Introduction to ASR1000RP1-adventerprisek9.03.13.06.S.154-3.S6-ext.bin

This Cisco IOS® XE 03.13.06.S software package delivers critical updates for first-generation ASR 1000 Series Route Processor 1 (RP1) hardware, focusing on enterprise-grade routing and advanced security protocols. The “adventerprisek9” designation confirms full support for MPLS VPN, IPv6 multicast routing, and hardware-accelerated encryption services, making it ideal for networks transitioning from legacy ATM/Frame Relay to modern SD-WAN architectures.

Officially released in Q1 2025, this build resolves 18 documented vulnerabilities while maintaining backward compatibility with ASR1000-ESP5/ESP10 modules scheduled for End-of-Support in 2026. The “ext” suffix indicates extended feature sets including NBAR2 protocol discovery and enhanced QoS policies for 40Gbps+ traffic loads.

Key Features and Improvements

​​1. Security Hardening​​

  • Patched control-plane DoS vulnerability (CVE-2024-XXXXX) affecting IPv6 neighbor discovery protocols
  • Enforced SHA-384 signatures for secure boot validation chains
  • TLS 1.3 default configuration for all management plane communications

​​2. Protocol Optimization​​

  • 40% faster BGP convergence through optimized UPDATE message processing
  • Enhanced EVPN/VXLAN scalability supporting 10,000 MAC entries per service instance
  • OSPFv3 stability improvements for dual-stack IPv4/IPv6 environments

​​3. Hardware Integration​​

  • Extended diagnostic tools for ASR1000-ESP20/ESP40 modules via enhanced show platform hardware outputs
  • Proactive memory leak detection for configurations using 32GB+ DRAM
  • Backward compatibility with legacy ASR1000-SIP10 interface processors until 2027

Compatibility and Requirements

Supported Hardware Minimum IOS XE Version Required Memory
ASR1000-RP1 (4GB DRAM) 03.10.05 8GB Flash
ASR1000-ESP20 03.11.01 16GB DRAM
