RTRlib - The RPKI RTR Client C Library

The RTRlib is an open-source C implementation of the RPKI/Router Protocol client. The library allows to fetch and store validated prefix origin data from a RTR-cache and performs origin verification of prefixes. It supports different types of transport sessions (e.g., SSH, unprotected TCP) and is easily extendable.

The RTRlib is useful for developers of routing software but also for network operators. Developers can integrate the RTRlib into the BGP daemon to extend their implementation towards RPKI. Network operators may use the RTRlib to develop monitoring tools (e.g., to check the proper operation of caches or to evaluate their performance).
