Just about an hour ago, Cisco made the CCIE Data Center written exam available to be both scheduled and tested. So stop reading this and go schedule your written exam!     Assuming you are now back from scheduling your written, purchase and begin watching our CCIE Data Center Nexus Switching course to prepare for your lab exam, as those videos are now available for streaming and download (the page still notes they are coming, and we will get that updated today, but be sure they are indeed ready...

Brian Dennis and I attended Cisco Live! - Networkers this week, and both enjoyed the privilege of sitting down to talk privately with Yusuf Bhaiji (Program Manager over the entire CCIE program) and Ben Ng (Program Manager over the CCIE Voice track) for roughly 45 minutes. It was quite an enjoyable and spirited talk, and I believe it benefited both sides - our side to gain a better understanding of why some of the choices have been made, and theirs possibly to see things a bit more 'through the...

Many times, students believe that they could use a bit of a boost when it comes to solving the very complex and difficult Practice Lab Exams featured in our famous Volume II workbook here at INE. To respond to this, Keith Barker and I came up with an idea for a new INE product unlike anything that had been created before. We created a fully interactive video guide to lab exam strategy and actual solutions for the first five labs of the workbook. But we did not stop there. We also recorded bonus... Read More

One of the most important technical protocols on the planet is Open Shortest Path First (OSPF). This highly tunable and very scalable Interior Gateway Protocol (IGP) was designed as the replacement technology for the very problematic Routing Information Protocol (RIP). As such, it has become the IGP chosen by many corporate enterprises. OSPF’s design, operation, implementation and maintenance can be extremely complex. The 3-Day INE bootcamp dedicated to this protocol will be the most in-depth... Read More

Continuing my review of titles from Petr’s excellent CCDE reading list for his upcoming LIVE and ONLINE CCDE Bootcamps, here are further notes to keep in mind regarding EIGRP. About the Protocol The algorithm used for this advanced Distance Vector protocol is the Diffusing Update Algorithm. As we discussed at length in this post, the metric is based upon Bandwidth and Delay values. For updates, EIGRP uses Update and Query packets that are sent to a multicast address. Split horizon and DUAL form... Read More
