EVE-NG is arguably the most popular platform for hosting IOL images. To use this image in EVE-NG, users upload the file to a specific directory ( /opt/unetlab/addons/iol/bin/ ), ensure it has executable permissions ( chmod +x ), and use a license generator script ( iourc ) to authorize the execution of IOL images within the underlying Linux OS. 2. PNETLab
It is crucial to note that Cisco IOL/IOU images—including I86bi-linux-l3-adventerprisek9-ms.155-2.t.bin —are proprietary Cisco intellectual property. Historically, these images were strictly intended for internal Cisco use and for authorized partners under heavy NDA.

What specific are you trying to build?
Unlike open-source operating systems, IOL images require explicit validation locally. Simulators read a text file named iourc stored in the same directory as the binary. The file contents must format precisely to map your virtual host machine's name to a mathematical key generated for authorization: [license] gns3vm = 1234567890abcdef; Use code with caution. 3. Importing the Appliance Template EVE-NG is arguably the most popular platform for
If you are studying for Cisco certifications, this image provides the necessary feature sets for complex BGP and OSPF labs that smaller images cannot handle. Testing and Validation
Unlike or EVE-NG using QEMU (which emulates router hardware), IOU/IOL images are native Linux processes . This means: PNETLab It is crucial to note that Cisco
If prompted, select the Cisco IOU L3 appliance and select the 15.5(2)T image from the list. Step 3: Licensing (IOURC)
