Chapter 1 Software Packaging and Architecture
Software Packaging on the Cisco ASR 1000 Series Routers
information on the advantages and disadvantages of running a complete consolidated package, see
the
“Running the Cisco ASR 1000 Series Routers: An Overview” section on page 3-1
. For additional
information on provisioning files, see the
“Provisioning Files” section on page 1-4

If you need to install optional subpackages, then you must boot the router using the individual
subpackage provisioning file method.
Individual Software SubPackages Within a Consolidated Package
provides an overview of the Cisco ASR 1000 Series Routers subpackages and the purpose of each
individual subpackage. Every consolidated package will have all of these individual subpackages. To see
additional information about each individual subpackages in a particular Cisco IOS XE release, see
Cisco IOS XE Release Notes
for that release.
Important Notes About Individual SubPackages
The important information about individual subpackage include:
•
Individual subpackages cannot be downloaded from Cisco.com individually. To get these individual
subpackages, users must download a consolidated package and then extract the individual
subpackages from the consolidated package using the command-line interface.
•
If the router is being run using individual subpackages instead of being run using a complete
consolidated package, the router must be booted using a provisioning file. A provisioning file is
included in all consolidated packages and is extracted from the image along with the individual
subpackages whenever individual subpackages are extracted. For additional information on
provisioning files, see the
“Provisioning Files” section on page 1-4
.
