Status Update

On July 31, 2011, in CCIE, by Darren

I’m currently following INE’s recommended training program over here: http://blog.ine.com/2010/10/09/how-to-pass-the-ccie-rs-with-ines-4-0-training-program/

Currently I am on week 12: VOL3 Labs 1+2

My week starts on a Sunday as it’s the easiest way for me to work out the labs for the coming week and so. It also gives me a lot of time on my first day of that week as I have to actually work the rest of the week of course.

Vol3 lab3 was super easy. These labs are pretty much core technologies only, and they are designed to speed you up. You have a total of 3 hours per lab. I finished lab1 in 2 hours and 3 minutes and I got 95% of the tasks right. That gives me great pleasure :)

I’m going to start up lab2 now and see how it goes.

Between the actual program itself, I do watch INE’s Advanced Technologies Class on Demand as well as continuing to read through the CCIE reading list and various other blogs.

 

CCIE Redistribution labs – #1

On July 27, 2011, in CCIE, by Darren

I used to think I was pretty good at redistribution between routing protocols. However the more I do the labs from INE’s Vol2 workbook the more I realise how complicated it can actually get.

I’m used to working on networks with either a single IGP and BGP, or at least a well though-out network with multiple protocols. The labs in INE’s workbook, as well as the CCIE lab, are going to make this as difficult as possible to ensure you actually know what the heck is going on.

So I thought to create a bunch of labs focused solely on redistribution. The end goal will simply be that all routers have full connectivity to all routes via their loopbacks. No static routing, default-network, or default routing allowed. You are also not allowed to change any of the IPs

How to quickly figure out all the networks and then get each router to mass ping all addresses from their loopback interfaces? Easy. Check out this post from Daniel.

Generally I shy away from GNS3 and use dynamips directly. But the nice thing about GNS3 is that I can make a lab with a graphical representation quickly to show on the blog. The actual .net files can still be imported into dynagen without a problem.

This is the topology I’ll be using. Note that not all labs will be using all links all the time. In INE’s tradition, Y will be equal to the router number for easy IP addressing.

Topology CCIE Redistribution labs   #1

Note: You’ll need to adjust the initial configs to match your IOS image, location and idle-pc values

Lab1:1 CCIE Redistribution labs   #1
Initial configs: Configs

Lab2:2 CCIE Redistribution labs   #1
Initial configs:Configs

Lab3:3 CCIE Redistribution labs   #1
Initial configs:Configs

EDIT: I forgot to put up the actual .net file itself. Again you’ll need to adjust some variables to match your home set up.

Back from holiday

On July 12, 2011, in Uncategorized, by Darren

So it’s time to hit the books again. I tried to start yesterday, but had a damn problem with my dynamips and I could not fix it yet. Annoying as it was working perfectly when I left!

Expect more posts shortly :)
