Dynamips Router emulator

Introduction

Dynamips is a Cisco router emulator written by Christophe Fillot. It emulates 2691, 3620, 3640, 3660, 3725, 3745, and 7206 hardware platforms, and runs standard IOS images. In Chris’ own words:

This kind of emulator would be useful to:

· Be used as a training platform, with software used in real world. It would allow people to become more familiar with Cisco devices, Cisco being the world leader in networking technologies ;

· Test and experiment features of Cisco IOS ;

· Check quickly configurations to be deployed later on real routers.

Of course, this emulator cannot replace a real router, it is simply a complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA/CCNP/CCIE exams.

Beijing - China

I am not sure how to describe Beijing China, maybe everyone who goes their simply use the world 'Amazing' because it will be nearly impossible to describe it. I had a personal driver and tour guide which significantly simplify my trip around. Of course, it was a business trip and I didn't have as much time as I needed to see everything from Beijing but I will try to share couple of pictures and some of my impressions. I will start with the food. I remember when I was younger there was so many Chines restaurants in the neighbourhood and I could eat Chines food everyday, and at every time - my parents were joking that I will became a Chines if I continue to eat only Chines, but it was so good and I didn't care ;-) In Beijing I tried so many different things and I am amazed by the quality of the food, and most amazingly I didn't have any problems with my stomach - which was a good sign ;-) . I uploaded few photos from my album, which are from different places I

So, You Want To Be a CCIE?, Part 2

Prepare yourself for "game day" of the CCIE exams in this second part of a two-part primer on Cisco's highest-level cert by the columnist of TCP Q&A. by Scott Morris July 2005 — Editor's note: To read part one of this two-part series, go here . There’s never any point in time when you will truly know everything. Similarly, there’s never any point in time when the exam will be as bad as you may think it is until you try it! So you can spend years and years “studying” for the CCIE written exam and never think you know enough to take it. But you won’t know until you try. And you may also surprise yourself along the way: You probably know more than you give yourself credit for. (Either that or you’re really lucky!) --------------------------------------------------------- http://tcpmag.com/features/article.asp?EditorialsID=91 ---------------------------------------------------------
