GRP Boot Image Cisco IOS image that runs on the GRP when it is
booting from the network. This image is
essentially the same as the Cisco IOS image, but it
has large portions of the routing software
removed because it only acts as an IP host to boot
the router. It has all the same line card images and
microcode bundles as the Cisco IOS image.

Line Card Fabric
Downloader

loader that knows how to run the fabric only.
There is only one version of the downloader, and
it is bundled with the GRP Cisco IOS image.
