IOS vs IOS-XR features

As I am building new tasks for this workbook, I encounter features that are present in the IOS, but not implemented (yet?) in IOS-XR (or vice versa).
I could not find any available resource that provides such differences list, so I decided to keep my own.
This Cisco tool can be used to check the different features support across devices and Cisco operating systems.


In this post I will keep track of such features.

  1. Hi Dmitry,

    First of all thanks for your blog.

    You can take a look at the Cisco command transition documentations: http://www.cisco.com/c/en/us/td/docs/ios_xr_sw/iosxr_r3-5/xr12000_conversion/reference/guide/cnv_r35/cn35main.pdf
    I assume it can help you a lot.

    BR,
    Anton
