Patent filed

Finally, I have finished to file my patent regrading PVTD - The Private VLAN enabler. It is storage how a patent attorney is able to add so many words to a technical document which he has got very limited understanding of its content… Anyway, I am back to authoring labs.

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. ...And remember, if you are using Private VLANs or plan to, make sure you visit my Private VLAN appliance site.

Marathon Networks’ PVTD

I have seen many broken Private VLAN networks, and decided to find a way to fix them. So in the last year I have developed a network appliance called PVTD, which solves many of the Private VLAN problems. You can read all bout it at www.marathon-networks.com

L2 is now in the TS section

L2 is now in the TS section of the R&S lab: https://learningnetwork.cisco.com/docs/DOC-10859 ...L2 is in the TS workbook from day one because the TS workbook was written not just to prepare the students for the TS section of the lab, but also to summarize, test and sharpen the skills of the CCIE R&S students. Please notice that although the TS section is the first section of the lab, I recommend to practice the TS section after doing technology focused labs and moc labs.
