brain teasing:

ipv4:
class c: 2^8=256
class b: 2^16=65353
class a:2^32=4.29billion: current world polulation = 5 billion = <= 1 ip/per person = depletion in 2/11, 6/11= (2050= project 10 billion world population)

ipv6:
2^128=3.4×1038 (340 undecillion)=1000 ip ?? /per person = good for next 300 years.

how many IPs you need:
-7x laptops (husband, wife: home work, 1-3 kids)
-7x desktop (husband, wife: home, work, 1-3 kids)
-7x cell phone (husband, wife: home, work, 1-3 kids)
-5x ipad (husband, wife, 1-3 kids)
-home phone
-iphone,
-home suveilance camera
-home networking devices: router, switches
-e-card readers
-any itteligent devices needed to be on network.

When a Man Loves a Woman

Michael Bolton

when a man loves a woman,
can't keep his mind on nothin' else,
he'd change the world
for the good thing he's found.
if she is bad, he can't see it,
she can do no wrong,
turn his back on his best friend
if he put her down.

when a man loves a woman,
he'll spend his very last dime
trying to hold on to what he needs.
he'd give up all his comforts
and sleep out in the rain,
if she said that's the way it ought to be.

well, this man loves you, woman.
I gave you everything I have,
trying to hold on to your hot blood long.
baby, please don't treat me bad.

when a man loves a woman,
down deep in his soul,
she can bring him such misery.
if she is playing him for a fool,
he's the last one to know.
loving eyes can never see.

when a man loves a woman,
he can do her no wrong,
he can never hug some other girl.
yes, when a man loves a woman.
I know exactly how he feels,
'cause baby, baby, you're .
when a man loves a woman....
 








当一个男人爱上女人
他脑海就会一片空白
他会用全世界来交换
他认为找到的好东西
即使她坏他也看不见
在他看来她完美无缺
不惜和最好朋友翻脸
如果他居然看不上她

当一个男人爱上女人
他会花光最后一毛钱
努力满足她一切需索
他会放弃所有的享乐
自己睡在户外大雨中
只要她说那是必要的

这个男人爱上了女人
我会把一切都献给你
努力维系你珍贵的爱
宝贝,可别待我不好

当一个男人爱上女人
从灵魂深处刻骨铭心
她能够让他丢魂落魄
如果把他当傻瓜愚弄
他将会最后一个知道
恋爱中人是如此盲目

当一个男人爱上女人
待她不能有任何错误
他不能再泡别的女孩
这就是男人爱上女人
这一切我都感同身受
因为你就是我的宝贝
当一个男人爱上女人

CCIE Routing & Switching
Number of attempts: 2 (two)
CCIE Lab location(s):
Brussels, August 13 2001 and Tokyo, September 13 2001
CCIE Lab format: 2-day exam (both)
Sponsored by: company (IBM, both)
Written Exam: January 26 2001

Primary CCIE Workbook: CCbootcamp
Classroom training taken: Cisco ICND (2000), in the very beginning of the journey
Short story:
Went to Brussels for the first time after about 6 months preparation, failed in Troubleshooting section
(second day last part), couldn’t sleep after failure, went to Tokyo exactly 1 month after the first attempt,
passed the lab with still 1 hour time left
Moments to remember:
- Sleep in the office for 9 months
- Start practice lab with only 2 routers and lots of loopback interfaces
- Must “borrow” routers from customer premises to build the lab
- First time flying to Europe, first Schengen Visa
- First time flying with Business Class
- Able to take 2nd attempt even the company policy was flying freeze
- Japanese proctor with little English to communicate
- Japanese Keyboard, Japanese Windows
- Get the CCIE number in yellow color post-it paper

Sponsored by: self funding (both)
Written Exam: June 23 2005
Total number of practice lab hours: 600+
Primary CCIE Workbook: Trinetnt (now part of CCbootcamp)
Classroom training taken: none
Short story:
Tried to impress Cisco by taking the lab, had many years experience in security but actually wanted
to learn more into SP technology, went to Brussels after about 4 months preparation, failed with
already above 70% score, couldn’t believe it and got into denial state, went back to Brussels about 6
weeks later, passed the lab this time
Moments to remember:
- Spend countless hours in Ebay to buy personal equipments
- Going back and forth UAE post office to fight for the equipments
- Self funded, so working hard to track expenditure and lab hour
- Again, must “borrow” some equipments from customer premises :)
- Pass Cisco CCIP in the middle of CCIE Security preparation
- Get 9 days off due to the sad demise of UAE sheikh
- The most balanced life between family time and CCIE preparation
- First snowfall in life during second lab attempt
- Lunch in Chinese Restaurant next to Brussels Grand Place after passing. Proper food after eating
only ramen noodles for few days.

Written Exam: February 27 2006 (Metro Ethernet)
Total number of practice lab hours: 240+
Primary CCIE workbook: Internetwork Expert
Classroom training taken: none
Short story:
The track that I have been dying to complete for years, only with about 2 months extensive preparation, relied
completely to Internetwork Expert for video on demand and workbook, the toughest CCIE preparation with very less
spare time from projects and travels, slept maximum 2 to 3 hours every day in the last few weeks before the lab,
passed the lab in first attempt
Moments to remember:
- The toughest CCIE track from the availability of time to study
- The most fun at the same time since I really love the topics
- No personal expense at all from lab fee, trip, workbook, lab
- Sleep 2 to 3 hours maximum everyday anywhere I can: in the taxi, during the flight
- Flying 16 hours to Brussels, 21 hours to go back to Singapore
- Spend whole time in Cisco office to study from 2 days before the lab
- Spend lots of time trying to find soft drinks, fruits, chocolates and any food available during the study in that
weekend in Cisco office
- Great feeling when the unicast and multicast traffic really work across different AS in the my lab day
- Stay until 2 am in Cisco office waiting for the result
- The feeling when I really pass it in first attempt
Inspiring quote: No quotes from 300 movie, but it is really inspiring. “No sacrifice, no victory” (Transformers)

How to Pass the CCIE

So you want to try for the CCIE. Be prepared for a lot of long hours and hard work. But the payoff is worth it! Here are some suggestions.
Studying for the CCIE
Plan to study at least two hours a night for the next six months. Set aside maybe 8:00 PM to 10:00 PM every night as study time. And do it! No excuses! I don't care if there is a really good show on TV, buddies are going out, boss wants you to work late, wife is frisky, or the guy next to you needs CPR. NO EXCUSES! You want to be a CCIE, right? - (from internet)


not because of luck. It was not given. It was not a gift.
It was dedication, hard work, strategy, make sacrifice and so on.
And when the time is right, make a decision and stick with it.” - Himawan Nugroho
