(Changing the subject to avoid confusion with all other "slot requests")
I agree with Acee that there are existing solutions for this problem space.
I also believe your approach is quite problematic.
To maintain the count ("TTR") accurately, you would require full deployment of
this extension - partial deployment would not be viable.
Also, you are proposing changes to route preference, which means you are
altering the IS-IS Route Preference rules as defined in RFC 7775/RFC5302. With
partial deployment, we would be at risk for loops as some nodes would be
operating on existing preference rules and some nodes would be operating on
revised preference rules.
Given these issues and the fact that there is no compelling need for a new
solution, I do not see a future for this draft - or its predecessor
draft-yue-lsr-loop-detection-for-imported-routes.
