Because of this small resource footprint, a modern laptop with a 6-core processor and 16 GB of RAM can easily run topologies consisting of 15 to 20 concurrent virtual routers without breaking a sweat. Conclusion

Which are you using (GNS3, EVE-NG, or CML)?

: Deep support for Multiprotocol Label Switching (MPLS), Layer 2 VPNs (L2VPN), and Layer 3 VPNs (L3VPN). Security Features : Zone-Based Firewall (ZBFW) and Advanced Inspection Control. IPsec VPNs with support for GETVPN, FlexVPN, and DMVPN. TrustSec support for identity-aware networking. Vios-adventerprisek9-m.vmdk.spa.157-3.m3

The vios-adventerprisek9-m.vmdk.spa.157-3.m3 image mirrors the behavior of physical Cisco ISR (Integrated Services Routers). It provides deep protocol coverage, making it ideal for standard routing simulations:

: Denotes that the image is compiled to target a specific operational memory profile or baseline architecture footprint (frequently mapped to standard modular/mainline execution). Because of this small resource footprint, a modern

: 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.

: Indicates Virtual IOS , a version of Cisco's operating system optimized to run on standard x86 computer processors via a hypervisor. Security Features : Zone-Based Firewall (ZBFW) and Advanced

vIOS is a router switch. It does not support Layer 2 switching features (such as VLAN configuration, STP, or port-channels) — for those, you need a dedicated vIOS-L2 or IOSvL2 image.
