With any learning journey related to technology there is no two thoughts about the importance of hands-on lab. And all the time it boils down to the cost of having own home labs, if you are working in environment where can get few spare its great but most of time that is not case so we tend to find some cheaper solutions.
One of the reason today more and more people are getting in market with certifications is virtualization whether its emulating Cisco or Juniper router or running multiple OS(Microsoft, Linux) on single machine. And GNS3 is excellent tool to virtulize/emulate Cisco routers, but when I start learning Juniper I found it bit hard on how to emulate Junos as it runs on free BSD and me having no knowledge at all with linux find difficult to emulate but finally with help of our friend Google I am able to run Junos in GNS3 and build topologies to start with.
Now the question is how far I can go with Junos Olive without having physical router in my study plan. Well at this point I really don't know :). I heard few things doesn't work in Jonus olive. So I did little bit research on getting physical routers. Or Even getting to that first look at what certifications does juniper offers.
Above link shows Juniper offers three major tracks Routing and Switching Enterprise, Routing and Switching Service Provider and Security along with some technology specific tracks. In major tracks you start with Associate level (JNCIA) and go on all the way to expert level (JNCIE). And this is where you see whether you need to have physical lab what kind of exact products you need to add in your lab.
This is just a short description on Juniper learning and possible options of hands-on labs.
I will be creating video on how to emulate Junos and making it work with GNS3. A lot is already available on internet you can do Google yourself my method may be the same like others but this will be my approach on running Junos olive.
