Configuration Tasks
Note On Cisco 10000 series devices, to boot both Performance Routing Engines (PREs) from the TFTP boot
server, you must enable DHCP on the PRE using the ip address negotiated command in interface
configuration mode. Otherwise, you will get a duplicate IP address error because of the synchronization
of the IP address from the active to the standby RP. Booting from the TFTP boot server is not supported
on other platforms.
This task describes how to set the boot image file and to modify the software configuration register boot
field so that the system boots the proper image.
