The Region2 field should show “APPROVED, preferred.” The ROMMON stored in the Region2 is now
the active ROMMON.
Storing More Than One ROMMON Image
The procedures in this section are optional and should be used only if you have multiple versions of the
upgraded ROMMON image stored on the RSP720.
There are three regions (including the Gold region) where versions of the ROMMON image can be
stored. You can use the upgrade rom-monitor slot preference and upgrade rom-monitor slot preference
commands to switch between regions.
The ROMMON software upgrade feature allows you to have two upgraded ROMMON images (one in
region F1, the second in region F2) in addition to the Gold ROMMON stored on the one-time
programmable (OTP) EPROM section of the ROMMON. Use the upgrade rom-monitor slot preference
command to select which ROMMON will be the preferred ROMMON the next time that the system is
booted. You can change the preference as often as you like. The changes do not take effect until you reset
the system.
To select a particular ROMMON image stored on the RSP720, perform this task:
Step 1 Change the ROMMON preference:
Router# show rom-monitor slot 5 sp
Region F1:FIRST_RUN
Region F2:FIRST_RUN, preferred

Router# upgrade rom-monitor slot 5 sp preference region1
