Hello Jeker, I am "announcing al" already. Please enlighten ment, when I do a bgpctl sh rib out nei <description> The prefixes I see are the ones the peer *accepted* from me or the ones I am actually announcing, no matter if the peer accepts or not? Because I "announce all" and later, filter by community, and the abouve "sh rib out nei <d>" shows empty.
