Study Materials: MPLS

Well, as predicted I made it about 300 pages into the End-to-End QoS book before needing a new topic. As I had a large chunk of time to spend last week I decided to bear down on MPLS; a technology I was less familiar with and really needed to clarify my understanding of. To that end I worked to finish Definitive MPLS Network Designs and also make headway in MPLS Fundamentals. Definitive MPLS has really excellent explanations but its density was too great for my rate of absorption last time I tried to read through it. By getting a better grasp on the fundamentals via some CiscoLive video sessions I… Read More

Book Complete: IP Multicast, Volume I

As promised I finished it, IP Multicast, Volume I. I enjoyed the book and it certainly improved my understanding of multicast. I was struggling at the end to make it through the chapters on IPv6 and Troubleshooting but I do notice I get subject fatigue after so many pages (generally around 300 or so). I’ve nearly updated all the mind-map bits and will get a fully updated version posted soon. Next, as I mentioned, is End-to-End QoS Design. I’ll be honest in saying I’m not looking forward to a 1000+ pages on QoS so I might have to break it up and do some other reading between. We’ll see soon… Read More

Book Complete: Optimal Routing Design

Well, I broke from my plan in finishing IP Multicast, Volume I and completed Optimal Routing Design (or ORD as I’m using in my internal notes) first. I am almost complete with the Multicast book as well – just a bit more on the IPv6 portion but I needed a break from pure multicast and got sucked into ORD and finished it. It is a great read and very, very easy to consume I think. It does a great job of laying out each major protocol and specific concerns around them along with use-cases and examples to illustrate. As most of the text revolves around networking protocols you’ll see updates on… Read More

Certification News: Passed f5-201

Long Journey, Much Delay I started this journey over two years ago. When I joined my current company I decided I would get f5 certified as I didn’t think we had folks with it and I could help expand our business by being “that guy”. The reality is that we didn’t have a lot of f5 work and I had other things to master ahead of it. I went to Agility 2016, took the 201 training course and determined to get through it then. I didn’t. The next year I signed up for the 301a training and thought I’d complete both 101 and 201 in prep for Agility 2017. Again,… Read More

CCDE Practical Take #1, May 30th, 2018

Reasoning for the Post It seems customary to write one of these posts after attempting a CCIE or CCDE. At first, I resisted as I didn’t see much value in reporting my experience out – at least not over what others have already written and can be found with a Google search (which is far more likely to return a result than this posting). Nonetheless while attending the excellent session LTRCCDE-3006 at CiscoLive this year I was proven wrong. I took the session for the second time; my first was last year when my CCDE preparations first started in earnest. It was very good I thought and helped give me… Read More

Book Complete: QoS for IP/MPLS Networks

I finally finished a study book in its entirety – QoS for IP/MPLS Networks. I’ve been bouncing between different texts, depending on what mood and topic struck my interest. I’d also been reading on many topics I am already familiar with to try and bolster and deepen my understanding and draw connections between things. I’ve decided to pause this idea and instead focus in on a major area/concept and read all the way through to completion. I get “credit” when I’ve completed reading the book, augmenting any necessary mind-maps with the information from it and then generating the Studies flash cards as well. I enjoyed this one. Study books are… Read More

Resilient Ethernet Protocol (REP)

REP was a protocol I wasn’t familiar with prior to reading on industrial networks and working with manufacturing customers. I never dug too deeply into the features of it however till I began my studies. This is one of the first mind-maps I completed in my CCDE preparations. I hope it is of some help. Due to file limitations by the hoster I’m working out a method to provide access to the iThoughts files (and other mind-mapping formats). More on that soon.
