Hi Ytti,

>> Pushing thousands of lines via CLI/expect automation is def not a great idea, no. Putting everything into a file, copying that to the device, and loading from there is generally best regardless. The slowness you refer to is almost certainly just because of how XR handles config application. If I'm following correctly, that seems to be the crux of your question.

Perfect answer :)

Not what I was hoping to hear, but if that’s what it is, then that’s what it is.
