Hi Dino, 

Thank you for the follow-up and the new revision draft-ietf-lisp-geo-15.

[Med] I don't see this addressed in draft-ietf-lisp-geo-15.

[Med] ACK. What about consistency with RFC9179?

[Med] I understand that was the deal at that time but these efforts were 
abandoned.

[Med] My concern is more about this claim:
