Chris – One of the early mistakes that was made when defining SR-MPLS was defining the N-flag (and R-flag) in the Prefix-SID sub-TLV. We quickly realized that these flags had meaning and use cases for the prefix – not simply for the SID. RFC 7794 was then written and these flags were

Dear Acee, Chris and LSR WG, In the Post Multi-Chassis era, it is more and more common to consider CLOS design for core router (aka De-segregated router). Unlike data center, it requires to run LSR in the “fabric” and dramatically increase the numbers of LSR speakers in the core network. So,

Hi Acee, We'll update the text as follows in sec 8 to clarify this. Please let know if this works. All End.X SIDs MUST be subsumed by the subnet of a Locator with the matching algorithm which is advertised by the same node in an SRv6 Locator TLV. End.X SIDs which do not meet this
