Hi Bruno, I believe the description and usage of Locator is very well described and covered in the net-pgm draft as also the corresponding IGP extensions. Is the question is more about the “block” part of it (what is not in the block part is in the node part as per the text in the net-pgm draft)?
The “block” is again not a new thing. Please check the following: Under https://tools.ietf.org/html/draft-ietf-6man-segment-routing-header-26#section-5 … look for “block” https://tools.ietf.org/html/rfc8402#section-2 … look under SRGB for SRv6 So perhaps I don’t get Chris’s point and would wait for him to clarify.

I believe the text in draft-ietf-spring-srv6-network-programming clears says what locator block and locator node are. What more details do you think are required? [Bruno] Speaking as an individual, the draft could possibly clarify the usage of these information/fields by the receiver. Possibly using the same name/term (e.g. SRv6 SID Locator Block length) to ease the references between both drafts.
