Hi, In Section 5.6 raises an obvious issue : the presence of additional vendor-specific information in PCEP messages may congest the operation of the protocol especially if the PCE does not support the constraints supplied by the PCC.
Would it be safer to propose that the proposed feature should only be used for inter-area and inter-layer path computations (and not for inter-domain)?! I dont really see the prospect of using vendor specific constraints in an inter-domain environment...
