| RP Model | Supported ROMMON | Notes | |----------|----------------|-------| | RP1 (ASR1000-RP1) | Up to 152-1r | with 173-1r – different CPU architecture | | RP2 (ASR1000-RP2) | 173-1r and later | Fully compatible | | RP3 (ASR1000-RP3) | 173-1r baseline, but later versions exist | Works, but newer hardware may require 174+ | | ESP100/200/ESP3 | N/A | ESPs have separate firmware (not updated via this package) |
This post breaks down what this file is, why it is critical for your router's health, and how to verify it is running correctly. asr1000-rommon.173-1r.spa.pkg
asr1000-rommon.173-1r.spa.pkg is a small but mighty firmware package that enables modern IOS-XE releases on ASR 1000 RP2 platforms. It is not a routine upgrade, but a foundational step when moving to IOS-XE 17.3 or higher, adding hardware support, or patching critical boot-time vulnerabilities. Treat it with respect: test on a redundant RP, never interrupt the process, and always verify the new version after reload. | RP Model | Supported ROMMON | Notes
