Hi, We have just submitted the second revision of our I-D,draft-chen-ccamp-ospf-interas-te-extensions. The problem we are trying to solve is how a PCE or entry-point ASBR can select the exit-point ASBR for a TE LSP when it knows (from the ERO) the downstream AS or the downstream ASBR. We believe that IGP needs to flood the inter-AS TE links together with additional information about the neighboring AS and ASBR. The problem arises for both the pd-path and brpc computation methods. We would welcome your input on our problem statement and our proposed solution.
