Do not proceed if the output hash does not match Cisco’s website. Step 4: Execute the ROMMON Upgrade Command
Upgrading to asr1000-rommon.173-1r.spa.pkg is crucial for several reasons, particularly if you are upgrading your ASR1000 to IOS XE 17.x or higher.
An active console connection is required, as the upgrade will disrupt network management connectivity. asr1000-rommon.173-1r.spa.pkg
