New Version of Dynagen Out!

Version 0.11.0 of Dynagen has just been released. The Dynagen tutorial has also been updated with info on how to set up PIX emulation. This is great news for those preparing for their security CCIE (and for those of us who want to play!). Check out the release notes here.

Tutorial: BGP Conditional Route Injection with inject-map

One of the great new features that was introduced in IOS 12.3 is BGP conditional route injection. With conditional route injection we can insert more specific routes into a BGP table based on the existance of another route. Most of the routes in the current internet BGP table consists of aggregate routes. This is used to minimize the size and number of routes in global BGP routing table. The aggregation of routes can sometimes obscure more specific and accurate routing information. Wouldn’t it be cool if we could control and “un-aggregate” those routes on demand? Well that’s kinda what BGP conditional route injection does. It allows us to originate a more specific prefix into the BGP routing table based on an existing aggregated route.

Emulating JunOS

Himawan Nugroho has updated his awesome blog with information on how to set up JunOS on an emulator using jqemu. Awesome! Dynamips/Dynagen to study for your CCIE, Jqemu to study for your JNCIE!

New Blindhog Dynamips Video

Blindhog has released another great Dynamips video tutorial showing how to use a windows loopback interface to connect to your dynagen/dynamips lab in GNS-3. Check it out!

Tutorial: How to use Cisco MQC & NBAR to filter websites like Youtube

I was asked a great question by one of my clients regarding filtering of websites. He had filtered youtube and google video at his proxy server but with the number of different video sites popping up (metacafe, jibjab etc etc), his filters just couldn’t keep up…and neither could his bandwidth!
One solution to this problem is [...]

Tutorial: How to set up a Cisco router as a Web Server

Need a basic webserver? Did you know that little Cisco router in the corner can act as as one? Well, now you do! In this article we will be setting up a basic webserver on a cisco router. I will be using dynamips to demonstrate this, but it works just as well on a real router! I was using dynamips to simulate a QOS lab where i wanted to mark certain HTTP traffic for shaping. I needed a way to simulate a webserver so that I could test it. Enter the ip http server command!

Tutorial: How to set up a basic Dynamips Lab using Dynagen, Part 1

I get a lot of requests from students asking how they can practice some of the topics I teach on my Cisco courses. Cisco equipment can be pretty expensive especially when you are starting out your networking career, and not having anything to practice on makes that barrier to entry that much higher. Enter Dynamips. Dynamips is a Cisco hardware emulator. Its like VMWare for Cisco! It emulates a basic Cisco hardware platform so all you need to add is an IOS.
