How much different is it working with Cisco vs Juniper hardware

Hello all,

I realize that this is in the Cisco section but I assume many of you have worked with Juniper as well. I currently work in a 100% cisco shop and am interviewing for a position at a company that has a mix of both Cisco and Juniper.

I'm CCNP certified and like to think I know Cisco hardware very well. How much different would it be to throw Juniper into the mix? I have had zero exposure to Juniper hardware. Is working in the command line much different between the two? Or is just a matter of slightly different syntax?

    JunOS is pretty easy to understand. Get the Junos for IOS Engineers ebook for free off of Amazon or the Juniper site. You can also run JunOS as a VM for some practice.

    I found it harder to learn the hardware side rather than the OS side. Overall though you can draw similarities (sup = RE, line card = FPC etc.) to ease your transition. Anyone who really knows the fundamentals shouldn't have much trouble applying them to another platform. Junos as a second language is a good primer.

    I have had some exposure to Juniper stuff from work. I can say that from the JUNOS point of view the command syntax structure is VERY similar. Infact there are many features I like better with JUNOS than with Cisco IOS. However there are some nuances too. I didn't like their 'syslog' as you have to access multiple types of log files and pipe in information for it to make since. It has a deeper UNIX/LINUX functionality here. After NP this is the first thing I will be doing is going after my JNCIA as there is such a large presense of Juniper on my company's network.
