I have a few Cisco 831's that I am trying to upgrade the memory on. Most of them have the ROMMON version 12.2(11r)YV3. I have no issues upgrading the memory on these models.
Then there are some with ROMMON version 12.2(8r)YN which is giving me nightmares.
My question is how do I upgrade ROMMON? Where can I find the new ROMMON version?
You obviously need privileges to download IOS and other software from CCO, however the link to ROMMON for the 83x series routers is here:
Latest release is 122-11r.YV6
