Tickle (Tcl) your NLRI !!! :)

You can use a simple Tcl script to test connectivity between your devices:

foreach ip {
 x.x.x.x} { ping $ip

For example, below is one tcl script that I had ready to check NLRI after performing an OSPFv3 lab.


foreach ip {

 2000:44:44:44::44} {ping $ip rep 10}


There is an obvious advantage when using these kind of scripts, that is you end up saving lot of time during practise and this is also a must use tool  during ccie lab as well; especially when you want to check your basic network reachability before you break for lunch.

Day Wise Progress for AUGUST!!

This time, I have got a slightly different approach towards my lab studies. Instead of starting my preparation with easy topics.. will be doing it in reverse.

Which mean difficult topics need to be tackled first(from experience I can tell you its always going to be advantageous to score the difficult ones first).

  • BGP 
  • IPV6
  • QOS 

I plan to do the above listed topics from  the below vendor workbooks, Narbik Advance Tech WB, Narbik STN WB, Narbik GAP WB, INE Vol1 v5 and INE Vol1 v4.5 which sums to be around 100 odd labs just for BGP. 

I am pretty well versed with the theory aspect of BGP, infact I have also nailed Cisco BGP 642-661 certification 2 years back. So I simply need to review and lab it up again. Below is my day wise progress
Will keep this chart updated.. as I go through it!! :)

Trying to crawl back to the prep train!

Yeh, had been busy with work off late. But here I am with new list of to-do topics, if you have been following this blog then yes I was in hibernation all this while from the time I took a new job.. and then also went ahead and got married!! :)

Anyways, the job and married life seems to be kewl ..with any new role it takes some time for anyone of us to adjust and understand one's role in the organisation. So off-late I seem to have reached the comfort level and hence have decided to get back to my CCIE prep.

Also, back then when I started preparing I was mainly dependent on GNS3/Dynamips for my rack access(we all know that working with emulators is not for the faint hearted). Point being I did end up wasting a lot of time fixing emulator problems. I have been lucky enough to now have my own rack access pod setup(more on that coming up).. but now with this more dedicated approach, I should be better prepared to nail the beast.

I intend to work towards the goal for at least 3-4 hours on daily basis and tackle the lab topics on tech based approach. I know, it will be like starting fresh ATM if I think right of the bat then I can hardly remember the minute little details that I had worked on so hard.

So with a hope that things will come back to me gradually as I move up the path you will now see me blog more often here, if not daily. See you along.. :)

BGP Cheatsheet!!

While I was doing some casual surfing, this is what I found. It made me remind of the texbuddy charts that I use to use for my CCNA prep/quick revision. Well inspite of it being of very basic nature, I still thought its a good one.

Wouldn't we all love one for all the technologies including all the details about them at the CCIE level, I mean a one stop chart. Makes me wonder what that chart would be like!? Perhaps, its time for those CCIE course prep vendors to come up with. :P
