Software Packaging and Architecture Software Packaging on the Cisco ASR 1000 Series Routers • A consolidated package file is a bootable file. If the router is configured to run using a the complete 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. 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. Table 1 Individual SubPackages SubPackage RPBase RPControl RPAccess RPIOS ESPBase SIPBase SIPSPA Purpose Provides the operating system software for the Route Processor. Controls the control plane processes that interface between the IOS process and the rest of the platform. Exports processing of restricted components, such as Secure Socket Layer (SSL), Secure Shell (SSH), and other security features. Provides the Cisco IOS kernel, which is where IOS features are stored and run. Each consolidated package has a different RPIOS. Provides the ESP operating system and control processes, and the ESP software. Controls the SIP operating system and control processes. Provides the SPA driver and Field Programmable Device (FPD) images. 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 4. Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide 3
