The IESG has approved the following document:
- 'IS-IS Flood Reflection'

This document is the product of the Link State Routing Working Group.

The IESG contact persons are Alvaro Retana, Andrew Alston and John Scudder.

Technical Summary:

This document provides extensions to IS-IS to support flooding reflection of
IS-IS updates in a level-1 area used for level-2 transit. This reduces the
requirement for a full mesh of adjacencies between Area Border Routers (ABRs)
and allows the flooding reflection to be done by the server which doesn't
necessarily participate in the data plane. The document also describes bbut
tunneled and non-tunneled transit in the level-1 area.

Working Group Summary:

There is stong support among those reviewing the document. However, there was
at least one WG participant who thought the WG would select one of the
alternatives among those proposed rather than advancing experimental solutions
with sufficent momentum.

Document Quality:

The document is of high quality although at least WG member believed the
solution was too complex.

Personnel:

 Document Shepherd: Acee Lindem
 Responsible AD: John Scudder
