Ting,
there is a concept of SR Mapping Server, which can be used to advertise
SIDs for prefixes from the central place.
draft-ietf-ospf-segment-routing-extensions defines the OSPF Extended
Prefix Range TLV in section 4 which is used to advertise the SID
mappings by SRMS. Similarly ISIS SR drafts defines a similar mechanism
in ISIS. There are already implementations that support SRMS.
What you defined in your draft looks very similar to SRMS and we
definitely do not need two different ways to achieve the same goal.
regards,
Peter
