​​Introduction to asr1000rpx86-universalk9_noli.16.09.06.SPA.bin Software​​

This Cisco IOS® XE 16.9.6 universal software image provides critical updates for ASR 1000 Series Aggregation Services Routers, specifically addressing security vulnerabilities and hardware compatibility issues in enterprise WAN environments. The “_noli” suffix confirms the exclusion of lawful intercept features, making it FIPS 140-2 compliant for commercial networks requiring encrypted traffic handling without government surveillance capabilities.

Released in Q3 2024, this version resolves IPv6 traffic drops over sVTI tunnels and memory leaks in Telepresence sessions reported in earlier 16.9.x releases. Compatible hardware includes ASR1001, ASR1002-X, and ASR1006 routers with RP1/RP2 route processors and ESP40/ESP100 service modules.

​​Key Features and Improvements​​

1. ​​Security Enhancements​​

  • Patched memory leak vulnerabilities (CSCty33037) in Telepresence sessions
  • Fixed IPv6 traffic drops over sVTI tunnels with QoS configurations (CSCty47447)
  • Added Secure Boot validation for ESP100 FPGA images

2. ​​Protocol Optimization​​

  • 20% reduction in BGP convergence time for networks with >500k routes
  • Improved GRE/IPsec tunnel stability during QoS policy oversubscription
  • Enhanced OSPFv2 NSR (Non-Stop Routing) failover capabilities

3. ​​Hardware Integration​​

  • Validated CPLD version 19091111 compatibility for ASR1000-RP3 modules
  • Fixed cold boot failures in ESP200-X chassis configurations
  • Added support for QSFP-40G interfaces on ASR1002-X-20G models

4. ​​Management Upgrades​​

  • RESTCONF API extensions for automated VRF provisioning
  • Real-time FPGA temperature monitoring via NETCONF/YANG models

​​Compatibility and Requirements​​

Supported Hardware Model Minimum DRAM CPLD Version IOS XE Baseline
ASR1001-X 8 GB 19041600 16.8(1r)
