Preparing the Standby RP
The following example clears the boot and TFTP filename environment variables, sets the EASYBAKE
variable to clean the hard disk, sets the configuration register to start up in Exec mode, and resets the
standby RP:
rommon B1> unset BOOT
rommon B1> unset TFTP_FILE
rommon B1> EASYBAKE=0x100000001
rommon B1> sync
rommon B1> confreg 0x2
rommon B1> reset
Step 5
boot disk1:/filename
Example:
rommon B1> boot disk1:/comp-hfr-mini.vm
Boots the file located on disk1: and installs it to the
default disk0:.
• This process removes any existing software
packages, resets the configuration register to
0x2, and boots the system.
• After the primary RP boots, the standby RP
downloads (synchronizes) the packages from
the primary RP and boots automatically.
• After the primary RP boots, the standby RP will
download (synchronize) the packages from the
primary RP and boot automatically.
• Allow the system to fully boot.
• If you chose the option to format disk0:, the
router enters Setup mode. The Setup mode
prompts allow you to enter the initial
configurations, as described in the “Entering the
Initial Configuration Using the Setup Mode
Prompts” section on page 4-5.
• If you chose the option to clean disk0:. The
system is fully booted when the CLI prompt is
shown and the interfaces are created.
