Introduction to asr9k-9000v-nV-x64-1.0.0.0-r662.x86_64.rpm

This RPM package provides virtualization extensions for Cisco ASR 9000v routers running IOS XR 6.6.2, specifically designed for cloud-native network function (CNF) deployments. Released under Cisco Security Advisory cisco-sa-asr9k-vnf-2025 (April 2025), it resolves critical memory allocation vulnerabilities in multi-tenant virtual routing instances while introducing hardware-accelerated vSwitch optimizations.

The “nV” designation indicates native virtualization support for Kubernetes-orchestrated workloads, enabling ASR 9000v platforms to host up to 64 isolated network slices per chassis. Compatible with ASR-9912 and ASR-9922 hardware running IOS XR 6.6.2 base images, this update maintains backward compatibility with 6.5.x virtual service configurations.

Key Features and Improvements

1. ​​Virtualization Performance Enhancements​​

  • 40% reduction in vSwitch latency through SR-IOV hardware offloading
  • Fixed memory leak in Docker container orchestration subsystem (CVE-2025-33591)
  • Added support for 8K virtual routing instances per NPU cluster

2. ​​Security Hardening​​

  • Implemented FIPS 140-3 compliant encryption for VM-to-VM communication
  • Patched privilege escalation vulnerability in KVM hypervisor management
  • Introduced zero-trust microsegmentation policies for CNF workloads

3. ​​Operational Efficiency​​

  • 35% faster VM provisioning through parallelized resource allocation
  • Integrated Prometheus metrics exporter for real-time telemetry
  • Extended Ansible Tower API support for automated scaling

Compatibility and Requirements

Supported Platforms Minimum Resources IOS XR Base Version Virtualization Licenses
ASR-9912 with NCS-57D3 128GB RAM / 1TB SSD 6.6.2 Network Advantage + VNF-64
ASR-9922 with LightSpeed 256GB RAM / 2TB NVMe 6.6.2 Network Ultimate + CNF-Premium
Cisco UCS C480 M5 Server 64 vCPUs / 512GB RAM N/A Enterprise Cloud Suite

​​Critical Constraints​​:

  • Incompatible with 32-bit ASR 9000 legacy chassis
  • Requires Cisco NX-OS 10.4(2)F for hybrid cloud deployments
  • vGPU acceleration mandates separate CUDA license
