Software Packaging on the Router
Software Package Modes
The router can be booted using any of the following:
-
Consolidated—A single software image containing a full collection of software packages. This mode provides a simplified installation and can be stored in the bootflash, a TFTP server, or a network server.
-
Sub-package—One or more sub-images that are extracted from the consolidated image. This mode provides optimized memory usage and requires that you store files in the bootflash directory.
Note |
The Install Workflow based ISSU method is supported on the Cisco RSP3 module from Cisco IOS XE release 17.3.1. Also, the legacy ISSU method of using request platform software method is still supported. |
