Hi All, Kindly share your insights regarding the following query.
RFC 5440, section 7.8, states that "If no path satisfying the constraints could be found by the PCE, the METRIC objects MAY also be present in the PCRep message with the NO-PATH object to indicate the constraint metric that could be satisfied." However, I have encountered a scenario where the PCE sent a PCRep message with an Explicit Route Object (ERO), even when it could not locate a path meeting the constraints. Specifically, the Path Computation Client (PCC) sent a PCReq message with a Metric Object for "Hop Counts" set to "1" with the B flag enabled. Nevertheless, the PCE responded with a PCRep message containing an ERO object but with a different Metric Object "TE Metric". In such an instance, I wonder if it is appropriate for the PCC to send a PCErr message. If so, I would appreciate it if you could provide the appropriate Error-type and Error-value.
