It simulates the full control plane of IOS XR, making it excellent for testing control plane traffic and protocols.

Engineers use version 6.1.3 to practice and validate core service provider features:

As a single VM, it lacks physical distributed architecture representation. Certain commands involving specific hardware paths or line card components ( show controllers , ASIC telemetry) will return empty or stub data.

Because this is a virtualized demo image and not a full production instance (like the 64-bit IOS XRv 9000), it has significant constraints:

If you are using or EVE-NG , ensure you have allocated at least 3GB3 cap G cap B

The 6.1.3 demo image remains highly relevant for specific legacy validation scenarios and resource-constrained environments. 1. Protocol Validation and Lab Testing

For educational purposes, demo images are invaluable. They allow students to gain practical experience with real software in a controlled environment.
