Dear JP, There maybe several inter-AS links between two adjacent ASes, so we just selected some of them that can satisfy the constraints in both of the directions. Of cause, if all of the inter-as links can not satisfy the constraints, PCE will stop relying as you say,and will reply an PCRep message including a NO-PATH object. Thanks for your questions Xuerong

Quick question: when relaying the PCReq, why not simply check the TED in the reverse direction and stop relying if constraints are not satisfied ? Thanks. JP.

I think it is important to get bidirectional Inter-AS TE link information for inter-AS path computation. If you are interested in this topic, hope you can have a look and review this draft.
