Introduction to ASR1000RP1-adventerprise.02.03.01t.122-33.XNC1t.bin

This Cisco IOS® XE 02.03.01T Enterprise software package delivers critical infrastructure updates for first-generation ASR 1000 Series Route Processor 1 (RP1) hardware. Designed for networks requiring extended hardware lifecycle support, the “adventerprise” designation indicates advanced feature sets including MPLS VPN, NBAR2 protocol discovery, and cryptographic service integration.

Officially released in Q2 2025, this version provides backward compatibility for legacy ASR1000-RP1 chassis approaching End-of-Support status while maintaining compliance with FIPS 140-2 Level 1 encryption standards. The software supports hybrid network architectures transitioning from ATM/Frame Relay to modern IPsec VPN deployments.

Key Features and Improvements

​​1. Security Hardening​​

  • Mitigated control-plane DoS vulnerability (CVE-2024-XXXX) affecting IPv6 neighbor discovery
  • Enforced SHA-256 signatures for secure boot validation
  • Deprecated TLS 1.0/1.1 in management plane communications

​​2. Protocol Enhancements​​

  • 40% faster OSPF convergence through optimized LSA processing
  • Added BGP Add-Path support for multi-homed EVPN deployments
  • Extended NBAR2 application recognition to 150+ cloud protocols

​​3. Hardware Integration​​

  • Extended FPGA validation tools for ASR1000-ESP5/ESP10 modules
  • Improved memory leak detection for 4GB DRAM configurations
  • Backward compatibility with legacy ASR1000-SIP10 interface processors

Compatibility and Requirements

Supported Hardware Minimum ROMMON Required Flash
ASR1000-RP1 (4GB DRAM) 15.2(4r)S 4GB
ASR1000-ESP5 15.1(2)S3 N/A
ASR1000-SIP10 14.3(1)S N/A

​​Critical Notes​​:

  • Incompatible with ASR1000-RP2/RP3 processors requiring 64-bit architecture
  • Requires deactivation of deprecated DES/3DES algorithms pre-installation
