The i86bi_linuxl2-adventerprisek9-m_152_may_2018.bin file is a binary software image for a Cisco device, which is likely a router or a switch. The filename can be broken down into several parts: i86bi_linuxl2-adventerprisek9-m_152_may_2018.bin
The file i86bi_linuxl2-adventerprisek9-m_152_may_2018.bin is a specifically designed to run as a Layer 2 switch in a virtualized environment, typically on Cisco IOL (IOS on Linux) . Advanced versions like Rapid-PVST+ and MST
Port-security, DHCP snooping, and Dynamic ARP Inspection (DAI). Where is it used? Layer 3 Switching: SVIs and routed ports
| Missing Feature | Why it matters | | :--- | :--- | | | Cannot run router ospf , ip route , bgp , or ip routing . This is a pure switch, not a router. | | No NAT | Cannot translate IP addresses. | | No VRF | No virtual routing/forwarding instances. | | No MPLS | Cannot do MPLS switching or L3VPN. | | Limited ACLs | Only MAC ACLs or VLAN maps. No advanced L3 ACLs (requires L3 image). | | No hardware forwarding | All switching is done in software (Linux CPU). Performance is ~50-100 Mbps per interface in GNS3. |
Since this is a image (no ip routing command):
