Asr1000-rommon.173-1r.spa.pkg

Early ASR 1000 units had 4GB bootflash. Modern IOS XE images easily exceed 1GB, and 173-1r improved the ROMMON’s file system driver to handle 8GB, 16GB, and even 32GB USB drives for recovery.

The jump to 173-1r was not minor. Previous ROMMON versions (like 16.x or 122-8r) lacked critical support for modern boot scenarios. Here is what 173-1r introduced or fixed: asr1000-rommon.173-1r.spa.pkg
