:abbr:`RPKI (Resource Public Key Infrastructure)` is a framework :abbr:`PKI
(Public Key Infrastructure)` designed to secure the Internet routing
infrastructure. It associates BGP route announcements with the correct
originating :abbr:`ASN (Autonomus System Number)` which BGP routers can then
use to check each route against the corresponding :abbr:`ROA (Route Origin
Authorisation)` for validity. RPKI is described in :rfc:`6480`.

A BGP-speaking router like VyOS can retrieve ROA information from RPKI

validator") by using :abbr:`RTR (RPKI to Router)` protocol. There are several
open source implementations to choose from, such as NLNetLabs' Routinator_

First you will need to deploy an RPKI validator for your routers to use. The
RIPE NCC helpfully provide `some instructions`_ to get you started with
several different options. Once your server is running you can start

If you are responsible for the global addresses assigned to your
