Updates in the draft

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

Demo feedback

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]

Next steps

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.
