Dear PCE'ers I reviewed the document and I have the following comments/questions:
1) The document implies that the PCC has to /MUST do IP address to SID conversion, I think that it would allow a more simpler PCC if that capability is optional and negotiated with additional error codes to indicate that the NAI SR-EROs are not supported. 2) One aspect of the SR-ERO processing is that, when building the label stack, the PCC should have enough information to decide on the outgoing link (this can be provided by the PCE). It will be good if the document state could spell out this part of the procedure and indicates any specific SR-ERO procedure. For instance one solution could be that the PCE may use IP address or Adjacency SID to indicate the outgoing link. 3) Taking the outgoing link selection into account, the Maximum Stack Depth (MSD) calculation may be not trivial: for instance if the first hop is a local Adjacency-SID, then the label will not be stacked, but it will if the first hop is a Prefix SID it may be counted (non-adjacent node or adjacent node without PHP) but it may not be counted (adjacent node, with PHP). I think the draft should clarify it. Thanks, Cyril
