Kids shows today…

On May 31, 2011, in CCIE, by Darren

Anyone ever SchoolHouse Rock! back in the 70′s? Just watched the pilot episode and it’s a real shame they don’t make this kind of animation still these days.

The song itself seems to have been used for a number of TV channels worldwide.

I’ve tried to find a DVD of the series for my niece, but can only seem to source one from South Korea :(

Further updates

On May 26, 2011, in CCIE, by Darren

Work has been crazy busy recently…

Thankfully we are coming up to a 3 day weekend here in the UK. I plan to start hitting Vol2 of the INE program. This means I’ll finally start will full labs. The first one will probably be a bit rocky as the first one always is.

We’ll see how this plays out…

Study update

On May 8, 2011, in CCIE, by Darren

I’ve been matching my studying to this post: http://blog.ine.com/2010/10/09/how-to-pass-the-ccie-rs-with-ines-4-0-training-program/

I’ve already done most of what is required. I’ve just finished up to lab 9.9 (IPv6)

Some things have been simply too easy. Other things I’ve needed to check on. I’ve also seen where my weaknesses lie so far (IPv6, Frame-Relay) – I’ve yet to even do multicast, so I’m expecting trouble there as it’s not a favourite subject of mine.

I have been taking notes along the way. There is definitely some more reading I need to do on the weak subjects. I already expect this so nothing out of the ordinary.

I want to finish off Vol1 in the next few weeks and move up to Vol2 – the full labs.

So far, so good!

Final prep for my home lab

On May 7, 2011, in CCIE, Dynamips, Linux, by Darren

So now that I’ve got all the real equipment, it’s time to deploy everything.

As noted before, this is the way that I’ll be working: http://mellowd.co.uk/ccie/?p=1516

This is currently how the physical stuff actually looks like:

P1010984 Final prep for my home lab
P1010985 Final prep for my home lab

Now there were a couple of things I noticed when trying to get InternetworkExpert’s topologies onto my lab. Firstly I need to hard-code both my emulated routers and my real switches ethernet interfaces to 100Mb/full. Some of the interface names have also changed (s0/1/0 becomes s0/1, ethernet becomes fastethernet, etc) – Having to go through all the configs and doing it manually would take forever. Thankfully Daniel (http://lostintransit.se/) created a script to modify his startup configs. I’ve taken that script and modified it a bit more to come up with the following script:

#!/bin/sh
# Shell script to convert INE vol1 configs to Dynamips format
# Changes interface names
# Created by Daniel Dib @ http://http://lostintransit.se/
# Modified by Darren @ http://mellowd.co.uk/ccie

#Check if configs exist
for config in r1 r2 r3 r4 r5 r6 sw1 sw2 sw3 sw4
do
  if [ ! -r "$config.txt" ]; then
    doerror "Configuration file $config.txt does not exist"
  fi
done

The BB1, BB2 and BB3 routers also need to be changed, but as the config never changes in any of the labs you can just download the fixed versions of all 3 from here:

I also need a script on my dynamips box that will up all the interfaces on the NICs and then run dynamips. This is my start script:

#!/bin/bash
#Bring interfaces up
ifconfig eth1 up
ifconfig eth2 up
ifconfig eth3 up
ifconfig eth4 up
ifconfig eth5 up
ifconfig eth6 up
ifconfig eth7 up
ifconfig eth8 up
ifconfig eth9 up
ifconfig eth10 up
ifconfig eth11 up
ifconfig eth12 up

#Start Hypervisor
dynamips -H 7200 &
