  1. Indeed, good luck Diego. I’m just starting my Cisco journey. Soon to finish a Bachelor’s in IT, fascinated with Networking, and studying for my CCNA hoping to one day reach CCIE Security. I’ll be checking in to see how it all goes for you.

  2. Hi Diego,

    I read some of your blog posts and I liked them very much, especially the ospf interview question 🙂

    Nevertheless, I saw that your LAB is scheduled for this month and I wish you the best.


    CCIE aspirant.
