ASR 1000 Series Routers Software Overview
The Cisco ASR 1000 Series Routers run using Cisco IOS XE software. Cisco IOS XE is released using
consolidated packages and optional subpackages.
Each consolidated package contains a collection of software subpackages. Each software subpackage is
an individual software file that controls a different element or elements of the Cisco ASR 1000 Series
Router. Each individual software subpackage can be upgraded individually, or all software subpackages
for a specific consolidated package can be upgraded as part of a complete consolidated package upgrade.
Importantly, IOS (the RPIOS subpackage) is considered one of the seven individual subpackages that
makes up a complete consolidated package. For additional information on individual software
subpackages, see the
“Consolidated Packages” section on page 1-2
.
