Technical Summary
It is useful for routers in OSPFv2 and OSPFv3 routing domains to be
able to associate tags with prefixes. Previously, OSPFv2 and OSPFv3
were relegated to a single tag and only for AS External and Not-So-
Stubby-Area (NSSA) prefixes. With the flexible encodings provided by
OSPFv2 Prefix/Link Attribute Advertisement and OSPFv3 Extended LSAs,
multiple administrative tags may be advertised for all types of
prefixes. These administrative tags can be used for many
applications including route redistribution policy, selective prefix
prioritization, selective IP Fast-ReRoute (IPFRR) prefix protection,
and many others.
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?
There has been no controversy and a strong and broad consensus for publishing this document.
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 known implementations exist however, there are a couple existing drafts that need to use the
feature (draft-cheng-lsr-igp-shortcut-enhancement, draft-li-lsr-igp-based-intra-domain-savnet).
Personnel
The Document Shepherd for this document is Christian Hopps. The
