Yes, but in that scenario any advertisements between /32 and /36 from that prefix originated by AS65500 are *valid* . That's why "ROAs should be as precise as possible, meaning they should match prefixes as announced in BGP" [1]
You completely ignored my statement of the need for appropriate AS-0 ROAs to block those.
I did not want to comment because you can go down that path *and* you will assume everyone doing ROV will consider AS0 ROAs as well. IMHO the bare minimum is to cover your advertisements with a ROA as precise as possible. -- Willy Manga @ongolaboy https://ongola.blogspot.com/
