Introduction to asr1002x-universalk9.16.06.01.SPA.bin

This Cisco IOS XE software package (asr1002x-universalk9.16.06.01.SPA.bin) serves as a critical maintenance update for ASR 1002-X routers operating in enterprise WAN and service provider edge environments. Released under Cisco’s Extended Maintenance cycle per web10’s EoL documentation, this universal image addresses multiple Common Vulnerabilities and Exposures (CVEs) while optimizing hardware utilization for ASR1002-X chassis with RP2 processors.

Compatible with both fixed-configuration ASR1002-X models and modular ASR1006/1009-X chassis, this release focuses on sustaining operational stability for networks transitioning to Cisco’s Catalyst 8500 series platforms. The “_noli” suffix confirms exclusion of lawful intercept modules, maintaining compliance with standard enterprise security policies.
