MPLS for Cisco Networks now available!

It's been a long ride. Finally, though, it's finished and being published.

MPLS for Cisco Networks is here!


So what has changed and what's stayed the same?

The format is the same. We have one main topology, it grows and changes as we cover all the topics on both the official CCIE v5 blueprint, and also the INE expanded blueprint. There are smaller, sub-contained, topologies where appropriate. We now have a longer troubleshooting section, with one topology and seven different tickets.

The biggest difference is that we have an editor for this one. Beau emailed me, asking would I like him to edit the second volume (after he read the first one). At first I was a little unsure. The BGP volume was my baby, in a way, and would you let a complete stranger look after your baby? Well, its not like handing over my children, and his credentials looked good (ex-Teacher, Network engineer - so what more could I want!). I do not regret taking the chance and asking him to join me. Together we have created, in my opinion, an excellent book. He's been juggling parenthood, work and being a husband, with hours and hours (and hours) of correcting my grammar, making sentences shorter and more concise. If I gave a penny to my children for every time he's had to add a comma, they'd be rich by now! Seriously, I cannot say enough how he turned the book around. It's far more readable. My sentences do have a tendency to be a little long, it's all to do with how it comes out of my head as I am working through it. So when you are reading it, and you pause for breath in a paragraph, you can thank him! It's not just the grammar though, he's been through the topology with such dedication. It's been excellent to have another pair of eyes on it. He must be a glutton for punishment though, as he's agreed to do number 3 as well!

We have more pictures. This does influence the size (for Kindle), and has meant that printing costs (as well as the fact that its much longer) have increased. It is slightly more expensive than the BGP book, but still very reasonable. I am not out to make a fortune from these, I am doing it because I enjoy it.

We are still using GNS3. It's probably the most familiar to people, but IOU topologies will follow in due course.
In all, I am more pleased with this one than the BGP book. In hind-sight I think I rushed the BGP book. I never expected it to ever be as popular as it has been. When I published on Kindle (not even thinking at that stage it would appear in printed format), I said to my wife that if a couple of people enjoyed it, then it would be worth it. I am still very proud of it, nonetheless. It's a learning process, not just in the material, but in how to write. It will become a more honed process as I write more. I hope I have listened to all of the requests that have come in (apart from one, which, I think, was just asking me to write it exactly like an O'Reilly book - still not sure of that conversation, I was very confused).

I hope you enjoy it.

Sneak peek at volume 2

It is not quite ready yet, it's still being proofed by my technical editor, but I thought I would get a proof copy or two so that I can make sure formatting is right  and that the pictures are coming out properly.

I must say I am pleased so far. So, want a sneak peak?

Here you go!





As you can see it has become a much longer book than the BGP volume! We have many more pictures for a start. 

It's still based around GNS3 and IOU topologies will follow. 

I am very excited by this latest volume. 

Work on volume 3 is already underway. 

Design the next cover, win an Amazon voucher and a free copy of the next book!

Volume 2 is nearly completed, I have ordered the first proof copy so I can check layout, image quality, and how things line up compared to the first one (purely from a layout perspective). Beau, my technical editor, is still going through it, but it should be coming soon.

So, what's next?

Originally I had planned to to the IGPs (RIP, OSPF, EIGRP and IS-IS) next, but instead I have chosen to do "VPNs and NAT for Cisco Networks" for volume 3. In this volume I'll cover GRE, DMVPN, GETVPN and NAT technologies for both IPv4 and IPv6, I think this follows the progression nicer as we have started off with the global view of BGP, the larger scale enterprise with MPLS, and not we can start to look at connecting smaller sites together using VPNs, and with that NAT technologies. I think it'll lead on to the IGPs for volume 4 better this way.

Now I need a new cover design, and this is where you come in.

Have a look at the existing covers:



BGP (in my view) looks like a very interconnected world, highlighting the importance of BGP in our global internet, and MPLS looks like fewer connections, for the company to company networks.

For the next volume I am looking for something similar, abstract, yet understandable within the context of the book. I would like to use the same colors to keep within the running theme, or as this is a steady progression as we move into the IGPs, then maybe green, I like green as well. We don't have to stick with the circular "globe".

So if you want to have a go, then hopefully you can see what I am looking for. I would need this in a Photoshop PSD file of 7.5 x 9.25 (inches), I can handle the text part.

The end date for this will be December 1st.

The winner will receive a copy of the next book, and a £50 Amazon voucher (or equivalent in your local currency, i.e. $80 USD).

What do people use the most for their CCIE studies?

I have been running a poll on the site for a while now, to get a feel for what people are using for the practical part of their CCIE studies. The results are in, and thank you to those who have taken part in the poll.

Here are the results in reverse order, and if you don't want to do the reading then skip to the end where there is a pie chart.

CCIE on VMWare

1% of respondents are using VMWare. VMWare is a great platform, but, historically, not ideally suited to the CCIE. This has started to change somewhat, as the CSR 1000v router works well on it, but, then there is the costs associated with using this platform, if you are running 10 routers then you are going to need 32GB of ram, running 20 you'll need 64GB ram, and this is all on the basis that you have a machine to hand that can run VMWare. Not a surprising result.

CCIE on Real Hardware

8% of you have either a very accommodating employer, or a lot of cash to drop. I did go down this route, and got all the hardware a couple of weeks before the V5 was announced and all my routers (barring the 18xx series) became pretty much obsolete. But there are a number of you lucky enough to have the full hardware based experience! Lucky you, really there is nothing like the real thing.

CCIE on IOU

25% of people are using IOU. IOU is great for many reasons, firstly the version level supported is much closer to the one used in the exam, it's free (yay!), and you can run a large topology inside a VM with very little memory overhead. The downside is that it is harder to get into, those without any Linux experience may be put off, and designing your own topologies does take some getting used to, It works great, but isn't for the faint-hearted.

Real switches + IOU or GNS3 or VMWare

25% have opted to use real switches and a virtualised environment. This setup does make the most sense, as all the virtualised environments have issues when it comes to layer 2 technologies. The switches can be bought (on eBay) for a few hundred (pounds), and as the routing functions work great in virtual environments it eliminates the chances of errors due to a layer 2 feature not being supported, or, if supported, not working as it should (I am looking at you HSRP!). There are some downsides to this setup, mainly the cost, portability and space concerns, but it does offer the best of both worlds.

CCIE on GNS3

36% of people are using GNS3. It has been around for years, and it making huge waves as it progresses from the 0.8 version that we have known and loved for ages to this all-encompassing vital tool, allowing you to run VirtualBox VMs, connect to IOU and to real hardware, if you don't want to do that then it runs 7200 series routers (which support IOS 15) very well. It is of no surprise then, that GNS3 is the tool of choice for the aspiring CCIE. The downsides of GNS3? Not many really, it does have a propensity to make your CPU run hot, but playing around with idle PC values can mitigate that, and you are limited by the amount of memory you have if you are running native GNS3 routers.

Final thoughts

The lines in this poll are slightly blurred though as some may be using real hardware and GNS3, or real hardware and IOU, for instance, which really does push their numbers up, but it does give a good indication as to what people are using.

Whatever platform you choose, I wish you all the very best in your studies.
