Dear All The following text is taken from draft-ietf-pce-pcep-16.txt >> In the case of the reoptimization of a TE LSP, the bandwidth of the existing TE LSP MUST also be included in addition to the requested bandwidth if and only if the two values differ. I'm want to understand the negative meaning and PCE behavior in the following case. PCC is sending a PCReq message for reoptimization of a TE LSP and there is no bandwidth case. But PCC is sending PCReq with Existing and Requested bandwidth (containing same value in this case). Is this an error (PCE should drop the Request and send a PCERR or PCE can just ignore as the values are same. Please clarify. Best regards S.SenthilKumar 7.7. BANDWIDTH Object The BANDWIDTH object is used to specify the requested bandwidth for a TE LSP. The notion of bandwidth is similar to the one used for RSVP signaling in [RFC2205], [RFC3209] and [RFC3473]. If the requested bandwidth is equal to 0, the BANDWIDTH object is optional. Conversely, if the requested bandwidth is non equal to 0, the PCReq message MUST contain a BANDWIDTH object. In the case of the reoptimization of a TE LSP, the bandwidth of the existing TE LSP MUST also be included in addition to the requested bandwidth if and only if the two values differ. Consequently, two Object-Type values are defined that refer to the requested bandwidth and the bandwidth of the TE LSP for which a reoptimization is being performed.
