On a router with redundant SRP modules, you can specify the configuration that both
the primary and redundant modules load in the event of a reload or switchover. A
switchover can result from an error on the primary SRP module or from an srp switch
command. The following behavior takes place only in the event of a cold restart; it does
not take place in the event of a warm restart.
When you arm a configuration (.cnf) file by issuing the boot config cnfFilename command,
a subsequent SRP switchover causes the redundant SRP module to take the role of
primary SRP module with the configuration specified by the .cnf file. The new primary
SRP module does not use the running configuration.
