To get hands on experience with the real Cisco routers and switches, you can buy CCNA lab kits at affordable rates from Amazon or eBay.
The best thing about practicing with the real routers and switches is that you will get the feel of working with the actual hardware. However, if you are not necessarily preparing for an exam, simulators like GNS3 and Packet Tracer could still help you sufficiently practice without having to spend too much money on the real hardware. Moreover, these simulators are very easy to handle and practice. You can simply take your laptop with yourself and exercise the network topologies anywhere you want. Additionally, Packet Tracer’s mobile version is also available on the play store for downloads.
Ready-made Cisco lab kits from e-commerce websites like Amazon and eBay are also available for you to buy. Or you can buy individual routers and switches of different models and develop a lab of your own. Although developing a kit like this would cost you some money. But if you are seriously looking to create your own lab then you can try getting cheap hardware from recycling IT shops and stores. Moreover, once you are finished with your practice you can sell your kit to someone when it is no longer required.
