Several router vendors participated in the development of the RPKI standards in the IETF, ensuring the technology offered an end-to-end solution for route origin validation. The RPKI to Router protocol (RPKI-RTR) is standardised in RFC 6810 (v0) and RFC 8210 (v1). Is it specifically designed to deliver validated prefix origin data to routers. This, as well as origin validation functionality, is currently available in on various hardware platforms and software solutions.
Various software solutions have support for origin validation:
In some solutions, such as OpenBGPD, RPKI-RTR is not available but the same result can be achieved through a static configuration. The router will periodically fetch the validated cache and allow operators to set up route maps based on the result. Relying party software such as Routinator and rpki-client can export validated data in a format that OpenBGPD can parse.
RTRlib is a C library that implements the client side of the RPKI-RTR protocol, as well as route origin validation. RTRlib powers RPKI in BGP software routers such as FRR. In a nutshell, it maintains data from RPKI relying party software and allows to verify whether an autonomous system (AS) is the legitimate origin AS, based on the fetched valid ROA data. BGP‑SRx by NIST is a prototype that can perform similar functions.
