Hi Authors,

    I have a few of questions.

    Should a replication-segment be generalized to be a special SID (say a multicast SID allocated from a multicast SID block)?

    Should a replication-segment be associated with just a set of downstream SIDs without the  node-IDs? Where the downstream SIDs may be replication-segments or normal SIDs in some cases (for example when the downstream nodes are egresses).

    Should a state in a node for a replication-segment be removed? If a state is stored in a node (each node) for a (each) replication segment of a (each) SR P2MP path, there may be some scalability issue. This seems not consistent with the principles of the segment routing, in which no state is stored in the core of the network.

Best Regards,
Huaimo

    Hi SPRING WG,

    Authors of draft-voyer-spring-sr-replication-segment [1] have asked for WG adoption.

    Please indicate your support, comments, or objection, for adopting this draft as a working group item by July 6th 2020.

    Could those who are willing to work on this document, please notify the list. That gives us an indication of the energy level in the working group to work on this.

    As a reminder, the call for IPR has been done last November. [2]

    Thanks,
