A PCEP speaker receiving any other message apart from StartTLS, Open, or PCErr as the first message, MUST treat it as an unexpected message and reply with a PCErr message with Error-Type set to [TBA2 by IANA] (PCEP StartTLS failure) and Error-value set to 2 (reception of any other message apart from StartTLS, Open, or PCErr message), and MUST close the TCP connection. According to RFC5440, when a non-Open message is received the PCEP speaker is required to send a PCErr message with Error-Type 1 ("PCEP session establishment failure") and Error-value 1 ("reception of an invalid Open message or a non Open message"). I think this text needs to be reworded to narrow down the scope of this error. * The fallback procedure after receiving the error code 4 needs to be clarified. Is the response 4 remembered for future connections or is it only limited to a single attempt immediately after the TLS connection establishment failure. i.e. After falling back, does the client ever try to establish a secure connection again? ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- * Section 3.2: This sentence needs to be reworded s/If a PCE that supports PCEPS connection/If a PCE supports PCEPS connection/ _______________________________________________ Pce mailing list [email protected] https://www.ietf.org/mailman/listinfo/pce
