ROMMON is a low-level bootstrap code that initializes the router's hardware at power-on, facilitating the loading of the primary Cisco IOS XE operating system. The .pkg package file is used to upgrade ROMMON on an ASR1K router and is independent from the standard IOS XE software releases.

Note: Do not interrupt a ROMMON upgrade. It is a low-level flash operation; interrupting it can "brick" the Route Processor, requiring RMA.

In modern IOS-XE releases (like 17.x), ROMMON upgrades are often automatic when using the standard command. The system detects the ROMMON version in the consolidated package and updates it if necessary.

After completing the ROMMON upgrade, follow this checklist to ensure everything is functioning correctly:

The asr1000-rommon.173-1r.spa.pkg file is designed strictly for specific Route Processors within the ASR 1000 lineup. Do not attempt to load this package onto incompatible hardware, as doing so can cause the system to fail to boot. Supported Route Processors (Fixed configuration router) ASR1002-X (Fixed configuration router) ASR1001-HX and ASR1002-HX ASR1000-RP2 (Modular Route Processor 2) ASR1000-RP3 (Modular Route Processor 3)

Note: Always verify the exact hardware deployment using the show platform or show version command to ensure compliance with the 17.3(1r) release notes. Verification Check

Updates the bootloader (ROMMON) for various ASR components, including Route Processors (RPs), Embedded Services Processors (ESPs), and SPA Interface Processors (SIPs).

, as a failed ROMmon upgrade can render the router unbootable (requiring physical replacement of the RP).

ROMMON is the low-level bootstrap firmware embedded in the processor complex of an ASR 1000 Route Processor (RP) or Embedded Services Processor (ESP). It resides on a physical ROM chip and is the first code to execute when the router powers on.

Log into your device and verify your current hardware and running ROMMON version using the following command: Router# show platform Use code with caution.

ROMMON upgrade is . A failed upgrade (power loss during write, bad file, wrong hardware) leaves the RP in a non-bootable state. It is a low-level flash operation; interrupting it

Run the upgrade command targeting your primary Route Processor. For a standard single-RP system (like the ASR 1001-X), use:
