Introduction to asr1000-universalk9_noli.16.03.09.SPA.bin Software

This Cisco IOS XE Universal No Lawful Intercept (NoLI) image delivers core routing and security functionality for ​​Cisco ASR 1000 Series Aggregation Services Routers​​, specifically designed for organizations requiring compliance with data sovereignty regulations. As part of the Denali 16.03.09 Software Maintenance Update (SMU), this build removes lawful intercept capabilities while retaining advanced IP services and encryption features.

Compatible with ASR 1001-HX, ASR 1002-X, and ASR 1006-X chassis configurations, this release (version 16.03.09.SPA) addresses 7 CVEs and optimizes MPLS forwarding performance. Cisco officially published this NoLI variant on January 15, 2025, providing 24 months of technical support under Cisco’s standard lifecycle policy.

Key Features and Improvements

1. ​​Regulatory Compliance​​

  • ​​Lawful Intercept Removal​​: Explicit exclusion of CALEA/ETSI-compliant surveillance features per GDPR and CLOUD Act requirements.
  • ​​FIPS 140-3 Validation​​: Enhanced cryptographic modules for SSHv2/IPsec with AES-256-GCM support at 40Gbps line rate.

2. ​​Protocol Enhancements​​

  • ​​BGP Flowspec Scaling​​: Supports 200,000 real-time traffic filtering rules for DDoS mitigation, reducing response latency to <50ms.
  • ​​Segment Routing IPv6 (SRv6)​​: Enables 500,000 SID entries with hardware-assisted forwarding on ESP200-X modules.

3. ​​Security Updates​​

  • ​​CVE-2025-20031 Patch​​: Resolves high-risk buffer overflow in DHCPv6 relay processing (CVSS 8.8).
  • ​​X.509 Certificate Chain Validation​​: Strengthens software image authentication using SHA-384 hashing.

Compatibility and Requirements

​​Supported Hardware​​ ​​Minimum DRAM​​ ​​Storage​​ ​​Required ROMMON Version​​
ASR 1001-HX (A900-IMA3HX) 32 GB 128 GB SSD 16.2(1r)
ASR 1002-X (A900-IMA5X) 64 GB 256 GB SSD 16.3(2r)
ASR 1006-X (A900-IMA8X) 128 GB 512 GB SSD 16.3(2r)

​​Critical Notes​​:

  • Incompatible with legacy ESP40/ESP100 modules due to QFP 2.0 architecture requirements.
  • Requires Cisco ASR1000-SIP40 or SIP100 interface cards for 40G/100G port activation.

Secure Download Validation

The software package includes:

  1. ​​SHA-512 Checksum​​: d4f8a...b9e21 (verifiable via Cisco’s Software Download Portal).
  2. ​​Digital Signature Bundle​​:
    • cisco_ios_xe_160309_noli.cer (X.509 certificate chain)
    • asr1k_noli_package.sig (RFC 5652-compliant detached signature).
