Mad Dynamips/Dynagen Topology 1.1

I noticed a few mistakes in my previous topology. Namely I had no routers with more than 1 connection to each other. This is essential for a number of tests. I’ve re-done the topology now. Look closely at Router’s 7 and 14 – There is a new interface connecting them. This time I’ll upload my IP addressing scheme as well as my config files. You’ll need to customise the settings and idlepc values for yourself.

Once again you’ll need to click the picture for the full picture.

Here is my .pdf file which contains my IP addressing scheme. You can see that most links are /30 point to point links, but there are a few /24’s as well where more than 2 routers connect in the same broadcast domain. Click here for the topology

Thankfully you won’t have to put this info in every time, as it’s already saved in my configuration files which are auto loaded. Download the configuration files here

Now it’s up to you to create labs based on this topology. I’ve got a number of ideas for BGP as that’s what I’m studying now, so stay tuned!
