IS-IS is very confusing..
Well, at least some of it. Adjacencies and how IS’s update other IS’s is the thing that nobody can give me an answer to. According to all the material IS’s maintain adjacencies to all others, but still elect a DIS.
(3) EIGRP – Labs
So yesterday, I started with all the lab exercises that has to do with EIGRP. I did the one in the self-study guide, and one (2.7.1) in the lab portfolio. I also started on 2.7.2.
So far, the labs in the labportfolio are far better written than the ones in the self-study guide.
(3) EIGRP – Note taking
Alright, I am done with reading about EIGRP. I am now skimming through the chapter, and taking notes. I have an okay understanding of how EIGRP works, and I am looking forward to the labs to nail out unknowns.
I am not 100% convinced about taking notes, or rather doing it in the order im doing (reading first, then skimming and taking notes, then going to the lab).
(3) EIGRP reading – continued
Today, I am continuing reading about EIGRP.
My goal for today is to get at least 40 pages of EIGRP reading done. Lots of nitty gritty details such as unequal-load balancing and route authentication.
To understand and process the material, 10 pages takes up 30 minutes of reading time.
(3) EIGRP Reading
Chapter 3, EIGRP.
Started reading about the inner workings of EIGRP today. EIGRP is an improved distance vector protocol provided by Cisco themselves. It is an improved distance vector protocol, because it passes updates directly to its neighbours. It is more advanced than traditional distance vector protocols, because it supports VLSM and it does not use periodic updates.
(2) Routing principles – BSCI selfstudy
Okay. I will try and document some information regarding my study to attain the BSCI (Building Scalable Cisco Internetworks) exam.
This is by many considered the hardest exam on the CCNP track (1 of 4 exams). I will tackle this one first, and then continue forward to the other exams knowing they will be easier.
