Software Packaging on the Cisco ASR 1000 Series Routers Software Packaging and Architecture 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 together creates a single consolidated package. A 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. Beginning in Cisco IOS XE Release 2.4, support for a supplemental, optional subpackage of type called 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 "Consolidated 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 package, supplemental optional subpackages, and other information 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. For information about the consolidated packages available in a specific version of Cisco IOS XE, see the release notes for that version of Cisco IOS XE. The Cisco IOS XE Software Release Notes contains the release notes for each version of Cisco IOS XE. 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.
