Hi Jamil,

Do you mean 2 images to boot the router from or redundant IOS process?

In first case you have to load both image on one of the router file systems and configure 2 "boot system" commands.

      boot system flash bootflash:file1.bin

      boot system flash bootflash:file2.bin

You can check for current config with "show boot" or "show run | i boot".

In case of standby IOS process, please see the following guide:

http://www.cisco.com/en/US/docs/routers/asr1000/configuration/guide/chassis/issu.html#wp1158739

In regards to ISSU - non-hardware-redundant chassis models (such as the  Cisco ASR 1001 Router, Cisco ASR 1002 Router and Cisco ASR 1004 Router)  do not support ISSU upgrade or downgrade. Instead subpackage software  upgrade is supported only if the router is running in subpackage  mode.Traffic loss cannot be avoided during the installation of the ESP  package as a part of ISSU.

Kind Regards,
Ivan

Ibrahim,

you got only 1 image " asr1000rp1-adventerprise.03.01.00.S-1.S.bin". If you want to add another one then you need to copy from tftp to the flash etc and change the boot order if you want the new IOS to be active as indicated by Ivan

Kishore is right.  There's only ONE (1) IOS there.  You can add a few IOS in there as long as the bootflash has enough space for them.
