In a Nutshell¶
RTRlib is a C library that implements the client side of the RPKI-RTR protocol as well as route origin validation. Basically, it maintains data from an RPKI cache server (e.g., Routinator) and allows to verify whether an autonomous system (AS) is the legitimate origin AS, based on the fetched valid ROA data. It is prepared for BGPsec path validation.
RTRlib powers RPKI in BGP software routers such as FRR and is the base for monitoring tools. A Python binding is available. The basis RTRlib package includes the library and lightweight command line tools.
Why do I need the RTRlib?¶
RTRlib gives easy and highly efficient access to cryptographically valid RPKI data without relying on a specific cache server or RPKI validator implementation. To prevent single point of failures, it handles failover between multiple cache servers.
Not only developers of routing software but also network operators benefit from RTRlib. Developers can integrate the RTRlib into their BGP daemon to extend their implementation towards RPKI. Network operators may use the RTRlib to develop monitoring tools (e.g., to evaluate the performance of caches or to validate BGP data).
