As far as I see it, access lists are doing literal matching.

docs.frrouting.org/en/stable-7.0/filter.html

E.g. 10.0.0.0/30 != 10.0.0.0/24

Using
	access-list not-ptp deny 10.0.0.0/24
	access-list not-ptp permit any

Only 10.0.0.0/24 would be denied. Any prefixes larger or smaller will be
permitted, matching the permit any statement coming after.

The current documentation is your best option. Including the examples.
docs.frrouting.org (The official documentation is in no way all glorious
110 % perfect. But is your best starting point)

Otherwise you are down to blog posts, mailing list threads, forum posts,
GitHub issue threads, etc. (i.e. whatever else you can find)
