Hello. Unfortunately, I'm not so experienced in the question to anwer that. Therefore I ask for help and will be thankful for any clarification.
We have a /20 ASSIGNED PI address block and an AS. Is it allowed by RIPE policy to intentionally announce more specific prefix than one we have from our AS to upstream ASes? For example, announce our X.X.0.0/20 to upstream A and announce both X.X.0.0/20 and X.X.6.0/23 to B?
It is not disallowed. What's more - it is common practice to perform incoming capacity engineering in this way.
But, IMHO, preferably in a multiple interconnection to a single AS scenario only (having that AS export the shortest prefix only). Mh
