Hi, Doing some interop testing between two vendors we falled into misinterpretation of the current text of the End Of Sync marker content.
Here is the current text : "The end of synchronization marker is a PCRpt message with the SYNC Flag set to 0 for an LSP Object with PLSP-ID equal to the reserved value 0 (see Section 7.3). The LSP Object does not include the SYMBOLIC-PATH-NAME TLV in this case, it will include an empty ERO as its intended path and will not include the optional RRO object in the path. If the PCC has no state to synchronize, it will only send the end of synchronization marker." The current text, IMO, has the following issues : - it uses non normative wording : "does not include", "will include" , "will not include". How do we need to interpret it ? MUST, SHOULD, MAY ? - it does not precise if it can include or not some other objects : can it include an LSP-Identifier object (with all fields to 0) ? It would be good to enhance the text to better describe the content of EOS. We suppose that in case there is an issue with the encoding of the EOS marker, the following behavior will be applied, could you confirm ? (typically bad encoding of EOS marker) : " The PCE does not send positive acknowledgements for properly received synchronization messages. It MUST respond with a PCErr message with error-type 20 (LSP State Synchronization Error) and error-value 1 (indicating an error in processing the PCRpt) (see Section 8.5) if it encounters a problem with the LSP State Report it received from the PCC and it MUST terminate the session."
