​​Introduction to asr9k-mini-x64-migrate_to_eXR.7.1.2.tar Software​​

The ​​asr9k-mini-x64-migrate_to_eXR.7.1.2.tar​​ is a specialized migration package for Cisco ASR 9000 Series routers transitioning to IOS XR Everest 7.1.x. Designed to streamline upgrades from legacy IOS XR 6.x/5.x deployments, this toolset preserves configurations while implementing RFC 8368-compliant segment routing optimizations.

Released in Q3 2024, it supports ASR 9922, ASR 9910, and ASR 9906 chassis with RSP880/RSP880-LT route processors. The package includes automated validation scripts to minimize downtime during critical infrastructure modernization projects, particularly for service providers adopting SRv6 and 400G interfaces.

​​Key Features and Improvements​​

  1. ​​Seamless Configuration Conversion​​

    • Converts legacy MPLS-TE configurations to SRv6 policies with 98% accuracy using embedded xr6_to_everest.py parser.
    • Preserves QoS markings during migration via DSCP-to-TC/TC-to-EXP mapping tables.

  2. ​​Security Compliance​​

    • Implements FIPS 140-3 validated encryption for OSPFv3 and BGP-LS control-plane communications.
    • Migrates RADIUS/TACACS+ shared secrets using AES-256-GCM cryptographic wrapping.

  3. ​​Performance Validation​​

    • Includes precheck_migration utility to verify 400G interface readiness (minimum 64GB DRAM per line card).
    • Generates comparative throughput reports for pre/post-migration SRv6 traffic flows.

  4. ​​Automation Enhancements​​

    • Exports NETCONF/YANG models compatible with Cisco Crosswork 3.3+ for zero-touch provisioning.
    • Provides Ansible playbooks for bulk migration of 50+ routers in leaf-spine architectures.
