Is the config snippit you're interested in still in the startup-config, or 
one of the saved configs on the box.  Do you have backups of the original 
configuration?  I don't have any direct experience with IOS-XR at the 
moment, so I'm not sure if the syntax for what you want to do varies 
significantly from IOS or NX-OS.
