Hi authors,

Please find below two comments:

1) Following the work done in draft-ginsberg-spring-conflict-resolution, would you consider adding a notification to report SRGB block inconsistency?
I think that there is consensus that the network operator need to be warned about this issue.

2) Regarding "notification segment-routing-global-sid-collision", what about adding the "identity" of both SR nodes (the one advertising the "received-target" and the one advertising the "original-target")? This looks useful as the network operator will likely need to look at the configuration of both of these nodes, and possibly fixe one.

As a side note, "leaf routing-protocol" seems to assume that the check is not done across routing-instances, while I think there is the option that the SRGB be common for all routing protocols hence a use case to detect sid-collision across routing protocol/instances.

Many thanks,
Regards,
Bruno
