You may create your own LABs using "packet-tracer", which you may get without costs from cisco. There was also a thread about free ICND1 labs here: Good Free Labs for ICND1. If you search for yourself, you may find much more. Aside from packet-tracer, there are also GNS3 and eve-ng as networksimulators, but you need original cisco firmware images to simulate cisco devices ...
Hello Juergen ,
Thank you so much for the clarification. I was under the impresion that there will be labs for this part of the book as well , but couldn't find them . I will do my own labs for this part in packet tracer and also go thru some of the free once that you suggested .
Have a nice day,
