Juniper to IOS conversion chart

Moving to JunOS from IOS can be a daunting task. It’s a completely different command structure and the config, by default, looks like a programming language. I was fortunate enough to have gotten in on using JunOS very early in my career, ¹⁄₃ in to be exact (as of this writing). Not to mention that wen I got started, IOS wasn’t the only game in town. Remember Xylan? Gandalf? OpenRoute? How about Ascend?

That being said, a conversion chart is a useful thing.

These are everywhere on the net. Recently I was asked to provide some of this for my job, so I took most of what I could find on the net and compiled it together using my favorite one as a template adding this and that from my own bag of what I thought was useful, which was very little since the initial one was pretty complete. I suspect this may migrate to a “page” and not just a post, and will likely be a bit of a living document as I find more and more useful bits and pieces.
