CRS-1 IOS XR Upgrade

Hi,

Anybody have alredy work with a CRS-1? I would like to understand the procedures to install and upgrade IOS XR. It's a new device to be installed in a service provider to replace a GSR Router. The documents I search, I noticed that there's a big difference compare to the normal IOS and more difficult to understand the concepts.

Thanks.

Re: CRS-1 IOS XR Upgrade

Hello Paulo,

I agree that is quite different from classic IOS.

In IOS XR you can have a full upgrade or the installation of patches called SMU.

Similarly to unix or linux operating systems the process can be described as:

copying to file system the installation files in appropriate path

installation of packages

activation of the packages

there is no single image in IOS XR.

a good starting point can be

or

Be prepared for some issues when connecting to other IOS based devices there are some default settings that are different.
