CCNA Routing Protocol Comparison Chart Revised
Routing Protocols Comparison for CCNA I have always said I was going to make this chart since I draw it on the board for nearly every CCNA class I teach. Well, here it is. I may add to it later. Name Class Type Administrative Distance Metric Classful/less Algorithm Transport Type

CCNA Routing Protocol Comparison Chart
I have had many classes where students have asked me for a simple chart that I write on the whiteboard when covering the routing protocols. I finally put it to paper and am providing it here. I hope some of you find it useful. Name Class Type Administrative Distance Metric Classful/less Algorithm RIP v1 Distance Vector IGP 120 Hop

IPv6- Is it more Secure than IPv4
In my IPv6 Class this week we get to touch a number of IPv6 topics. We have already discussed the Basics of IPv6, Routing Protocols, and QoS features. Aside from tunneling, which we cover on Thursday, one of the topics that I am most facinated with (being a CCIE Security) is of course….wait for it……Security! As I prep ahead of time for my class I can’t help but look to see what new and exciting resources are out there to share when it comes to Security. The following video, IMHO, is pretty darn cool. Take a little time to watch it and let me know what your thoughts are. Related posts:

GNS3 setup and outside connections with VoIP example
I don’t want to write another guide to setup GNS3, there is a great tutorial which (in my opinion) covers all necessary steps. I just want to summarize a few things which may shorten the time to get a router in GNS3 to run, make it talk via the ethernet of your PC and connect to a physical router. Further I added an example for some simple VoIP configs to make a CME (with an 79xx phone registered) in the virtual router talk to a FXS interface (analog phone) on another router. First of all you need to install GNS3, which in turn takes the necessary steps to install the underlying dynamips. Special thanks for this excellent work goes to the folks around the dynamips and GNS3

Is Core Knowledge Key?
In some popular online forums people have been talking about how the number of candidates that have passed the CCIE Security since the new version is very low, almost non-existant. While there may be issues with the lab itself, a claim on commenter made, I wonder how much of this is related to a lack in understanding of core knowledge concepts. See, as an instructor its easy to get into the trap of knowing all the technical details of how something works because you teach it so often and yet you lack in practical configurations. This is something I have always fought against, one reason I spend as much time as I can on the equipment. But when it comes to the CCIE you have to
