Setting the Config-Register Boot Variable
Though it is not required, we recommend that you modify the software configuration register boot field
so that the system boots the same image that the hw-module slot slot-number image file-spec command
specifies in the “Configuring RPR and RPR+” section on page 43.
Configuring RPR and RPR+
Each task in the list is identified as either required or optional.
• Configuring RPR and RPR+, page 43 (required)
• Verifying RPR and RPR+, page 44 (optional)
• Configuring RPR and RPR+ Example, page 45 (optional)
Note Online removal of the active RSP causes all line cards to reset and reload, which is the equivalent to an
RPR switchover, and results in a longer switchover time. When it is necessary to remove the active RSP
from the system, first issue a switchover command to switch from the active RSP to the standby RSP.
