Hi Frederick, In the current operation of TE OSPF, the LSRs at each end of a TE link emit LSAs describing the link.The databases in the LSRs then have two entries (one locally generated, the other from the peer)that describe the different 'directions' of the link. For the inter-AS link, there i

Hi all, A new version of draft-wang-pce-inter-as-extentions (version -01) was published. (http://tools.ietf.org/html/draft-wang-pce-inter-as-extentions-01) The changes in this version focus on the requirements that why we need to extend BRPC and PCEP in the case of computing inter-as bi-d

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

Dear JP, Thanks for your good question, and we'll consider this in the next version. For the scenarios that there are serveral Inter-AS links between two ASes, if all of them do not satisfy the constraints, PCE will return PCRep with NOTH-PATH object, and the PCReq will not be relayed. Howev

Dear all, We have uploaded a draft, which is about extensions of Backward-Recursive PCE-Based Computation (BRPC) to support bidirectional inter-AS LSP path computation. I think it is important to get bidirectional Inter-AS TE link information for inter-AS path computation. If you are
