EIGRP Narbik Advance Tech.

 

Ok so this is my interpretation of EIGRP ADVANCE TECH LAB, Infact I have re-written the tasks description down in my own words. I found this approach to be the best, as during the lab we have apple of paper and coloured pencils/pens to work with.

Hola!! Still ticking and very much alive. :)

Hola!!

Yep, I have not been blogging at all since months now. So yes I have fallen yet again, but only from blogging and thankfully not from the CCIE prep train. 

About my progress, well I no longer have been maintain'g those progress calenders..so wont be able to post beautiful colorful "My day wise progress.." posts. However I can very well sum it for you. In brief I can say that yes I am kinda done doing all the topics from the blueprint(kinda almost all) atleast once. Phew, getting my prep done was quite a challenging task..during this period I have only covered conceptual advance technology labs. As per me they are the fundamental building blocks for CCIE prep. One thing I have realized is that its virtually impossible for me to cover multivendor workbooks. Hence from here on, I have decided to curb a few and stick with Narbik & INE WB only(as I feel they are more than enough, and not because IPEXPERT products are bad or something of that kind). During this prep time, I have figured out my core weakness areas(more on that latter)..which I will be emphasizing more on now during the second prep sessions.

IPEXPERT CCIE WB
NARBIK SOUP TO NUTS
NARBIK GAP FROM CCIE TO CCNP
NARBIK ADVANCE TECH
INE TECHNOLOGY LABS (VOL 1)

Also countdown has begun, I have around 60 days to re-certify my CCNP. Infact I have been a CCNP since 2007, and as the sun sets on 2013 my CCNP will also lapse(30/12/2013). So to re-certify myself, I will be taking the CCIE written this time around. People either take CCIE written to mark the begining of their lab prep or they do it midway when they are ready to take/book a lab date ie. for me its going to be different.. I am finally committed on pursuing the LAB on my own, never been so clear about it ever(earlier on I was waiting for my employer to sponsor my lab attempt and or get me some sought of a bootcamp enrollment, unfortunately I dont think its gonna happen..& I aint waiting anymore).

So yes, with the amount of workex and hours/years spent in the name of labprep..its clear I will be taking the selfstudy approach. Yes I know its not the best, but that's the only option I have..it worked for my CCNP back then, so aint doubting it this time. Intially I was very worried about it, especially about the lab aspect..yes we all use/rely on GNS3 but unfortunately its never worked for me. I have spent more money and effort either upgrading my workstations or troubleshooting GNS3 issues. Thankfully, during these past 6 months..its changed to something good..something really good..PHYSICAL GEAR!! :D

Yep indeed privileged to have PHYSICAL LAB to workwith(will post more about it latter)

Ciao,
Andy.

Tickle (Tcl) your NLRI !!! :)


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

foreach ip {
 x.x.x.x
 x.x.x.x
 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.

tclsh

foreach ip {

 2000:1:1:12::1
 2000:1:1:1::1
 2000:11:11:11::11
 2000:1:1:23::2
 2000:1:1:12::2
 2000:2:2:2::2
 2000:22:22:22::22
 2000:1:1:34::3
 2000:1:1:23::3
 2000:3:3:3::3
 2000:33:33:33::33
 2000:1:1:34::4
 2000:4:4:4::4
 2000:44:44:44::44} {ping $ip rep 10}

 tclquit

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 
  • SWITCHING



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!! :) 

Greets!

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 ..as 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

And ya, all credits for the work go to Jeremy Stretch. If you want a pdf version of it you can get one from his site.

New highlights for v4!

Ok, this is where Scott Morris posted his views on the new blueprint, whats important are the new topics that are now in v4,

In brief, below are the highlights for same:
PPP over Ethernet (PPPoE)
• Performance Routing (Cisco PfR)
• Optimized Edge Routing (Cisco OER)
EIGRPv6
MPLS Label Switching
MPLS Layer3 VPN
MPLS VRF-Lite
Interdomain Multicast Routing
IPv6 Multicast support
Multiprotocol BGP (MBGP)
• Zone-Based Firewall
• Control Plane Policing (CoPP)
• Intrusion Prevention (IPS)
• Gateway Load Balancing Protocol (GLBP)
AutoQoS
• Embedded Event Manager (EEM)
• Concept of “Optimize the Network”


If you first look at them, you might get heartburns! ;) But latter one should find peace with it.
One more important comments that I saw from M/s Laura O (an official from Cisco) is,"From a Cisco program perspective, I just want to add that one way we've made room for all the new material, is to preconfigure some of the basic routing and switching in the Configuration section of the lab. This aligns well with what actual network experts encounter--the basics are performed by others, so they can concentrate on the more advanced configuration or problem resolution tasks."
:D

So gone are the days, where we candidates were suppose to not only wire the rack but we no longer might need to type, router ospf 1 follow it up by the network 0.0.0.0 0.0.0.0 area 0 command. ;)
Or in other terms, I think v4 is as close as possible to the real world ..hey, after all CCIE is meant for real experts ..init?!

Dynamips Tutorial

Ok, this is a brief tutorial of how to use dynamips for your ccie lab prepration. This tutorial was originally created by folks at internetworkexpert.com and is freely available for all. Thought I would post it here. :)

Btw, I'm speechless when it comes to dynamips, simply funtabulous work of art!!

Part 1 of 3:



Part 2 of 3:



Part 3 of 3:




Enjoy!

The original " why blog? " post.

I am using this as a means to track how my studies are going, I know pretty selffish of me. Perhaps! I think using the art of blogging I can sought of keep it going at all times and this place will serve as a good archive for me to look up any info on a specific topic that I stumbled upon, thereby serving as a ready reckoner.

Its very fresh so bare with me, as I was not all that keen at first and thought blogging will actually take some time away from me. As you know that time is scarse when you have a full-time job and ccie studies to manage. But what the heck lets give it a try ..

Feel free to comment… I like it when you do because it makes me feel like someone is actually listening and I am not just typing this to myself. :)

Btw, I will be doing the Routing and Switching track!!

Greets!
