Book list

From time to time I get asked about reading lists and books related to CCIE R&S. It is time I’ll place the list online, so with no farther delays and in the order of importance:

  1. Routing TCP/IP, Volume 1 (2nd Edition) - By far, the most important book you must read. First skim through it. Then re-read it. Yes, RE-READ-IT. But now, make sure you understand every paragraph. The only exception are the state machine diagrams.
  2. Routing TCP/IP, Volume II - No surprise here... The EGP section can be skimmed through.
  3. Developing IP Multicast Networks, Volume I - The one and only good book about multicast. You can skim through DVMRP
  4. Optimal Routing Design - Consolidate your IGP/BGP knowledge.
  5. Troubleshooting IP Routing Protocols - You know what i think about troubleshooting...
  6. QoS for IP/MPLS Networks - Just read the QOS part. The best QOS book out there!
  7. Cisco LAN Switching - Very dated, but most of it still true!
  8. MPLS and VPN Architectures - It sounds dated, but nothing has changed. Understand this, and you are the king of MPLS for the RS lab.
  9. Configuration Guide - Both for 3560 and IOS 12.4T. For each topic, before doing a technology lab, read the relevant chapter(s) from the configuration guide.

That is it.

And remember, if you are using Private VLANs or plan to, make sure you visit my Private VLAN appliance site. You do not want to miss it.


The marathon was really a hard one. 800 meters of total accent (2600ft). But, it was worth it! What a great scenery, it was more a tour then a marathon ;)

Now back to R&S/CCIE stuff. I’ll am working on some new entries to the blog. Stay tuned!

3 weeks to go

I know it is a little slow here in this blog. There is a reason! I am busy. The marathon is 3 weeks from now, so in the past few months I was very busy training.

I have lots of ideas for new mini labs and some other stuff. Stay tuned...

Happy new year!

I wish you all happy new year.

Lately I was busy authoring R&S MOC labs, so I didn’t have time to post here. I am about to finish. Stay tuned for more TS mini labs.

CCIE Flyer and the TS workbook

My beloved CCIE troubleshooting workbook was mentioned on the very interesting interview with Narbik on the CCIE Flyer. Read it here.


Just finished our Troubleshooting labs, I partnered with a VERY GOOD FRIEND OF MINE CALLED Dan Shechter, what a gentleman, a Triple CCIE with unbelievable amount of knowledge. Together we wrote 10 Trouble Shooting Mock labs. We thought that each lab was going to take 5.5 hours to complete but they will take 8 hours each. But man O man, these labs are really GR8. They cover all aspect of CCIE R&S, and ALSO the NEW, YES the NEW “CCIE 2.0 Protocol specific Mock labs” hahahaha, these labs are really tough, I should put a warning and a disclaimer on the bottom of each page, guaranteed to frustrate the best of us.


I have been working on a new project, so the blog was a little delayed.

I have tons of trouble shooting cases/tickets to share with you, so stay tuned.

I’ll publish the next Ticket on Monday. It will be a BGP case/ticket.

dynamips files for the demo lab

The free demo lab, which can be downloaded here, is a huge success.

Many ask me to send them the dynamips version of the initial configurations and .net file.

Since dynamips do not support switches, please skip the L2 tickets, which is ticket #1 on the demo lab.

Please follow the instructions found here about how to use the lab file.

Lab file

Demo lab is ready!

Finally, the troubleshooting workbook demo lab is out!

I am so happy to see that finally, the demo lab is released. You can find it here. I hope sure you will enjoy it.

Please contact me,, for initial configurations for dynamips and other topologies.

Tomorrow I’ll publish a new Ticket, here on this blog. You will have fun with it....
