Im watching some free vLectures from IPexpert here, the one im watching is the one about Spanning-Tree. Its pretty good so far. I do hope however, that their video-on-demand products are alot better quality. Im still waiting to take the plunge and buy their BLS (Blended Learning Solution) until I know where I stand both financially and knowledge wise (written).

So im finishing up some troubleshooting exercises in Routing TCP/IP. They are mainly about the metrics used by EIGPR. Here’s a review of the functionality of EIGRP and how it chooses the best path to a destination. First of, EIGRP is an Enhancement of the proprietary IGRP protocol, which is almost but phased out by now.

At the bottom of this post is a link to a small article by Jared over at IPexpert about the books he recommends for the CCIE written exam. Anyone who looked at the recommended book list from Cisco is blown away.

So im reading about EIGRP’s DUAL algorithm, and how it works, and MAN, its confusing. After the example in Routing TCP/IP, even they mention it might require several readings. Basically it boils down to the fact if a router being notified of a bad link has a feasible successor or not.

I wanted to post a link to a great site which I have started using called flashcarddb.com, what it does is pretty simple, but it does its job in a slick fashion. There is a system called the leitner system, which in all its simplicity is making you remember things by repeating them in periods with different intervals.

Im having some “fun” with static routes. Its an okay topology, 4 routers connected. The task asked for having some floating static routes, along with some load-balancing routes. Since they are CEF based, it will be load-shared by default to destination load sharing.

So like many others finishing their CCNP’s, ive been looking at the CCIE R&S track. There are two obstacles to become one of the prestigious ones with CCIE digits. One is the written exam, and the second is the lab exam.

As reported on cciepursuit, cisco has announced changes to both the lab and written parts of the CCIE certification. On the written, the normal “style” of cisco exams will take place, where you cant go back and forth between questions, and no review.
