The
reset
command warm-starts an SSP or IFP card, or the entire system. If
there is only one SSP or if you reset both SSPs, the default router software
image and configuration will be used. If there are two SSPs and you reset one,
the current router software image and configuration will be used. Issuing the
image and configuration will be used. If there are two SSPs and you reset one,

If you issue a

to the primary SSP in a system with a redundant
SSP, control will fail over to the secondary SSP, and the primary SSP will
