A valid iourc file contains a host-specific registration key generated based on the hostname and host ID of the Linux server running the emulator. The format mimics the following structure: [license] your-hostname = 0123456789abcdef; Use code with caution. Known Constraints of Cisco IOL Images
When using this image in lab environments:
GNS3 can also run this IOL image through its IOU integration. The IOU Virtual Machine provides native execution capabilities for these images. I86bi-linux-l3-adventerprisek9-ms.155-2.t.bin
