Hi,
I have a problem with a 2811 Route similar to the one described here: https://community.cisco.com/t5/switching/cisco-2851-router-rebooted-automatically/td-p/3353992
Due to the continuous and unexpected reboots, I have to update the IOS of this device as the best solution.
The current IOS is shown as follows:
c2800nm-advipservicesk9-mz.124-9.T3.bin
And the current hardware features are: 256 MB RAM, 64 MB Flash.
As I have seen, the T (Train) version could cause problems, and Cisco recommends the M version. Besides, the 12.4 is a deferred realease, so Cisco suggests 15.1.4M12aMD
The upgrade path would be then from c2800nm-advipservicesk9-mz.124-9.T3.bin to c2800nm-advipservicesk9-mz.151-4.M12a.bin. However, the requirements are a 512 MB RAM and a 128 MB Flash memories, which don't match with the features of this device.
Which could be the best IOS version in order to complete the update and solve this issue?
Thank you so much.
David
