AToM and C37xx

I spend couple of hours yesterday playing with "Any transport over MPLS" and it works. It's easy to configure and easy to troubleshoot,anyway, I am not writing this post because it's easy to configure some MPLS application but because I tried it first on cisco 3725 and I hit some issues - so my advice is - if you are using dynamips and want to try some MPLS features just don't do it on 37xx platforms, use 72xx.

IOS on Unix (IOU)

source http://evilrouters.net/2011/01/18/cisco-iou-faq/ What is IOU? From the Cisco Engineering Education web site (a long time ago): IOS on Unix (IOU) is a fully working version of IOS that runs as a user mode UNIX (Solaris) process. IOU is built as a native Solaris image and run just like any other program. IOU supports all platform independent protocols and features. What operating systems does IOU run on? It is my understanding that, initially, IOU was Solaris (SPARC) only. Nowadays, however, there are also builds for OS X and Linux. Similar to dynamips, IOU allows you to build out a network topology on a computer, without the need for physical routers. This is useful for validating designs, proof-of-concept testing, and certification self-study. Is my system compatible with IOU? You will need to be running the operating system that your IOU image were built for, obviously. Other than that, there are no special requirements to run IOU. It is not very CPU- or memory-intensive, unlik...

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 ...
