Hello Jorge,

Boot helper is a small image with few functions used to find and load the main fully functional IOS image. It is stored in internal flash memory (the boot helper image comes installed on the NPE-G2).

It is usually recommended to have matching versions of the boot helper image and IOS image, so I suggest to upgrade both.

Note that NPE-G2 images start with the prefix "c7200p-" in the software images filenames, including the boot image.

The NPE-G2 does not boot up with a software image with the prefix "c7200-". Previous network processing engines, or the network services engine, do not boot up with the "c7200p-" boot image. They use the prefix "c7200-".

Kind Regards,
Ivan Shirshin
