6. Software installation, PIE packages,

and patches

As part of any system, from time to time you need to install updates,

patches, and upgrade code. The joys of IOS XR code is that you can actually

installed patches that fix bugs, you can perform in-service upgrades and not

take down the router (provided you have a dual-supervisor router), as well as

add new services to the code. All the necessary PIE packages can be found in

the main image, they are not available separately.

You can get the main image from CCO Support and Downloads. To navigate to

the download, select:

Products -> Routers -> Service Provider Edge Routers -> ASR 9000 -> ASR 9006

Then select IOS XR Software for the main images or IOS XR Software

Maintenance Upgrades (SMU) for patches for caveats fixes.

Once you select the IOS XR Software, the most recent version of code will be

presented on the screen. Select the version that you need and proceed to

download it. If you get an error that a contract is required, please open a

Cisco TAC case requesting access, they will need the serial number of the

chassis in order to prove support.

Once you have the image on your computer, we will now need to transfer it.

Since the image is over 400 Megs as of 4.1.2, and 4.2.0 is over 700 Megs,

TFTP is probably not going to cut it (most TFTP apps do not support files

over 32 megs). What you might need to do is find an FTP server program to

use - I recommend FileZilla – but that is ultimately up to you. Once you

have your FTP server setup and ready to go, we now need to get the image

copied. For this example, I am using a username of Cisco and a password of
