Even if a longer prefix like a /24 is announced, chances of people accepting it is slim. Especially, as you say, if the RIR allocation is something larger than /24 And I have a feeling acceptance /24 route announcements of anything other than legacy classful space, infrastructure space like the root servers is going to be patchy at best. 2008/12/19 Darryl Dunkin <ddunkin@netos.net>:
If you are allocated a /22, announce the /22. Do not announce anything longer unless you have a requirement to (such as a different origin AS). If you are further allocating a subset of that to a downstream, then a /24 out of that is acceptable as the origin will be different.
