A peer's configured role now does three more things: - Our OPEN carries the BGP Role capability with what we are to the peer. A peer whose own says it is something that does not pair with that, or that sends two different roles, is refused with OPEN Message Error / Role Mismatch. A peer that says nothing is accepted unless require_role is set. A role on a peer in our own AS is a configuration error. - Routes from a provider, a peer or a route server are marked Only to Customer on the way in if they are not already, and our routes are marked on the way out to a customer, a peer or a route server client. - A marked route from a customer or route server client, or from a peer with someone else's mark, is a leak and is refused. No policy setting turns that off. The packet crate gains the Only to Customer attribute (malformed: treat-as-withdraw), and the Role Mismatch subcode is corrected from 8 to 11. The status page shows whether the peer confirmed its role. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
