So, here it is... I'm not going to ask you how to set up a lab or what resources are available since they are already in the sticky of the form. I already have Olive working for GNS3.

I already have the free materials (PDF, Juniper online courses, and CBT Nuggets). All I basically want to know for those of you that have passed the JNCIA is how long did you study? How long did it take to study for those of you that already held a CCNA/CCNP?
My employer is wanting me to get certified. I don't have really much Juniper experience. We do have access to some of the bigger juniper rigs on the service provider that I'm employed by. I know some basic show commands but that's about my level of experience on the Juniper side.
