These images are sometimes optimized by community members to run more efficiently on low-resource hardware, making it easier to run large-scale topologies on a single laptop. How to Use IOS-XRv 6.1.3 (QCOW2) in Your Lab

: Unlike standard IOS, IOS XR uses a two-stage process. You must enter global configuration mode, make changes, and then use the commit command to apply them.

Running a robust operating system like IOS XR in a virtual container requires specific resource allocations. Below are the standard hardware and hypervisor metrics required to launch an exclusive iosxrvk9demo613qcow2 instance smoothly. Resource Metric Minimum Requirement Recommended for Lab Environments

: Scripts are available to automate the setup of IOS XRv in Vagrant environments . Key Features and Limitations

When you launch the image without applying a production license, the router boots into Demo Mode by default. In this state, the virtual router is subject to a strict throughput rate limit of 200 Kbps . While 200 Kbps is sufficient for routing protocol updates (like BGP or OSPF), it is inadequate for transferring real user data or testing high-speed forwarding performance. This is often the main constraint that makes the free demo image "exclusive" to learning and verification rather than production use.

: Corresponds to IOS XR Software Release 6.1.3 , a stable environment deeply favored for its predictable handling of BGP, MPLS, and segment routing.

Connect to your EVE-NG server using an SSH client or SFTP tool like WinSCP.

Release 6.1.3 helped bridge the gap between traditional network management and modern network automation. It supports:

Access your EVE-NG server via SSH (using an FTP or terminal client like PuTTY or WinSCP).

If you are operating inside GNS3, utilizing the community appliance marketplace simplifies the procedure:

The "v" stands for virtual. This is the virtualized version of the OS, designed to run on hypervisors like VMware, KVM, or VirtualBox.
