Technical Summary
Each OSPF prefix can be advertised with an 8-bit field to indicate
specific properties of that prefix. However, all the OSPFv3 Prefix
Options bits have already been assigned and only a few bits remain
unassigned in the flags field of the OSPFv2 Extended Prefix TLV.
This document solves the problem of insufficient prefix options bits
by defining variable-length Prefix Attribute Flags Sub-TLV for OSPF.
Working Group Summary
Was there anything in the WG process that is worth noting?
For example, was there controversy about particular points
or were there decisions where the consensus was
particularly rough?
This is a simple OSPF maintenance document that adds TLVs for OSPF prefixes.
Document Quality
Are there existing implementations of the protocol? Have a
significant number of vendors indicated their plan to
implement the specification? Are there any reviewers that
merit special mention as having done a thorough review,
e.g., one that resulted in important changes or a
conclusion that the document had no substantive issues? If
there was a MIB Doctor, Media Type, or other Expert Review,
what was its course (briefly)? In the case of a Media Type
Review, on what date was the request posted?
No implementations yet, however new WG documents (draft-ietf-lsr-anycast-flag) requires this technology
