Repeating my previous review - this is not needed. We added the level-from leaf to the redistribute container, specifically to cover all of this. Why do you think this separate container is needed?

The common practice in YANG models is to use dashes (-), not underlines (_). Please, change this to level-from.

Regardless of the necessity of route_leaking container, this is not needed because it's a complete copy of grouping redistribute-attributes.

As in my previous review - there are no such levels in IS-IS and this change is wrong and unnecessary. That's exactly why we have two leafs - level and level-from.
