| Component | Meaning | Significance | | :--- | :--- | :--- | | | IOS XRv Router | This identifies the virtualized version of Cisco’s IOS XR operating system. Unlike traditional Cisco routers that run on specialized hardware, IOS XRv is designed to run on standard x86 servers. | | k9 | Encryption (3DES/AES) | The "k9" designation indicates that the image includes strong encryption capabilities (3DES and AES), which are required for secure VPN connections, SSH, and other cryptographic functions. Images without this marking may have encryption limited or removed due to export restrictions. | | demo | Demo / Trial Version | This marks the image as a demonstration or evaluation copy. Demo images are typically free to download and use for learning, but they come with limitations such as throughput caps (e.g., 2 Mbps) or restricted feature sets. Full-production images require a paid license. | | 613 | Version 6.1.3 | This refers to Cisco IOS XR software release 6.1.3. Version numbers follow Cisco’s standard scheme where the first digit (6) indicates the major release, the second digit (1) indicates the minor release, and the third digit (3) is the maintenance or patch level. | | qcow2 | File Format | QEMU Copy-On-Write version 2—the native disk image format for KVM/QEMU virtualization. QCOW2 supports features like snapshots, compression, encryption, and thin provisioning, making it ideal for virtual machine management. | iosxrvk9demo613qcow2
