Like many other people who live in houses, I have a contract with a pest control company. Now and then, someone arrives at my door wearing a crisp uniform and carrying a giant canister full of some kind of magical chemical concoction. This pest controller uses a long wand that is attached to the canister to conjure up a magic invisible shield that prevents six- or eight- or hundred-legged creatures from invading my space. I know the pest control service is working and worth it when I am not confronted by any tiny crawling, flying, or undulating critters. Thus the debugger who visits my house every now and again does so because I don’t want to see any evidence of bugs in my living space.

You’re studying your Cisco technologies, preparing to run the gauntlet of certification exams that stand between you and certification. You’re feeling pretty confident in your understanding of the requisite technologies and how they work. You’re particularly confident in your grasp of Cisco’s Enhanced Interior Gateway Routing Protocol (EIGRP), but then somebody mentions something called EIGRP named mode configuration, or possibly even Named EIGRP, and suddenly you’re all like ZOINKS!?!?

In our video series entitled Subnetting Demystified, I have attempted to create a learning resource that provides a good overview of Internet Protocol version 4 (IPv4), focusing on topics that are important to those of you who are preparing for certification exams. In the first few video presentations, we discuss some historical aspects of IPv4 and compare that to where we are today.

Now that you know what an IP version 6 (IPv6) address is, how to identify the types of IPv6 addresses, and how to subnet a block of IPv6 addresses, it’s finally time to configure IPv6 on a network. Perhaps your boss has finally shown some interest and asked you what that whole World IPv6 Launch anniversary you mentioned was all about. Perhaps you’ve simply decided that it’s time to put into practice the topics you’ve been studying in pursuit of your certification. However it happened, you’re ready to implement IPv6 on your network.

Previously, in Parts 1 and 2 of the blog series about Encrypting File System (EFS), we introduced the main concepts and described how EFS encrypts and decrypts files, how you can share those files with your trusted colleagues, and how a data recovery agent (DRA) can recover your files if something happens to you or to your private key. In this final installment of the series about EFS, we’ll look at several typical scenarios.

As a sensible person, you probably wouldn’t run a 5K, even for charitable purposes, without first performing some type of physical conditioning to ensure that you’ll actually cross that finish line. Whether you’re a professional who just needs to warm up and appropriately hydrate before the race or a newbie who gets out of breath just walking to your car, you’ll most likely prepare yourself with the right equipment and an adequate amount of training before you take on that public run.
