Timos-sr-13.0.r4-vm.qcow2

Because it is a full router, you can test control plane vulnerabilities, BGP Flowspec policies, or DDoS mitigation techniques without risking hardware.

Version 13.0.r4 stabilizes the Segment Routing Traffic Engineering (SR-TE) policy infrastructure. You can build a 5-node virtual topology using libvirt, configure IS-IS with SR extensions, and test path computation with PCEP (PCE Protocol). Timos-sr-13.0.r4-vm.qcow2

Before deploying a complex Segment Routing policy, run it here. The vm.qcow2 image behaves exactly like a 7750 SR-12 line card—because the data plane is the same binary, just virtualized. Because it is a full router, you can

Running Timos-sr-13.0.r4-vm.qcow2 requires proper resource allocation. Below are the typical minimum and recommended specs for this specific version. Before deploying a complex Segment Routing policy, run

| Component | Minimum Requirement | Recommended (Lab) | Recommended (Production) | | :--- | :--- | :--- | :--- | | vCPU cores | 2 | 4 | 8+ | | RAM | 8 GB | 16 GB | 32-64 GB | | Disk (qcow2) | 20 GB (thin provisioned) | 40 GB | 100 GB+ (thick) | | NICs | 4 virtual interfaces | 8 virtual interfaces | 16+ (SR-IOV) | | Hypervisor | KVM/QEMU 4.0+ | KVM + libvirt | VMware ESXi (converted) |

Important Constraints:

Before upgrading a physical 7750 SR chassis from 12.0 to 13.0.r4, operators run the same version in a VM with downtime simulation scripts.
