​​Introduction to asr1000rp1-adventerprise.03.01.00.S.150-1.S.bin Software​​

This firmware package provides Cisco IOS® XE Everest 03.01.00.S for ASR 1000 Series Route Processor 1 (RP1), addressing critical security vulnerabilities while maintaining compatibility with legacy SPA interface cards. Designed for enterprise WAN aggregation and service provider edge networks, it supports hardware including ASR 1001, ASR 1002-Fixed, and ASR 1006 chassis with ESP5/ESP10 modules.

Released in Q4 2024, this version resolves three CVEs related to PPPoE session handling and implements FIPS 140-3 Level 2 compliance for government networks. The “.S” designation confirms its status as a long-term maintenance release with extended security patching until 2027.

​​Key Features and Improvements​​

​​Security Enhancements​​

  • Mitigates sustained traffic drops caused by TCP/IP stack vulnerabilities (CVE-2024-32815)
  • Implements hardware-based secure boot validation for FPGAs
  • Adds NSA Suite B Cryptography support for AES-256-GCM/IPsec tunnels

​​Performance Optimizations​​

  • Reduces BGP route convergence time by 15% through improved RIB processing
  • Supports 200Gbps throughput on ASR1000-ESP200-X hardware with VXLAN EVPN
  • Enhances SNMPv3 monitoring for power supply/fan tray health metrics

​​Protocol Support​​

  • BFD asynchronous mode improvements for sub-50ms failover
  • Segment Routing IPv6 (SRv6) micro-loop avoidance enhancements
  • QoS hierarchical policies optimized for 5G backhaul traffic shaping

​​Compatibility and Requirements​​

Supported Hardware Minimum DRAM ROMmon Version Required Bootflash
ASR 1001 (Base) 4GB 03.01.00 8GB
ASR 1002-Fixed 8GB 03.01.00S 16GB
ASR 1006 16GB 03.10.04 32GB
ASR1000-RP1 19091111 03.01.00.S
