How long did it take you to feel comfortable doing configs?

Hi guys,

I’ve been doing basic networking for about a year now, and I still don’t feel like I’ve fully grasped a lot of the in depth things. I’ve been trying to tackle my CCNA since I began this path, and there’s just so much detail. I understand the concepts and principles but after speaking with a few engineers, I just don’t understand how people reach such a high level of comprehension. For example, I understand how to configure OSPF, but when it comes to understanding the different types of LSA’s and what they do, I just can’t seem to understand it.

So, how long did it take you to reach your level of understanding?

Thanks everyone
