It could break if filters are based on announced prefixes. That's preciselly why uRPF is often useless. On the other hand, if a member provides transit, he will add its customer prefixes to RaDB / RIPEdb with appropriate route objects and the ACL will be updated accordingly. Shouldn't break there. -- Jérôme Nicolle +33 6 19 31 27 14
