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
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.

Software Packaging on the Cisco ASR 1000 Series Routers
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 2.
A collection of software subpackages packaged togethe
consolidated package allows users to upgrade all individual subpackages on the router with a single
software image download. Consolidated packages can be downloaded from Cisco.com; users who want
to run the router using individual subpackages that are part of the consolidated package must first
download the image from Cisco.com and extract the individual subpackages from the image, which can
be done by entering request platform command-line interface commands.
Software Packaging and Architecture

Beginning in Cisco IOS XE Release 2.4, support for a s
sipspawma is introduced to support the Cisco WebEx Node for ASR 1000 Series shared port adapter
(SPA). Optional subpackages are installed similarly to individual subpackages; however, optional
subpackages are not bundled as part of a consolidated package like prior support for the individual
subpackages, and optional subpackages must be downloaded independently.
See the “C
onsolidated Packages” section on page 2 and “Individual Software SubPackages Within a
Consolidated Package” section on page 3 of this book for additional information on extracting individual
subpackages from a consolidated pa
on managing software.
Consolidated Packages
A consolidated package is a single image composed of individual software subpackage files. A single
consolidated package file is a bootable file, and the Cisco ASR 1000 Series Router can be run using the
consolidated package.
Note Consolidated packages only contain the required individual subpackage files. These packages do not
contain supplemental, optional subpackages, such as the “sipspawma” package for the Cisco WebEx
Node for ASR 1000 Series.
Each consolidated package also contains a provisioning file. A provisioning file is used for booting in
cases where the individual subpackages are extracted from the consolidated package, or optional
subpackages are used to run the router. For additional 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 1. For additional information on provisioning files, see the “Provisioning
Files” section on page 4.

ckage, supplemental optional subpackages, and other information
Important Information About Consolidated Packages
The important information about consolidated packages include:
• For each version of a consolidated package, the RPBase, RPControl, ESPBase, SIPSPA, and
SIPBase subpackages are identical among consolidated packages.
• For each version of consolidated package, the RPIOS subpackage is always different among
consolidated packages.

consolidated package, boot the router using the consolidated package file. If the router is configured
to run using individual subpackages, boot the router using the provisioning file. For additional
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 1. For additional
information on provisioning files, see the “Provisioning Files” section on page 4.
• If you need to install optional subpackages, then you must boot the router using the individual
subpackage provisioning file method.

• 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 4.

Optional Software SubPackages Outside of Consolidated Packages
Beginning in Cisco IOS XE Release 2.4, the ASR 1000 Series Routers support a new type of
subpackage—this is an optional software subpackage that is available as a separate, external package
that is downloaded and installed along with the other required subpackages.
sipspawmak9 is an optional subpackage that provides
for ASR 1000 Series Routers.
Important Notes About Optional SubPackages
The important information about optional subpackages include:
• Optional subpackages are downloaded separately from consolidated package files. Optional
subpackages are not contained within a consolidated package for a release.
• Optional package installation works similarly to the installation of individual subpackages using a
provisioning file.
• Optional subpackages can be uninstalled to remove provisioning when the package no longer
applies to an RP.
• Optional subpackages are easily supported by the standard ISSU upgrade process as long as the
package is located in the directory of the provisioning file for each RP.
Provisioning Files
Note You must use the provisioning files to manage the boot process if you need to install optional
subpackages.
the system software for the Cisco WebEx Node
Provisioning files manage the boot process when the Cisco ASR 1000 Series Router is configured to run
using individual subpackages or optional subpackages (such as the package for the Cisco WebEx Node
for ASR 1000 Series). When individual subpackages are being used to run the Cisco ASR 1000 Series
Router, the router has to be configured to boot the provisioning file. The provisioning file manages the
bootup of each individual subpackage and the Cisco ASR 1000 Series Router assumes normal operation.

Important Notes About Provisioning Files
The important information about provisioning files include:
• Each consolidated package contains two provisioning files. One of the provisioning files is always
named “packages.conf”, while the other provisioning file will have a name based on the
consolidated package naming structure. In any consolidated package, both provisioning files
perform the exact same function.
• In most cases, the “packages.conf” provisioning file should be used to boot the router. Configuring
the router to boot using this file is generally easier because the router can be configured to boot using
“packages.conf”, so no changes have to be made to the boot statement when Cisco IOS XE is
upgraded (the boot system file-system:packages.conf configuration command can remain
unmodified before and after an upgrade).
• The provisioning file and individual subpackage files must be kept in the same directory. The
provisioning file does not work properly if the individual subpackage files are in other directories.
• The provisioning filename can be renamed; the individual subpackage filenames cannot be renamed.
• After placing the provisioning file and the individual subpackage files in a directory and booting the
router, it is highly advisable not to rename, delete, or alter any of these files. Renaming, deleting, or
altering the files can lead to unpredictable router problems and behaviors.

File to Upgrade Field Programmable Hardware Devices
Starting in Cisco IOS XE Release 3.1.0S, a hardware programmable package file used to upgrade field
programmable hardware devices is released as needed. A package file is provided for the field
programmable device to customers in cases where a field upgrade is required. If the Cisco ASR 1000
Series Router contains an incompatible version of the hardware programmable firmware on the Cisco
ASR1000-RP, Cisco ASR1000-SIP, or Cisco ASR1000-ESP, then that firmware may need to be
upgraded.

Processes Overview
Processes Overview
Cisco IOS XE has numerous components that run entirely as separate processes on the Cisco ASR 1000
Series Routers. This modular architecture increases network resiliency by distributing operating
responsibility among separate processes rather than relying on Cisco IOS software for all operations.

• IOS as a Process, page 7
• Dual IOS Processes, page 8
