  Running the Cisco ASR 1000 Series Routers: An Overview
A Cisco ASR 1000 Series Router configured to run using a consolidated package does have some 
advantages over a Cisco ASR 1000 Series Router configured to run individual subpackages. First, a 
consolidated package can be booted and utilized using TFTP or another network transport method. 
Secondly, configuring the router to use the one consolidated package file is easier than managing several 
individual subpackage files. Running the router using a consolidated package may be the right method 
of running the router in certain networking environments.
The consolidated package should be stored on bootflash:, usb[0-1]:, or a remote file system when this 
method is used to run the router.
Running the Cisco ASR 1000 Series Routers: A Summary
This section summarizes the advantages and disadvantages of each method of running your Cisco ASR 
1000 Series Routers.
The advantages of running your router using individual subpackages include:
Optimizes router memory usage—When the router is booting using the individual and optional 
subpackage method, software image content from the Router Processor (RP) is copied into memory 
on an as-needed basis only, which conserves memory for other router processes. The router boots 
fastest and allows for the highest peak traffic load when booted using the individual subpackage boot 
approach.
The advantages of running your router using a consolidated package include:
Simplified installation—Only one software file needs to be managed instead of several separate 
images.
Storage—A consolidated package, unlike individual subpackages, can be used to run the router 
while being stored in bootflash:, on a USB Flash disk, or on a network server. A consolidated 
package can be booted and utilized using TFTP or another network transport method, while the 
individual subpackage method requires the individual subpackage files to be copied into the 
bootflash: file directory on the router.
