Other Ways To Build Knowledge For The Lab


There are some other things I’ve added to my daily routine to help me build knowledge.

  • I’ve subscribed to the Cisco NetPro Lan, Switching and Routing RSS feed. The forum doesn’t see too much traffic, but the issues presented there are the kinds of things that a CCIE candidate should know the answers to, period. For instance, an issue came up today regarding a problem with a PBR route-map not sticking to a 3750 (stackable version of the 3560) SVI. Seems that the issue might be related to the switch SDM template. Really? Huh – cool. I was aware of SDM templates from a standpoint of making a 3560 a dual-stack IPv4 and IPv6 router. But are there other SDM templates I should know about? Apparently there are. So I’m going to read up on it.
  • I am printing and reading the workbooks, Volume 1, version 4.1. IEWB Vol.1 focuses on individual technologies. For example, I read the frame-relay PDF last night. The PDF took every possible frame-relay scenario and explained how ARP, LMI, DLCI assignments, and static mappings all worked together, so that you could clearly understand how a frame was making it from point A to point B, no matter what the topology. The PDF was very well done.  I knew 90% of what was in that PDF already from having hammered on frame-relay via the DOiT labs, but even so, there were some new things that made me smarter about frame. I’m hoping to get through the IEWB Bridging & Switching PDF today – about 150 pages of material. Let me give you a better description of what’s in these workbooks, so you can understand why I’m enthusiastic about them. What IE does in these workbooks is as follows:
    • Describe a specific technical task.
    • Diagram the task.
    • Write out each step in plain English to accomplish the task.
    • Possibly, they’ll give you a list of questions to ask yourself while performing the task.
    • Provide the IOS code to accomplish the task.
    • Show you device output that verifies the task was accomplished.
    • Possibly, they’ll conclude with a plain-spoken paragraph reviewing everything that was just accomplished and why it worked the way it did.
    • Provide a URL so that you can read even more about the topic if you so desire.
  • I’m planning to go through all of the technology overview PDFs, at least for the parts that apply to the R&S lab. I’m going to add to that a review of the available IOS commands for R&S technologies. That should be good exposure to anything that a proctor might throw at me on the lab. I’m thinking about following that up with a series of blog posts called “10 Words Or Less” where I take a group of IOS commands, and in 10 words or less, describe what each command is used for.
  • Of course, I’m still doing practice labs. Practice, practice, practice. But I believe I have to do this other stuff too, to be ready for the lab by my April 29 date.

  • You say you subscribe to the NetPro “Lan, Switching and Routing” feed. If you have not done so already, I would suggest you also have the “Wan, Routing and Switching” feed. It’s the same sort of stuff, but the emphasis is on routers and routing protocols rather than switches.

    I’m surprised you say the forum doesn’t get too much traffic. I use the web digest rather than RSS, and I am seeing 50 or so new topics per day (about 150 postings) in each section, which is about the limit of what I can keep up with and study at the same time.
