4. Interaction with Local Cache

Each BGP speaker supporting prefix validation as described in this document is expected to communicate with one or more RPKI caches, each of which stores a local copy of the global RPKI database. The protocol mechanisms used to gather and validate these data and present them to BGP speakers are described in [RFC6810].

The prefix-to-AS mappings used by the BGP speaker are expected to be updated over time. When a mapping is added or deleted, the implementation MUST re-validate any affected prefixes and run the BGP decision process if needed. An "affected prefix" is any prefix that was matched by a deleted or updated mapping, or could be matched by an added or updated mapping.
