I work in IT consulting, we have some clients that use juniper, somicwall, and cisco. We had a person that set up a mpls and VPN network with juniper routers that is no long with us. I am trying to learn off what he setup with the juniper routers. What would be start point to learning routing that will help learn these three but still help me setup and troubleshoot juniper equipment?

Did you look into the certifications that each of these vendors provide?

Juniper: http://www.juniper.net/es/es/training/certification/certification-tracks/

Cisco: http://www.cisco.com/web/learning/le3/learning_career_certifications_and_learning_paths_home.html

Sonicwall: http://www.sonicwall.com/us/support/Certification.html

Unfortunately there's no one fix for learning all of the features of the above.
However, you stated that you need an introduction to routing? If you need networking knowledge, Network+ may be a start. Routing is also covered in Cisco's R&S CCENT.

If you're troubleshooting production equipment - it's best that if you don't know what you're doing; leave it to an external consultant for the time. Look into getting the books and study material available. Furthermore, if management or personal finances can support it - consider going through the certification programs.

I'll leave the rest for the gawds on the forum.

You could take the CCENT, which would give you the basics of routing and switching. If you wanted more, you could go for the CCNA. From what I hear, JunOS is very similar to Cisco's IOS. The routing and switching basics are exactly the same for any vendor (aside from proprietary protocols).

As you have access to Juniper hardware, you may want to go that route if you have access to something that isn't in a production network (old router, switch). Don't go screwing with the company equipment that is being used! :) As far as an emulator like GNS3, I'm not sure if one exists for JunOS.

Buy a certification book for either Cisco or Juniper and go to town. They cover the basics and are actually pretty difficult.

If you know IOS, look into Junos as a Second Language. Great (free) learning tool.

Junos is quite different than IOS.
