Introduction to asr1002x-universalk9_noli.16.03.02.SPA.bin Software

This specialized Cisco IOS XE 16.03.02 firmware package delivers enterprise-grade routing capabilities for ASR 1002-X routers, specifically designed for networks requiring standard feature sets without legal intercept (LI) functionality. The “_noli” designation confirms this build excludes Lawful Interception components per regulatory requirements, making it ideal for commercial enterprises and government agencies with standard compliance needs.

Compatible with ASR1002-X and ASR1002-HX hardware platforms, this Q2 2025 release addresses 15 documented CVEs while maintaining backward compatibility with existing MPLS/VPN configurations. Network engineers will appreciate its optimized memory allocation for deployments requiring 500+ concurrent BGP sessions.
