Hi Les, When talking about SID conflicts I think the document should spell out what it means by SID.
Indeed, the architecture document defines SID as: "SID: a Segment Identifier. Examples of SIDs are: a MPLS label, an index value in a MPLS label space, an IPv6 address. Other types of SIDs can be defined in the future." https://tools.ietf.org/html/draft-ietf-spring-segment-routing-08#section-2 Indeed, when talking about SID conflicts - it matters that we do not compare apple and orange i.e. MPLS labels and index in SRGB. - we can't compare index from different protocols (e.g. OSPF & IS-IS) unless they advertise the same SRGB (which is only a specific case). So either the document considers that a SID is an "index" and in this case, we just can't compare them across protocols. Or it consider that a SID is a "MPLS labels" and in this case, as the IGP advertisement typically advertise index for global SIDs, there is a need to maps the received SID advertisement into the SRGB of the local node. This needs to be crystal clear.
