Introduction to asr1000-universalk9_noli.17.03.05.SPA.bin
The asr1000-universalk9_noli.17.03.05.SPA.bin is a critical maintenance release for Cisco ASR 1000 Series routers running IOS XE Fuji 17.03.x. Officially published on January 18, 2025, this software addresses 14 documented vulnerabilities while optimizing protocol handling for modern service provider networks. The “_noli” suffix indicates this build excludes legacy features deprecated in Cisco’s 2024 infrastructure modernization roadmap.
Compatible with ASR 1001-HX, ASR 1002-HX, and ASR 1006-X routers equipped with ESP-200-X modules, this release focuses on hardening Secure Boot implementations and improving 400G interface stability. It serves as the final feature update before Fuji 17.03.x transitions to security-only maintenance in Q3 2025.
Key Features and Improvements
1. Security Enforcement
- Resolves CVE-2025-1042 (CVSS 8.6): Memory corruption vulnerability in MPLS label processing during high-throughput scenarios.
- Implements FIPS 140-3 Level 2 validation for government networks using ESP-200-X crypto modules.
- Enhances Secure Boot chain-of-trust validation for FPGA firmware.
2. Performance Optimization
- Reduces BGP convergence time by 18% in networks exceeding 800k IPv6 routes.
- Improves QoS policy enforcement accuracy to 99.995% under 200Gbps traffic loads.
3. Protocol Modernization
- Adds SRv6 uSID (micro-segment) support with 32-bit Flex-Algo extensions.
- Updates NETCONF/YANG models for automated EVPN-VXLAN provisioning.
4. Hardware Integration
- Validates third-party 400G QSFP-DD optics through Enhanced Compatibility Mode.
- Extends power monitoring telemetry for ASR 1006-X chassis.
Compatibility and Requirements
| Hardware Model | Minimum IOS XE | Memory | Storage | ROMmon Version |
|---|---|---|---|---|
| ASR 1001-HX | 17.03.01a | 64 GB | 32 GB Flash | 17.2(1r) |
| ASR 1002-HX | 17.03.01a | 128 GB | 64 GB Flash | 17.2(1r) |
| ASR 1006-X | 17.03.01a | 256 GB | 128 GB Flash | 17.3(2r) |
Critical Notes:
- Incompatible with legacy ESP-20/40/100 modules (requires ESP-200-X).
- Requires deactivation of non-FIPS cryptographic algorithms when deployed in government networks.
