I have done mostly rack rentals so far and for pure layer 2 it’s a must but I want to mix with Dynamips for labs that are not heavy on layer 2. I wanted to use the configs provided for vol1 in Dynamips but the interfaces does not match since the serial interfaces is in a different slot. The NM-16ESW only has 16 ports instead of 24 and there are also some differences on the backbone routers. Going through each configuration before each lab would take a lot of time and be very tedious. Since I couldn’t find anything that suited my need I wrote a shellscript to convert the configs for me. Disclaimer: I have very little experience with scripting and if you want to use the script, do it at your own risk. The code is very ugly and can probably be more efficient but it works. If you find any errors please post them in comments. The script uses sed to replace text in the configs. You can find the script here. The only thing you need to modify is the newdir=”/home/reaper/INE/configs/Dynamips”. Change it to your homedir, I store the files for r1-r6 etc in INE/configs and the script creates the Dynamips dir.
