Full support for target configuration changes using the commit , show configuration merge , and rollback commands. Demo Image Constraints
To understand this specific file, we first have to break down the nomenclature:
Supports MPLS L3VPNs, RSVP-TE, Segment Routing (SR-MPLS), and basic Segment Routing v6 (SRv6). iosxrvk9demo613qcow2 exclusive
These "demo" images are often sought after because they are lighter than commercial variants, making them ideal for quick lab prototyping. Performance & Compatibility:
QEMU binary: /usr/bin/qemu-system-x86_64 RAM: 4096 MB Network adapters: 4x virtio-net-pci Disk image: iosxrvk9demo613qcow2 (exclusive = checked)
Rename the file to virtioa.qcow2 inside that folder. These "demo" images are often sought after because
The QEMU Copy-On-Write image format, making it highly efficient for disk space and snapshots. Why Version 6.1.3 Matters
