This image is part of the official Cisco reference platforms. CML natively supports this image, providing stable resource allocation and accurate feature representations for topology design. 2. EVE-NG (Emulated Virtual Environment Next Generation)
: vIOS images are reported to be "one of the slowest known from Cisco" in terms of performance, and "might be useful for non-traffic labs". Unlike more modern alternatives like Cisco CSR1000v, the IOSv images can exhibit high latency—even showing ping times between 6 and 7 seconds when interacting with physical networks. Vios-adventerprisek9-m.vmdk.spa.157-3.m3
Ideal for studying Multi-Protocol Label Switching and Layer 3 VPNs. This image is part of the official Cisco reference platforms
: This represents the software version, specifically Cisco IOS Release 15.7(3)M3 . Usage in Network Labs EVE-NG (Emulated Virtual Environment Next Generation) : vIOS
Unlike lower-tier feature sets, the adventerprisek9 license enables complete Multiprotocol Label Switching (MPLS) frameworks. This allows engineers to build virtualized ISP environments containing: Label Distribution Protocol (LDP) MPLS Layer 3 VPNs (L3VPN) Virtual Private LAN Service (VPLS) Traffic Engineering (MPLS-TE) Network Automation and Programmability
: To run efficiently in a simulator, it typically requires roughly 512 MB of RAM per instance. Use Cases in Simulation
