The file i86bi-linuxl2-adventerprisek9-m-152-may-2018.bin is a specific iteration of the Cisco IOS software image designed for the IOU (IOS on Unix) and IOL (IOS on Linux) simulation environment. It is widely used in network engineering circles for lab simulations, specifically within the GNS3 (Graphical Network Simulator-3) and Cisco VIRL (Virtual Internet Routing Lab) platforms.
This specific image is notable because it is a Layer 2 (L2) image, meaning it supports switching features (VLANs, Spanning Tree, EtherChannel) which are often missing or limited in standard router (Layer 3) IOU images. i86bi-linuxl2-adventerprisek9-m-152-may-2018.bin download

Surprisingly, this Layer 2 image supports a limited subset of IP routing (static routes only). To enable:
Switch(config)# ip routing
Switch(config)# interface vlan 1
Switch(config-if)# ip address 192.168.1.10 255.255.255.0
