Cisco 2851 Router

[DAVID RICHWALSKI]

I have a Cisco 2851 Router........I know it is End of Life

But can anyone tell me the latest IOS for it

This is what is currently on it.........

ROM: System Bootstrap, Version 12.4(13r)T11, RELEASE SOFTWARE (fc1)

System image file is "flash:c2800nm-advsecurityk9-mz.151-4.M10.bin"

Would it be c2800nm-adventerprisek9-mz.151-4.M4.bin  by chance?

Thank You for any help you can provide

Hi

The last ios is 

c2800nm-adventerprisek9-mz.151-4.M12a.bin

Please check this link:

Hope it is useful

Just to add to Julio's post.

I think you are reading your output incorrectly ie. you ask if 15.1.M4 is the latest but the IOS you are currently running is 15.1.M10.

Thumbs up!

Someone actually took the time to upgrade the ROMmon.  Good work!

15.1.4M12a was the last chronological release, and it's also Cisco's recommended release.

However, I wonder if it's the "latest" feature release.  There's also a chronological earlier 15.1.3T4 release.  Being a "T" release, I'm unsure whether 15.1.3T morphed into 15.1.4M or whether it should have morphed into (the non-existent, for a 2851) 15.2.4M.

Leo, Jon, Julio - your thoughts?
