Cisco Iou Keygen.py
Cisco IOU stands for “IOS on Unix”. Cisco is offering remote lab rentals and it seems they are shifting from real hardware to a “GNS3 / Dynamips” alike solution. This is the Official Cisco method of running Cisco IOS for routers (AND switches as well!) on Unix. Apr 24, 2014 The IOU license script shouldn't be run using bash (aka shell), as it is written in python. (They're different interpretors) Grab the script from: post28850.html#p28850 which will work with python 2.7 or python 3. Generate the license. After running this command, a file called iourc.txt will be created. Copy and paste the license key in the file to the Preference IOS on UNIX section of GNS3.
- Cisco IOS-On-UNIX is a fully wking version of Cisco IOS that runs as a user mode Linux process. IOU suppts all Cisco IOS platfm independent protocols and features. IOU allows you to build out a netwk topology on a single PC without the need f physical routers.

When I wanted to add IOU L2 Switch image on GNS3, I got the following license error.
When I checked the license, I realized there was no license key.
I explained the solution :
1- Access the shell of your VM
2. Download the Keygen using the following command.
Before doing that, we need to have EIGRP metric calcualte formula (As only K1 and K3 are not 0 by default).
As we need to modify bandwidth and delay value based on given metric, we simply change the formula as follows:
Let start,
This is topology of R5 lo0 in R1
First we will emphasize first two links which si 20 to 5 ratio. It is same as 4 to 1 ratio.
Looking at the feasible distance of ‘158720’ through R1>R2>R5. Fa1/1 of R1(R1>R3>R5) would need tohave 4 time higher than to achieve 4 to 1 ratio. (4×158720 = 634880). We need put that metric to formula to get bandwidth value.

In the end, we want to have 20/5/1 ratio, we have to put variance value to 20 and configure Fa1/1 of R1 to bandwidth value of 5102 Kb.
Let see traffic share ratio
We now have 1 to 4 ratio. Let focus on third one. The metric need to be 20×158720 = 3174400. Let put it into formula to get bandwidth. Keep in mind that delay in this path is 7000.
Before we move forward that, Reported Distance of path R1>R4>R5 should be lower than FD. So we modify the bandwidth value of Fa2/1 of R4 to 1GB.

Ok now we have path R1>R4>R5 in routing table of R1.
We now modify the bandwidth value of R1’s Fa2/0 which is R1>R4>R5 link to 855 Kb.

Now we have the ratio of 20/5/1.
