10G Ethernet - The aggregation problem

Hey *, Keith here.  Long time no type.  Anyway I’ve been meaning to write this up here since it’s good information to have, and with Ethan’s post regarding 10G ethernet this seems like the perfect time to get off my duff and do so.
Working at MySpace means tons of high-speed links everywhere.  Typically we’ll have [...]

Building a 10G Network - Part 1

One of my current projects is to build out a 10G network to support server consolidation we’re doing. How did this come about? Well, for a long time, we were corporately going the route of isolating specific services to specific servers, growing these little pizza box 1U servers everywhere. All of a [...]

A workbook Blueprint

So now and then I see the question popping up about which R&S Lab workbook is the best.  I will ask a different question: Is there a way to objectively measure an R&S Lab workbook? 
You have probably read this again and again; it is all about the technologies! So, one of the most important workbook would [...]

Post-Traumatic Test Disorder

To the uninitiated, the CCIE lab exam might seem like any other test.  Oh, sure…it’s harder, there’s a lot to it compared to the average test.  You have to study a long time and all that, but in the end, it’s just a test, right?  That’s what people who haven’t been there seem to think.  [...]

EIGRP Stub Leak Maps - Tutorial

While reviewing IEWB VOL 1 VER 5 labs, I discovered a new feature: EIGRP Stub with Leak Map. I spent some time researching the topic and found out a variation of the feature which is not explored in the workbook.
Here I’ll try to demonstrate EIGRP stub routing with leak map as well as what [...]

IEWB VOL 1 VER 5, Early Impressions

A lot of people work differently, and when it comes to preparing for CCIE lab everyone has a different strategy.
Me, I am more of a reader than a handyman :) that is to say, I spend most of the time reading and far less time labbing. Even in the time I lab, I spend most of [...]

The CCIE Training Business

It’s interesting to watch the CCIE training business these days.  InternetworkExpert adds Scott Morris to their roster.  IPExpert gets together with Narbik Kocharians for some sort of mutually beneficial arrangement.  InternetworkExpert has added a new CCIE community site, because apparently we needed Yet Another Forum.  Of course, Cisco has started their own “learning community” targeted [...]

Unicast Reverse Path Forwarding-Tutorial

Unicast Reverse Path Forwarding is a small security feature

When configured on an interface, the router checks the incoming packet’s source address with its routing table. If the incoming packet’s source is reachable via the same interface it was received, the packet is allowed. URPF provides protection again spoofed packets with unverifiable source.
Though basically a single [...]

Fall Back Bridging Tutorial

Bridging is an obscure topic in CCIE R&S study.
It can be divided in three types
1) IRB (Integrated Routing and Bridging)
2) CRB (Concurrent Routing and Bridging
3) Fall back bridging
IRB is discussed in Lab 3 of internetworkExpert labs.
Basically IRB and CRB are generally used on routers to bridging different VLAN domains. If IRB is used, we can [...]

Old Domain “ethanbanks.net” is Going Away

The old domain name for this blog was “ethanbanks.net”, and lots of folks still link to that.  I will be killing that domain name in the next several hours.  E-mail to that domain will still work, but HTTP requests will not.  That means that you should update your links, blogrolls, and bookmarks to cciecandidate.com instead [...]
