Summary: this document introduces a new link attribute advertisement in OSPFv2 and OSPFv3 to address general link properties needed for new applications, such as Segment Routing.
The document has good description on the TLV structure of the Application specific Advertisements, but fails to describe what are the NEW Link attributes needed by Segment Routing.
Page 7 (section 5) has a really good description on all the link properties added to OSFP (RFC4203, RFC 7308, RFC7471, RFC3630) to achieve TE.
I can see Segment Routing would need each node to advertise its own SID and the SIDs of adjacent nodes. Can't they be encoded (or extended) in OSPF's NODE ID?
