Thanks for all the answers! I think I have one more detail I'd like to know.

Lets say you own X/22. You have delegated X/23 to your customer, keeping the other /23 for yourself. For some reason, your customer also owns and announced (to you) all remaining IPs necessary to complete X/21.

Do you announce the aggregate X/21 (including addresses not associated with you), the aggregate X/22 (only address belonging to you), or the more specific route X/23 (including only addresses delegated from you to your customer)?

Best regards,

Lars

Don't user as-sets step one.

Rpki does not understand how to express an as-sets' authorization.

Why do you want to do this?

Hi everyone,

how exactly do you aggregate routes? When do you add the AS_SET
attribute, when do you omit it? How does the latter interplay with RPKI?

Best regards,
