Technical Details

what runs on :323

RPKI-RTR is a TCP protocol between an RPKI cache server and a router, normally using TCP port 323. A router establishes a persistent session and exchanges framed protocol data units, using serial or reset queries to synchronize validated ROA data and cache state. The protocol supports incremental updates and full resets; RPKI-RTR over TLS is assigned to TCP port 324.

security overview

The base protocol is unencrypted and does not provide strong transport authentication, so access should normally be restricted to authorized routers with network ACLs or protected using the TLS variant or another secure tunnel. An exposed or compromised endpoint could cause resource exhaustion or deliver stale or manipulated validation data, potentially affecting route acceptance decisions.
