Integrating with EVE-NG (Professional and Community)

EVE-NG is the preferred emulator for CCIE STP studies.

  1. Upload the QCOW2:

    • Using WinSCP or SCP, copy xrv9k-fullk9-x-7.1.1.qcow2 to: 
      /opt/unetlab/addons/qemu/xrv9k-7.1.1/
    • Rename it to: virtioa.qcow2

  2. Create the node in EVE-NG:

    • In the lab canvas, right-click → Add Node.
    • Choose Type: Cisco → Device: xrv9k.
    • Set the version to match your folder name (xrv9k-7.1.1).
    • Allocate 4 vCPUs and 8192 MB RAM.

  3. Run the fix permissions script:

    /opt/unetlab/wrappers/unl_wrapper -a fixpermissions

  4. Start and console. Boot time is ~4-5 minutes. Be patient.

2. Review of Version 7.1.1

Version 7.1.1 is significant because it sits in the "Amsterdam" release train.

  • Stability: The 7.1 train is widely regarded as stable for service provider labs and testing. It is more mature than the newer 7.x trains but includes modern features missing in the 6.x lifecycle.
  • Key Features in this Train:
    • Enhanced Segment Routing (SR-MPLS and SRv6) support.
    • Model-Driven Programmability (YANG models, NETCONF/RESTCONF) is fully mature here.
    • Improved telemetry streaming (gNMI/gRPC), which is critical for modern SP automation.
  • App Hosting: Support for third-party containers (Docker) running directly on the XRv9000 (IOx), allowing for edge computing simulations.

Features of XRV9K

  • Wide Range of Features: Supports a vast array of routing protocols (RIP, OSPF, EIGRP, BGP), multicast protocols, and other advanced networking features.
  • Modularity: Offers modular architecture allowing for the installation of various modules to extend its functionality.
  • High Performance: Despite being a virtual appliance, the XRV9K can handle high-speed network simulations and testing.
  • IOS-XE Software: Running on IOS-XE, it provides a modern and highly versatile software architecture.
