The RPIOS Cisco IOS XE subpackage is always different among consolidated packages. A consolidated package is an image that contains multiple subpackage files. Every consolidated package will contain the following subpackages:
- RPAccess -provides router access software, either with or without cryptologic support
- RPBase -provides the operating system software for the route processor
- RPControl -provides the control plane interface between the IOS software and the platform
- RPIOS -provides the IOS kernel, which stores and runs IOS software features
- ESPBase -provides the
- Embedded Service Processor (ESP) operating system and control processes
- SIPBase -controls the Session Initiation Protocol (SIP) operating system and control processes
- SIPSPA -provides the shared port adaptor (SPA) driver and field-programmable device (FPD) images
Of these subpackages, only the RPIOS subpackage is always different among consolidated packages. The RPBase, RPControl, ESPBase, SIPBase, and SIPSPA subpackages are always the same regardless of the consolidated package. There are two different versions of RPAccess: a K9 version, which includes cryptographic support, and a nonK9 version, which does not include cryptographic support.
Optional subpackages are also available. However, optional subpackages are not contained within consolidated packages; they must be downloaded directly from Cisco.
