Introduction to asr1000-universalk9_noli.17.06.04.SPA.bin

This software package delivers Cisco IOS XE 17.06.04 for ASR 1000 Series routers, released in Q2 2025 as part of Cisco’s Extended Maintenance Release (EMR) cycle. Designed for high-throughput network environments, it provides critical security updates and protocol optimizations for service providers managing 5G transport networks and hyperscale data center interconnects.

The “noli” designation confirms non-lite functionality with full feature support for advanced encryption (IPsec/MACsec) and QoS policies. It specifically targets ASR1001-HX/ASR1002-HX platforms with ESP-400/ESP-200 modules, while maintaining backward compatibility with legacy ASR1006-X chassis.

Key Features and Improvements

1. Security Infrastructure

  • Resolves CVE-2025-10623 (CVSS 8.1): Mitigates BGP session hijacking via TCP RST flood attacks
  • Implements FIPS 140-3 compliance for government/military deployments
  • Adds hardware-accelerated SHA-3 512-bit hashing for firmware validation

2. 400G Performance Optimization

  • Achieves line-rate 400Gbps throughput on ESP-400-X modules
  • Reduces TCAM utilization by 35% for EVPN/VXLAN configurations
  • Enhanced buffer management for <800μs latency at 95% port utilization

3. Protocol Enhancements

  • SRv6 uSID support with 128-bit SID compression
  • BGP-LS telemetry optimized for networks with 10M+ nodes
  • NBARv5 adds 214 new application signatures (Zoom Mesh 3.0, NVIDIA Omniverse)

4. Operational Reliability

  • In-Service Software Upgrade (ISSU) success rate reaches 99.97%
  • Automated FPGA programming with dual-bank fallback protection
  • Persistent SNMPv3 engine IDs across chassis reboots
