: Minimum 16 GB (20 GB or more is recommended for stability in version 7.2.2). Disk : 8 GB - 16 GB of space. NIC Type : Virtio-net-pci. 3. Installation Steps (EVE-NG)
represents a specific point in the software’s evolution, balancing stability with modern features like Segment Routing (SR) and enhanced telemetry. 2. Performance and Use Cases
Flexible Algorithm (Flex-Algo) to create customized paths based on latency or cost constraints.
The "Xrv9k-fullk9-7.2.2" refers to a specific software image for Cisco devices, likely within the ISR (Integrated Services Router) or possibly the ASR (Aggregation Services Router) series, given the nomenclature. Let's decode this:
16 GB (16384 MB) is necessary for the full image, although it may boot with less. Disk: A virtualized QEMU hard disk. Xrv9k-fullk9-7.2.2
Upload your Xrv9k-fullk9-7.2.2.qcow2 file to the created directory. Rename the disk file so the hypervisor can recognize it as the primary bootable drive:

Use Cases for Version 7.2.2
With the introduction of the Linux-based architecture in the 7.x train, network engineers can integrate this exact software image into automated testing pipelines. Using tools like Ansible, Terraform, and Git, configuration changes can be pushed to an ephemeral instance of the router in a virtual sandbox, verified using automated test suites, and torn down before applying the changes to physical production hardware. 3. Advanced Protocol Verification
The 7.2.2 release brought several "deep" shifts to how service provider networks are managed: Model-Driven Programmability: This version heavily leverages YANG data models : Minimum 16 GB (20 GB or more
Class-based weighted fair queueing (CBWFQ), policing, and shaping adapted for virtual interfaces. Deployment Environments and System Requirements
Full support for Segment Routing over IPv6 (SRv6) and MPLS data planes, allowing for policy-driven traffic engineering without resource-intensive RSVP-TE.
16 GB RAM minimum (20 GB to 24 GB recommended depending on routing table sizes). Storage: 30 GB of hard disk space. Supported Hypervisors and Orchestrators
Runs the standard IOS XR daemons for routing protocols (BGP, OSPF, IS-IS), management infrastructure, and configuration databases. It operates as a set of Linux-based processes. Performance and Use Cases Flexible Algorithm (Flex-Algo) to
