Hi Martin Yes, we can assume that implementations will use RSVP-TE if they don't support this draft.
I think the text you quoted has fallen into the mistake of using normative language to specify what is already written in RFC 5440. Alvaro picked up another instance of this. How about we change to: If a PCEP speaker does not recognize the PATH-SETUP-TYPE-CAPABILITY TLV, it will ignore the TLV in accordance with [RFC5440]. and: If a PCEP speaker does not recognize the PATH-SETUP-TYPE TLV, it will ignore the TLV in accordance with [RFC5440], and will use RSVP-TE to set up the path. I have added a clarification to the second sentence above, as you requested.

I am fine with this but it does not say anything, explicitly, on what shall be the selected signalling protocol. I guess it will be RSVP-TE because I guess we treat this situation in the same way as if there had been no TLV. But since I am guessing, I feel it wouldn't hurt to be explicit. On the assumption that my guesses are correct, what about adding, for example, the following sentence (or anything else you'd judge more appropriate): From a signalling protocol selection point of view, this situation is treated as if the ... TLV was absent. _______________________________________________ Pce mailing list Pce@ietf.org https://www.ietf.org/mailman/listinfo/pce
