1 Minute Management Lesson with Shit !!!!

*Story*

A turkey was chatting with a bull. "I would love to be able to get to the top of that tree," sighed the turkey, "but I haven't got the energy."

"Well, why don't you nibble on some of my droppings?" replied the bull."
They're packed with nutrients."

The turkey pecked at a lump of dung, and found it actually gave him enough strength to reach the lowest branch of the tree. The next day, after eating some more dung, he reached the second branch

Finally after a fourth night, the turkey was proudly perched at the top of the tree. He was promptly spotted by a farmer, who shot him out of the tree.


*Management Lesson*

Bull shit might get you to the top, but it won't keep you there

Into ccie IGP

I am getting into core IGP of my ccie studies. I am into Rip now though its pretty easy the amount of learning i get & the speed of configuration which is key in the lab is going up significantly. I hope to get started with Vol2 labs by May end.

As of now my status with rip is as follows;

RIP:

Routing TCP/IP vol 1 Second edition --- Completed
IE volume 1 ver 4.1 --- Completed

Yet to be done is the IE volume 1 ver 5.0

Lets see how it goes.

Lets Kick some a$$ !!!

Alright , am really in an armorous mood as I blogs this. ?Being a big bag of lazy bones is enough. I really need to put in all my effort to go in for the kill.

Due to some changes in my work place am stooping my exploration in the security section as of now. As far as I have read I have read it well. So I will get into practicing the core IGP before moving in to volume 2 labs.

I am racing against time. Got to put in more effort & kill ccie in my first attempt. Now I am starting off with the all easy RIP :)

Well if Rip can fetch me 5 to 8 points in the ccie lab. I will study it with all respect.

Ok am off now will catch you in 4 hours time.

Bogon Address - What is ...

I was just going through the "Traffic Filtering" section. I came across this interesting attack of using a "Bogon" IP address.

"Bogon" is name for an IP packet on the public Internet that claims to be from an area of the IP address space reserved, but not yet allocated or delegated by the Internet Assigned Numbers Authority (IANA) . The areas of unallocated address space are called "bogon space".

Pretty neat huh ...

The following link from IANA shows the unassigned and unassigned IP4 address space.


So how do we filter it ? stayed tuned ...

Fun with Access Lists !!

I really never expected learning access list would be so much fun. I am actually enjoying the study path :) which is very important !! It was interesting to see the DOC-Cd format change for the security section of the 12.4 version.

Hopefully the entire security section except the catalyst part should be over :) by 26th of this month.

Then we jump into the core part of the game !! Doing volume 2 labs :)

I am very eager to be done with the R&S track, it seems to be taking forever , but it will eventually pay off :)

I will start labbing up more with complex scenarios & will definitely post it in this blog.

Biggest mistake for IPv6

Found this interesting article from network world which says;

The Internet engineering community says its biggest mistake in developing IPv6 - a long-anticipated upgrade to the Internet's main communications protocol - is that it lacks backwards compatibility with the existing Internet Protocol, known as IPv4.

The Security Deal

aaa & security server protocols should be done by tomorrow !! I will be starting with Traffic filtering and firewalls from Tuesday evening.

Security is an interesting topic & probably I should think of taking up my 2nd ccie :) ... lets finish the R&S first.

Realising the Doc-CD magik !

Starting with the security section .. I dint have an materials to read through. While starting my ccie journey I ensure I have reading material for all sections of the blue print except for security. While doing my ccie written & ccnp I had borrowed cisco press books from my colleagues. No I felt a little short handed while preparing for the lab. SO what do I rely on for reading until I get my books ???

aaah the Doc-Cd .. but .. I always either feel drowsy skimming through it.. I thought, ok lets start with it & to my surprise I really enjoyed reading it. Though I realized the value of it for sections I was not familiar, this was the first time, the entire content went into my head to refresh the concepts & damm I never felt a wee bit sleepy. Sure I dint have enough time this week because of my work .. but, Damm I loved it.

A change in strategy - Services to Securtity

Alright Nat section has been successfully completed. After doing a self assessment I have decided to change my strategy. I will be going ahead with the "Security services" part of the lab blueprint. This is because I feel comfortable with the "IP Services" section as compared to the latter.

So this months crack down will on the security from followed by IPv6 & RIP sections. I do have good hands on all aspects of Ipv6 & RIP so I am looking to breez through those labs. So a@ the moment the focus is on security & to quote from the lab blur print the following is what I am looking @

Security

1. AAA
2. Security server protocols
3. Traffic filtering and firewalls
4. Access lists
5. Routing protocols security, catalyst security
6. CBAC
7. Other security features



i just had a look @ the Internetwork expert Ver5 Vol1 labs & was impressed. I am looking forward to get started with the stuff which will be from 6th of April.


So what happened what forced me to change my guard, well I have been reading this wonderful book written by "Robin Sharma" called "The Greatness Guide" here he speaks about facing the fears & coming out strong. I wanted too keep security for the last part of the prep as i was not very confident & honestly a bit scared in the prep.

So taking Robins advice I am moving in a way to change my weakness to strength & overcome my fear. For more insight on how the book is shaping me & my thoughts fell free to read my blog;

Simplifying the Hits & Misses in NAT

We all know that NAT is a essential yet basic tool. But when I spoke with some network engineers they were not able to clearly explain the concept of Hits & Misses in the show ip nat statistics output. So if you are new to nat let me help you out.

If the active translation is for the active mapping or translation present in the nat cause hit , in other words -- hits to an existing mapping.

Misses indicate a new mapping or something that was there in the nat table but has expired & hence causing a new mapping in the NAT table, in other words -- misses causing an attempt to create a mapping, and expired translations.

I am not putting up any configs as a wonderful example & explanation is put up in the following blog http://cciepursuit.wordpress.com/2007/10/07/hits-and-misses-in-ip-nat-statistics/
