Hello,
I've cisco ISR running:
Version 03.14.00.S
and rommon version Version 15.3(3r)S1
Now i want to update to latest recommended version: which is Everest 16.6.05.
So i've some questions: do i it's neccessary to update ROMMON also ? the documentation for 16.6 says, but not very clear:
"Table provides information about the recommended Rommon and CPLD versions for releases prior to Cisco IOS XE Everest 16.4.1. "
And it states: "Cisco 4451 ISR existis rommon: 16.7(4r)"
So do I understand correctly. That I can update IOS to latest recommended 16.6.05 and update ROMMON to latest one (isr4400_rommon_169_1r_SPA.pkg) which is newer than one mentioned in the table 16.7(4r).
Thank you

Thanks,
As I understood you say that updating to 16.4.1 would update the ROMMON itself. Thats nice, but how to know it by myself, because when reading documentation i dont see it stated:)
My second question is about:
IOS-XE 16.6.05 and ROMMON ver. 16.9 do this should work ? I never heard that newest Rommon could cause any problem with latest recommended IOS-XE. I would update both things and hope one reboot would be enough. What do you think ?
Thanks

Yes it varys from device to device whether just system flash bootflash: or system bootflash, the 4k routers series are all boot system flash bootflash: as you said
also good practice when its in the flash run this command first and verify the md5 hash is good so you know its not corrupt and isnt failing due to that , you can match it at the page where you downloaded the file , if you hover over the image you can see the value
verify /md5 bootflash:filename.bin

thank you,
Update worked only when I updated the ROMMON. Seems everything is OK now.
Anyway, i think that your suggested way to update to older version (which updates the rommon itself) and then update to new one is safer.
Thanks again
