The configuration register setting is a 16-bit, user-configurable value that determines how the route
processor (RP) functions during initialization. The configuration register can cause the RP to boot
normally from the default configuration, or to enter ROMMON mode during a reload. Configuration
register settings can also be used to perform tasks such as password recovery.

Modification
This command was introduced on the Cisco ASR 14000 Series Router.
config-register command is entered in administration EXEC mode, on the designated system
config-register command, note the following conditions:
If both the primary and standby DSC are up and running when the configuration register value is set,
the configuration register value applies to both the primary and standby DSC.
By contrast, if only the primary DSC is up and running when the configuration register value is set
and the standby DSC is introduced into the router at a later time, the router does not attempt to
synchronize the configuration register value for the standby RP to that of the active RP; in this
situation, the configuration register setting applied to the standby DSC is determined by the
configuration register value set in ROMMON mode.
Hexadecimal or decimal value that represents the 16-bit configuration
register value to be used the next time the router is reloaded. Range is
from 0x0 to 0xFFFF (0 to 65535 in decimal).
