Thanks. I actually wrote this in 2017 way before RFC9315, when I started getting involved building such software system at Google. I understand there has been some development the past few years. Never had chance to check how Apstra does thing, and here at Google we pretty much develop everything from ground up, even the modeling we use (UNM) is still not yet released to public
We have built a great product at Apstra, if anything has come close to a well designed/built INNS, Apstra would definitely be the closest one.
FYI - RFC9315 has a well written IBNS definition.
