  1. PCE-based Computation Procedure To Compute Shortest Constrained P2MP Inter-domain TE LSP. Quintin Zhao (quintin.zhao@huawei.com) Dhruv Dhody (dhruv.dhody@huawei.com) Zafar Ali (zali@cisco.com) Tarek Saad (tsaad@cisco.com) Siva Sivabalan (msiva@cisco.com) Daniel King (daniel@olddog.co.uk) Ramon Casellas (ramon.casellas@cttc.es) draft-ietf-pce-pcep-inter-domain-p2mp-procedures-01 82nd IETF @ Taipei

  2. Updates in the draft • New author Dhruv Dhody has joined this work. • Also provided implementation feedback. • Clarification of Core-Tree, Domain-Tree technique have been added along with updated figures. • Updates on - • Core-tree procedure for OF as SPT. • Domain-Sequence and PCE-Sequence • Protection mechanism • IANA • Editorial changes and readability 82nd IETF @ Taipei

  3. Demo Feedback • Implementation: • Computation of Core Tree • Grafting of Leaf nodes • Path Key for confidentiality • Current mechanism computes inter-domain P2MP LSPs as described in the document. • Identified for further discussion: • Domain Tree Representation as suggested in [DOMAIN-SEQ] • Domain Sequence encoding Per Destination [PER-DEST] 82nd IETF @ Taipei

  4. Next Steps • The authors request WG experts to review and comment. • The authors would like to see if other vendors have or are considering to implement. • The authors will stabilize the document and look to complete the work by IETF 83. 82nd IETF @ Taipei

  5. Questions & Comments? 82nd IETF @ Taipei

  6. Thanks! 82nd IETF @ Taipei
