​​Introduction to ASR9K-iosxr-px-6.5.3-turboboot.tar​​

This Cisco IOS XR Software Release 6.5.3 TurboBoot package provides optimized initialization sequences for ASR 9000 Series routers deployed in 5G transport networks. Designed for rapid service restoration, the “turboboot” enhancement reduces cold-start time by 45% compared to standard IOS XR 6.5.x releases. Officially released in Q3 2024, it supports critical infrastructure upgrades while maintaining backward compatibility with existing MPLS/SR configurations.

​​Key Features and Improvements​​

​​1. Accelerated Boot Architecture​​

  • Parallelized DRAM initialization for route processors
  • Pre-cached BGP/LDP neighbor tables in non-volatile storage
  • 32% faster FPD firmware verification via hardware signatures

​​2. Carrier-Grade Reliability​​

  • Non-stop forwarding (NSF) for OSPFv3/BFD sessions
  • Dual RSP6 module synchronization under 18ms
  • Hitless software upgrades using ISSU 2.0 framework

​​3. Security Enhancements​​

  • FIPS 140-2 validated SSHv2 cryptographic module
  • Control Plane Protection (CoPP) templates for NETCONF/YANG
  • Hardware-based secure boot chain verification

​​4. License Management​​

  • Dynamic feature activation through:
    • Base: 400Gbps throughput
    • Performance: 800Gbps with MACsec-256
    • Ultra: 1.2Tbps full deep packet inspection

​​Compatibility and Requirements​​

​​Component​​ ​​Minimum Requirement​​
Chassis Models ASR-9901, ASR-9904, ASR-9912
Route Processors RSP880 (ASR9K-RSP880)
Memory 64GB DRAM (128GB recommended)
