Les, As an individual contributor, I have a clarification question regarding Segment Identifier Conflicts https://tools.ietf.org/html/draft-ginsberg-spring-conflict-resolution-00#section-3 In the IGP, (Prefix, SID) mapping may be advertised via either Prefix-SID (sub-TLV attached to an IP Prefix) or Mapping Server (Mapping Server Prefix-SID in the Binding TLV). The draft generalizes both by defining and using a generalized mapping entry. Hence the draft seems to make no distinction between Prefix-SID and Remote-Binding SID advertised by the Mapping Server. Is this a correct understanding?
OTOH, the "IS-IS Extensions for Segment Routing" IS-IS WG draft, specify that a distinction must be made: " For a given prefix, if both a MS entry with its Prefix-SID Sub-TLV and a Prefix TLV (e.g.: TLV135) with its Prefix-SID are received, the Prefix-SID advertised within the Prefix TLV MUST be preferred while the MS entry MUST be ignored." https://tools.ietf.org/html/draft-ietf-spring-segment-routing-06#section-3.6.1 So is your intention to: - change the IS-IS specification to remove this rule (preference for Prefix-SID Sub-TLV)? - or adapt your draft to accommodate for this rule?
