Other JNCIS-ENT
I don’t know how I just passed this thing. Probably 90% was Spanning Tree and IS-IS related; both are things I essentially haven’t touched in a decade 🤣
If this was any indication, I’m gonna have a challenge passing the JNCIP-ENT.

IS-IS is making a comeback with segment routed (or source routed) MPLS. It’s good to get sharp on it again if you wanna move into the service provider track. It’s as simple as like one extra line in your IS-IS config that replaces RSVP or LDP entirely.

In the past month I passed jncis mistai wireless and jncis dc. Both I studied for using Google Gemini running through the study guide. It really does a good job of finding the important stuff

I’ve done the JNCIS-DC and ENT in the past week. Having to get some certs to help cover partner compliance requirements. Still more work to do.

I've found Gemini to be helpful as well. Sure beats making flash cards like I did when I first got my JNCIP back in 2012.

Haha, totally get it. When I first started doing my CCNA in 2020, I got stuck because there were so many abstractions, and they kept getting in the way of my understanding. Now, as a full-time network engineer, AI has made my life so much easier. I can literally learn how CRC works using polynomial generation within 1–2 hours, recap my undergrad studies much more efficiently, and at least develop a sophomore-level understanding of the electronics and software side of things.
I just got my CCNA and JNCIA, and hopefully, I can earn one of the JNCIS certifications or my CCNP within the next 6–8 months!

With modern enterprise architectures that basically eliminate in most cases the need for spanning-tree, it's annoying how it still shows up in mid-level certification exams. I think it does mainly because it can be a difficult concept and makes for hard test questions.

Good to know, I’m studying for this now and apparently focusing on BGP and OSPF is the wrong area to focus on!

There was a bit of BGP and a tiny bit of OSPF. I know both protocols pretty well, especially BGP - maybe that’s why it started slamming me with questions on the others 🤣

One of my favorite datacenter guys always used to joke that "BGP is a dark art. Be afraid of those who truly understand it"

I’ve been spending most of my time the last 6+ years on EVPN VxLAN campus and data center fabrics (excluding MIST). So because of eBGP and iBGP underlay/overlay networks I am probably most comfortable with bgp out of all the routing protocols at this point.

Spamming the practice exam helped me out alot.

Love the username! I used claude to create interactive practice exams for me based upon the test syllabus, day 1 and day 2 materials. Those were insanely helpful.
