How to bring up RP on XR12000 router if no XR image available on disk

This effort involve two main steps on router as well as external resource, like: XR image is availabe on external tftp server and should be accessibe   by this router.

Mainly we need perform  router pre-configuration in boothelper mode, and load image from tftp server and bootup from ROMMON mode.

Step 1

bring RP to boothelper mode, and perform router pre-configuration.

note: you can not bring only standby RP to boothelper while active RP is XR RUN. you have to bring dowm whole router to ROMMON first.

If router has no image, it will be in rommon mode first. Then just enter "boot" command to take RP to boothelper.

rommon 1 > boot

pre-configuration in boothelper.

Router(boot)>enable

Router(boot)#config t

Router(boot)#(config-interf)interface ether 0

Router(boot)#(config-interf)ip add x.x.x.x x.x.x.x

Router(boot)#(config-interf)no shu

Router(boot)#(config)ip default gateway x.x.x.x

Router(boot)#(config)write memory

Router(boot)#(config)config Regis 0x0

Router(boot)#ping 223.255.254.254         (e.g.  223.255.254.254 is location of XR image on tftp server, confirm it is accessable)

Router(boot)#reload   (bring RP into ROMMON mode from boothelper status)

step 2

In ROMMON, we need set proper ROMMON variables then load image from tftp server and bootup.
