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.

Major issues:
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

Minor issues:

Nits/editorial comments:
