run into a weird bug every now and then. But that's the great thing about learning

Good luck in your studies!

Packet Tracer is totally fine for CCNA-level practice. As you progress and want a more realistic experience, try GNS3 or some real equipment if you can. For now, focus on mastering the basics, Packet Tracer will cover everything you need early on.

@GGlow Personally I would opt for packettracer unless you can get the images for the devices, the other emulators aren’t worth the trouble imo. If you wanted try CML, the five node free version is ideal for your labs and everything is included https://developer.cisco.com/docs/modeling-labs/cml-free/

You can even use CML in a cloud solution provided by DevNet as they have many free sandboxes including CML https://developer.cisco.com/site/sandbox/ the always on routers and devices are also get for quick access hands on as you get use to navigating around the command line and also the controllers such as catalyst centre.
