Zhenbin, Cheng, and Nan, Section 3.2 of the draft-li-spring-tunnel-segment-02 discusses the SR traffic traversing non-SR domains. Do you require a Tunnel Segment that connects 2 (or more) SR islands to be preestablished? Can the Tunnel segment be IPsec Tunnel? So that two separate SR islands can be connected by the third party network (e.g., Internet)? Are the two SR islands under the same administrative control? i.e., Are the SID used by SR Island-1 recognized by nodes within the SR Island-2 ? Thank you. Linda Dunbar
