Hi Bruno, thanks for the comment. I’d propose following text: The Originator SRGB TLV contains the SRGB of the node originating the prefix to which the BGP Prefix-SID is attached. The Originator SRGB TLV MUST NOT be changed during the propagation of the BGP update. Let me know if address your concern.
